Product details
Overview
74ALVC164245DGG,11 from Nexperia is a 16-bit dual-supply translating transceiver in TSSOP48 package, designed for bidirectional level translation between 3 V and 5 V buses. It features two independent 8-bit channels (1A/1B and 2A/2B), non-inverting 3-state outputs, separate direction (1DIR/2DIR) and output enable (1OE/2OE) controls per channel, and operates across -40 °C to +125 °C. It enables interoperability in mixed-voltage embedded systems such as industrial PLC I/O modules.
For engineers reviewing the 74ALVC164245DGG,11 datasheet, 74ALVC164245DGG,11 pinout, 74ALVC164245DGG,11 application, or 74ALVC164245DGG,11 equivalent, this page delivers verified electrical parameters, validated dual-rail voltage operation (VCC(A): 1.5–3.6 V; VCC(B): 1.5–5.5 V), real-world timing data (tpd down to 1.0 ns), thermal derating guidance, and confirmed pin mapping for SOT362-1.
Technical Context
This device implements dual-rail CMOS logic with independent A-side (3 V domain) and B-side (5 V domain) supply references: VCC(A) powers pins 1A0–1A7, 2A0–2A7, 1DIR, 2DIR, 1OE, 2OE, and VCC(A); VCC(B) powers 1B0–1B7, 2B0–2B7 and VCC(B). Direction control is active-HIGH on nDIR: HIGH enables A→B flow; LOW enables B→A flow.
IOFF circuitry ensures no current flows from powered to unpowered rail during suspend mode (e.g., VCC(A) = 0 V), provided nAn outputs are held in 3-state and A-bus voltage stays below 0.7 V. Output enable inputs (1OE/2OE) are active-LOW and referenced to VCC(A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.5 V to 3.6 V - supports 1.8 V, 2.5 V, and 3.3 V logic domains on A-side |
| VCC(B) Range | 1.5 V to 5.5 V - compatible with 3.3 V and 5 V TTL/CMOS buses on B-side |
| Propagation Delay (tpd) | 1.0 ns (min) to 7.5 ns (max) - measured A↔B under VCC(A)=3.0–3.6 V / VCC(B)=4.5–5.5 V, CL=50 pF |
| Enable/Disable Time (ten/tdis) | 1.0–12.0 ns - defines minimum bus turnaround latency when toggling OE signals |
| IOFF Current | < ±0.1 μA - prevents back-powering and leakage when one supply is off |
| ESD Rating | HBM > 2000 V, CDM > 1000 V - meets JEDEC JS-001/JS-002 for robust board handling |
| Operating Temperature | -40 °C to +125 °C - qualified for extended industrial and automotive-adjacent environments |
Pinout & Package
TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR (Pins 1, 24) | Direction control input | Active-HIGH: enables A→B data flow; active-LOW enables B→A; referenced to VCC(A) |
| 1OE, 2OE (Pins 48, 25) | Output enable input | Active-LOW: disables both A and B ports into high-impedance state; referenced to VCC(A) |
| 1A0–1A7, 2A0–2A7 (Pins 37–47, 26–36) | A-side data I/O | Bi-directional bus interface pins referenced to VCC(A); tolerate up to 5.5 V input |
| 1B0–1B7, 2B0–2B7 (Pins 2–12, 13–23) | B-side data I/O | Bi-directional bus interface pins referenced to VCC(B); overvoltage tolerant to 5.5 V |
| VCC(A) (Pins 31, 42) | A-side supply | Power rail for A-port logic and control inputs (nDIR, nOE); must be ≤ VCC(B) except in suspend mode |
| VCC(B) (Pins 7, 18) | B-side supply | Power rail for B-port logic; supports full 5 V TTL compatibility and higher drive strength |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight dedicated ground connections minimize noise coupling and improve signal integrity |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail voltage translation | Simultaneous 1.5–3.6 V (A) ↔ 1.5–5.5 V (B) operation without external components |
| IOFF partial power-down | Blocks current flow between rails when either VCC(A) or VCC(B) = 0 V, enabling safe hot-swap |
| Overvoltage-tolerant inputs | All A- and B-side inputs withstand up to 5.5 V regardless of supply voltage, simplifying mixed-voltage design |
| High-speed bus turnaround | Enable/disable times as low as 1.0 ns reduce dead time between read/write cycles on shared buses |
| Industrial temperature range | Full functionality guaranteed from -40 °C to +125 °C, supporting harsh-environment control applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply translating transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC16T245DGGR | TI part with identical 16-bit dual-rail architecture but wider VCC(A) range (1.2–3.6 V) and lower typical tpd (0.9 ns at 3.3 V/5 V) | Supports 1.2 V I/O domains; lacks IOFF in suspend mode - requires external isolation for zero-VCC safety | Select when interfacing with ultra-low-voltage FPGAs and external power sequencing is controlled. |
| 74LVC16T245PWJ | Nexperia LVC variant with same pinout but narrower VCC(B) range (1.65–3.6 V); no 5 V tolerance on B-side | Only suitable for 3.3 V ↔ 3.3 V or 1.8 V ↔ 3.3 V translation; cannot replace 5 V bus interfaces | Choose only for cost-sensitive 3 V-only systems where 5 V compatibility is unnecessary. |

FAQ
Can 74ALVC164245DGG,11 operate with VCC(A) = 2.5 V and VCC(B) = 5.0 V?
Yes. The device is fully specified for VCC(A) from 1.5 V to 3.6 V and VCC(B) from 1.5 V to 5.5 V, including the 2.5 V/5.0 V combination. Static and dynamic parameters - including VIH/VIL thresholds, VOH/VOL levels, and tpd - are characterized across this range per Tables 5–7 of the datasheet Rev. 13.
What happens if VCC(A) = 0 V while VCC(B) = 5 V?
In suspend mode, the IOFF circuitry disables conduction between rails. As long as 1A/2A outputs are held in 3-state (via 1OE/2OE HIGH) and A-bus voltage remains below 0.7 V, leakage current is limited to ±0.1 μA. This prevents back-powering and satisfies JESD78 Class II latch-up immunity.
Is the 74ALVC164245DGG,11 pin-compatible with older 74LVC164245 variants?
No. While functionally similar, the 74ALVC164245 uses a different pinout than legacy 74LVC164245 packages (e.g., SSOP48). Pin numbering and terminal assignments - especially GND, VCC(A), and VCC(B) locations - differ between SOT362-1 (TSSOP48) and SOT370-1 (SSOP48). Layout redesign is required for replacement.
Does this device support hot-plug insertion into a live 5 V bus?
Yes, when used per datasheet guidelines: ensure 1OE/2OE are HIGH (3-state) before applying VCC(A), limit A-bus voltage to < 0.7 V during power-up, and rely on IOFF to block current. The device's overvoltage-tolerant inputs (to 5.5 V) and HBM > 2000 V rating further support controlled hot-swap deployment in field-replaceable modules.
