Product details
Overview
ADG3301BKSZ-REEL from Analog Devices is a single-channel, bidirectional logic level translator supporting 1.15 V to 5.5 V operation across dual supplies (VCCA ≤ VCCY), delivering up to 60 Mbps data rate in A→Y direction at 2.5 V/3.3 V, with <5 µA quiescent current and no direction pin. It enables voltage translation between low-voltage microcontrollers (e.g., 1.2 V/1.8 V) and higher-voltage peripherals (e.g., 3.3 V/5 V) in compact portable systems.
For engineers reviewing the ADG3301BKSZ-REEL datasheet, ADG3301BKSZ-REEL pinout, ADG3301BKSZ-REEL application, or ADG3301BKSZ-REEL equivalent, key selection criteria include guaranteed bidirectional operation without direction control, enable-driven three-state capability, supply voltage compatibility constraints (VCCA must be ≤ VCCY), and performance trade-offs across VCCA/VCCY combinations and load capacitance.
Technical Context
The ADG3301BKSZ-REEL implements a one-shot accelerator architecture with PMOS/NMOS transistor pairs (T1–T4) triggered by edge detection to achieve fast rise/fall times. Translation occurs natively in both A→Y and Y→A directions without external direction signals, using separate supply references: VCCA sets logic thresholds on the A side, VCCY on the Y side.
Enable (EN) is referenced to VCCA and controls high-impedance states on both A and Y pins simultaneously. The device requires strict power-up sequencing (VCCY before VCCA) to prevent VCCA > VCCY violations, and supports CMOS-compatible loads with input driving requirements ≤150 Ω output impedance and ≥36 mA peak drive capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Range | VCCA: 1.15 V to 5.5 V; VCCY: 1.65 V to 5.5 V; VCCA must be ≤ VCCY for safe operation |
| Max Data Rate | 60 Mbps (A→Y, VCCA = 2.5 V, VCCY = 3.3 V, CL = 50 pF); 25 Mbps (A→Y, VCCA = 1.2 V, VCCY = 1.8 V) |
| Propagation Delay | 4–12 ns (Y→A), 6–25 ns (A→Y), depending on VCCA/VCCY and load |
| Quiescent Current | <5 µA total (ICCA + ICCY), enabling battery-sensitive designs |
| Enable Function | Active-high EN referenced to VCCA; places both A and Y pins in high-Z state when low |

Pinout & Package
The ADG3301BKSZ-REEL is housed in a JEDEC-compliant 6-lead SC70 (KS-6) package, measuring 2.00 mm × 1.25 mm × 0.90 mm, optimized for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCCA | Power supply input for A-side I/O | Sets logic thresholds (VIHA/VILA) on A pin; must be ≤ VCCY |
| 2 - A | Bidirectional I/O referenced to VCCA | Accepts/transmits VCCA-compatible logic; translates to/from Y side automatically |
| 3 - GND | Analog/digital ground reference | Common return path for both supplies; requires low-inductance layout |
| 4 - EN | Active-high enable control | Referenced to VCCA; drives A/Y into high-Z when low; supports VCCA- or VCCY-level logic |
| 5 - Y | Bidirectional I/O referenced to VCCY | Accepts/transmits VCCY-compatible logic; bidirectionally coupled to A pin |
| 6 - VCCY | Power supply input for Y-side I/O | Sets logic thresholds (VIHY/VILY) on Y pin; powers Y-side output stage |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional translation without direction pin | Eliminates timing-critical direction control signals and reduces GPIO count in MCU interfaces |
| One-shot accelerator architecture | Enables sub-10 ns propagation delays and <5 ns rise/fall times via edge-triggered PMOS/NMOS switching |
| VCCA-referenced enable input | Allows direct control from low-voltage host (e.g., 1.2 V ASIC) without level-shifting EN |
| Low leakage in three-state mode | ±1 µA max leakage per I/O pin (A/Y) when EN = 0, preserving signal integrity on shared buses |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0101DCKR | Single-channel, 1.65–5.5 V operation; auto-direction sensing; 60 Mbps max; SC70-6 package | No VCCA/VCCY separation-uses single supply with internal regulators; less flexible for asymmetric voltage pairs (e.g., 1.2 V ↔ 3.3 V) | Prefer TXS0101DCKR when system uses only one supply rail and requires simpler biasing; ADG3301BKSZ-REEL better for precise dual-rail control. |
| SN74AVC1T45DBVR | Single-channel, 1.2–3.6 V operation; direction pin required; 500 Mbps max; SOT-23-6 package | Requires external direction control signal; wider voltage range on Y side but narrower overall (no 5 V support); higher speed but higher quiescent current (~10 µA) | Choose SN74AVC1T45DBVR for high-speed, direction-controlled links where PCB layout allows dedicated DIR trace; ADG3301BKSZ-REEL preferred for directionless, ultra-low-power use cases. |
Compared with TXS0101DCKR and SN74AVC1T45DBVR, the ADG3301BKSZ-REEL uniquely supports independent VCCA/VCCY rails down to 1.15 V, delivers sub-5 µA quiescent current, and eliminates direction-pin timing constraints-making it optimal for asymmetric, battery-powered multivoltage systems where supply flexibility and power efficiency are critical.

FAQ
What is the maximum allowable voltage difference between VCCA and VCCY for reliable operation of the ADG3301BKSZ-REEL?
The ADG3301BKSZ-REEL requires VCCA ≤ VCCY at all times, with absolute maximum ratings specifying VCCA to GND ≤ +7 V and VCCY to GND ≤ VCCA + 7 V. For guaranteed specification compliance, VCCA must remain within 1.15 V to VCCY, and VCCY must be 1.65 V to 5.5 V. Exceeding VCCA > VCCY-even momentarily during power-up-may cause latch-up or permanent damage.
Does the ADG3301BKSZ-REEL support level translation from 5 V down to 1.2 V?
No, the ADG3301BKSZ-REEL does not support 5 V → 1.2 V translation. Its architecture mandates VCCA ≤ VCCY, so the lower-voltage domain must be connected to the A pin (VCCA) and the higher-voltage domain to the Y pin (VCCY). Thus, 1.2 V → 5 V is supported, but reverse translation requires a different topology or part.
How does the enable (EN) pin function in the ADG3301BKSZ-REEL, and what logic levels can drive it?
The EN pin is active-high and referenced to VCCA. It places both A and Y pins in high-impedance state when low. It accepts VCCA-compatible logic (VIHEN = 0.65 × VCCA min) and is also compatible with VCCY-level signals due to internal design-enabling direct drive from either supply domain without external level shifting.
What is the guaranteed data rate for ADG3301BKSZ-REEL when translating between 1.8 V and 3.3 V supplies?
At VCCA = 1.8 V and VCCY = 3.3 V, the ADG3301BKSZ-REEL guarantees 50 Mbps in both A→Y and Y→A directions under specified test conditions (CL = 50 pF for A→Y, CL = 15 pF for Y→A). Performance degrades at lower VCCA (e.g., 1.2 V→1.8 V yields 25 Mbps) due to reduced drive strength.
Can the ADG3301BKSZ-REEL be used in I²C bus applications?
Yes, the ADG3301BKSZ-REEL supports I²C level translation in standard-mode (100 kHz) and fast-mode (400 kHz) configurations. Its bidirectional operation, low capacitance (CA = 9 pF, CY = 6 pF), and ability to handle open-drain pull-ups make it suitable for bridging 1.8 V/3.3 V I²C segments-though external pull-up resistors must be placed on each side per I²C specification.
