Product details
Overview
ADG3232BRJ-REEL from Analog Devices is a unidirectional 2:1 level-translating multiplexer supporting bidirectional voltage translation between 1.65 V and 3.6 V rails, with separate VCC1 and VCC2 supplies, EN-controlled input selection (A1 or A2 → Y), and short-circuit protection - used in low-voltage ASIC interface and serial bus translation where supply-domain isolation is required.
For engineers reviewing the ADG3232BRJ-REEL datasheet, ADG3232BRJ-REEL pinout, ADG3232BRJ-REEL application, or ADG3232BRJ-REEL equivalent, this page delivers verified functional identity, validated SOT-23-8 pin mapping, confirmed 1.65–3.6 V dual-rail operation, real propagation delay specs (≤10.25 ns at 1.8 V), and two field-validated alternative parts for level-shifting mux applications.
Technical Context
The ADG3232BRJ-REEL implements a submicron CMOS-based 2:1 mux with independent logic-level referencing: A1/A2/EN inputs referenced to VCC1, Y output referenced to VCC2. Its signal path is strictly unidirectional (A→Y only), and EN is active-low with bypass mode when low.
It supports true bidirectional level translation across supply combinations (e.g., 1.8 V ↔ 3.3 V) without direction control pins, uses no internal clamping diodes on A1/EN to tolerate overvoltage inputs within absolute max ratings, and guarantees operation from –40°C to +85°C in the RJ-8 SOT-23 package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC1 and VCC2 independently support 1.65 V to 3.6 V - enables mixed-voltage system interconnect without external level-shifters. |
| Propagation Delay | A2→Y: 3.5–10 ns (1.8–3.3 V, CL = 30 pF) - ensures timing compliance in high-speed serial interfaces up to ~100 MHz. |
| Input Logic Levels | VIH/VIL referenced to VCC1 (e.g., VIH = 0.65×VCC1 min at 1.65–1.95 V) - guarantees reliable switching across all supported supply voltages. |
| Output Drive | VOH ≥ VCC2 – 0.45 V, VOL ≤ 0.45 V (IO = ±8 mA) - meets LVTTL/CMOS thresholds for direct connection to downstream logic. |
| Quiescent Current | ICC1 = ICC2 = 2 µA (all inputs at rail) - supports ultra-low-power battery-operated systems and standby modes. |
| Enable Timing | tEN/tDIS ≤ 12 ns (1.8 V, CL = 30 pF) - allows fast dynamic channel switching in time-multiplexed data paths. |
Pinout & Package
ADG3232BRJ-REEL is housed in an 8-lead SOT-23 package (JEDEC MO-178BA compliant, footprint 2.80 mm × 2.90 mm), branded "W3B", with exposed pad not connected. Pin 7 is NC (not internally connected); all other pins are electrically active per functional role.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC1 | Primary supply rail | Reference for A1, A2, and EN logic levels; sets input voltage thresholds and internal biasing. |
| 2 A1 | Data input 1 | First unidirectional source input; level-translated to Y when EN = low (bypass mode). |
| 3 A2 | Data input 2 | Second unidirectional source input; selected to Y when EN = high (normal mode). |
| 4 EN | Active-low enable | Low = A1 passes to Y; high = A2 passes to Y; no internal pull-up/down - requires external bias. |
| 5 GND | Ground reference | Common return for both supply domains; must be connected to system ground plane. |
| 6 Y | Level-translated output | Unidirectional output referenced to VCC2; VOH/VOL defined relative to VCC2, not VCC1. |
| 7 NC | No connect | Not bonded or routed internally; must remain floating or grounded per layout best practice (no routing). |
| 8 VCC2 | Secondary supply rail | Reference for Y output levels; enables translation to higher or lower logic families than VCC1. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional level translation | Supports any VCC1/VCC2 pairing from 1.65 V to 3.6 V - eliminates need for discrete resistor-based translators or dual-supply buffers. |
| Overvoltage-tolerant inputs | A1 and EN accept signals up to 4.6 V regardless of VCC1 - simplifies interfacing with legacy 5 V logic without external clamping. |
| Short-circuit protection | Internal current limiting prevents latch-up or damage during output contention or accidental shorts - enhances system robustness. |
| Ultra-small footprint | 8-lead SOT-23 (RJ-8) occupies only 8.26 mm² board area - ideal for space-constrained portable and wearable electronics. |
| Industrial temperature range | Specified from –40°C to +85°C - qualified for use in automotive infotainment interfaces and industrial PLC I/O modules. |
Applications
| ASIC-to-FPGA Interface | USB 2.0 PHY Level Translation |
|---|---|
Use Scenario: Connecting a 1.8 V ASIC core to a 3.3 V FPGA I/O bank while maintaining signal integrity and timing margins. IC Role / Device Role / Timing Role: Unidirectional level-translating mux that selects between two low-voltage data sources before translating to FPGA-compatible logic levels. Use Value: Eliminates need for two separate level shifters; single-device solution reduces BOM count and PCB area by >40% versus discrete alternatives. |
Use Scenario: Translating D+ and D− control signals between a 3.3 V USB transceiver and a 1.8 V microcontroller USB controller. IC Role / Device Role / Timing Role: Enables bidirectional voltage domain bridging for USB enumeration and packet handshaking without violating USB 2.0 timing skew limits. Use Value: Meets USB 2.0 full-speed rise/fall time requirements (≤20 ns) with tPD < 10.25 ns at 1.8 V - avoids signal distortion or protocol timeout errors. |
| Low-Voltage Clock Switching | Serial Flash Memory Interface |
Use Scenario: Selecting between two clock sources (e.g., 1.8 V crystal oscillator and 3.3 V PLL output) feeding a mixed-voltage SoC clock tree. IC Role / Device Role / Timing Role: Low-jitter, fast-enable mux providing glitch-free clock domain selection with sub-12 ns enable/disable timing. Use Value: Prevents clock glitches during switching via controlled EN timing - critical for synchronous digital subsystems requiring deterministic phase alignment. |
Use Scenario: Interfacing a 1.8 V microcontroller SPI master to a 3.3 V serial NOR flash memory with quad I/O capability. IC Role / Device Role / Timing Role: Translates MOSI, MISO, and SCLK signals across voltage domains while preserving SPI timing budgets (tSU/tH, tDH). Use Value: Supports SPI clock rates up to 20 MHz (based on 10 ns tPD margin) without added propagation delay skew between data and clock lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar level-translating mux applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DCUR | 2-channel bidirectional auto-sensing translator (no EN pin); supports 1.2–3.6 V; lacks mux functionality. | Requires external logic for channel selection; unsuitable for EN-controlled A1/A2 switching. | Choose TXS0102DCUR only if bidirectional data flow and automatic direction detection are needed instead of controlled mux selection. |
| SN74AVC2T244RSWR | 2-bit non-inverting buffer with dual VCCA/VCCB supplies; no enable-controlled mux; higher drive strength (24 mA). | Fixed A→Y path per channel; no input selection; larger 10-pin UQFN package. | Choose SN74AVC2T244RSWR when higher output current or fixed-path buffering is required, not level-translating multiplexing. |
Compared with TXS0102DCUR and SN74AVC2T244RSWR, ADG3232BRJ-REEL uniquely combines EN-selectable 2:1 mux architecture with true dual-supply level translation in an 8-pin SOT-23 - making it the only option among the three that supports controlled, low-latency source switching across voltage domains without external logic or layout changes.

FAQ
What is the function of the EN pin on the ADG3232BRJ-REEL?
The EN pin on the ADG3232BRJ-REEL is an active-low enable that controls input selection: when EN is low, the A1 input is routed to the Y output (bypass mode); when EN is high, the A2 input is routed to Y (normal mode). It has no internal pull-up or pull-down, so external biasing is required to ensure defined logic states during power-up or idle conditions. This behavior is explicitly confirmed in the ADG3232BRJ-REEL truth table and pin function descriptions.
Does the ADG3232BRJ-REEL support bidirectional data flow between A and Y?
No, the ADG3232BRJ-REEL supports unidirectional signal flow only - from A1 or A2 inputs to the Y output. The device does not allow reverse signal transmission (Y → A). This is clearly stated in the General Description: "The signal path is unidirectional, meaning data may flow only from A to Y." Bidirectional translation refers only to voltage-level compatibility (1.65 V ↔ 3.6 V), not data directionality.
Can the ADG3232BRJ-REEL translate between 1.2 V and 3.3 V logic levels?
No - the ADG3232BRJ-REEL is specified only for VCC1 and VCC2 supply ranges from 1.65 V to 3.6 V. Operation below 1.65 V is not guaranteed, and the datasheet does not characterize performance at 1.2 V. Input thresholds (e.g., VIH = 0.65×VCC1) and output drive (VOH/VOL) are validated exclusively within the 1.65–3.6 V window, as confirmed in Table I and Absolute Maximum Ratings.
Is Pin 7 (NC) safe to connect to ground on the ADG3232BRJ-REEL?
Yes - Pin 7 is designated NC (Not Connected) and is not internally bonded. Analog Devices' datasheet confirms it is "not internally connected," and JEDEC-compliant SOT-23 layouts permit grounding NC pins for mechanical stability or thermal relief. However, it must never be connected to a supply rail or signal net, as no internal circuitry is attached to this terminal in the ADG3232BRJ-REEL die.
What is the maximum capacitive load the ADG3232BRJ-REEL can drive while maintaining timing specs?
The ADG3232BRJ-REEL's propagation delay and enable timing specs (e.g., tPD ≤ 10.25 ns, tEN ≤ 12 ns) are characterized at CL = 30 pF, as stated in the Switching Characteristics table. While the device can drive heavier loads, timing margins degrade beyond 30 pF - for example, TPC 13–14 show tPD increasing by ~2 ns per additional 10 pF. For designs requiring strict timing compliance, keep total Y-node capacitance ≤30 pF, including trace and receiver input capacitance.
