Product details
Overview
74LVC8T245PW-Q100 from Nexperia is an automotive-qualified 8-bit dual-supply translating transceiver with 3-state outputs, enabling bidirectional level translation between 1.2 V and 5.5 V domains. It features independent VCC(A) and VCC(B) supplies, DIR-controlled data direction, OE-gated 3-state output control, and IOFF circuitry for partial power-down isolation. Used in automotive infotainment backplanes to interface 1.8 V microcontrollers with 3.3 V display drivers.
For engineers reviewing the 74LVC8T245PW-Q100 datasheet, 74LVC8T245PW-Q100 pinout, 74LVC8T245PW-Q100 application, or 74LVC8T245PW-Q100 equivalent, key selection criteria include dual-rail voltage flexibility (1.2–5.5 V per rail), AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), 420 Mbps max data rate (3.3 V → 5.0 V), IOFF-enabled suspend mode, and TSSOP24 package with side-wettable flanks for AOI.
Technical Context
This device implements a dual-voltage bidirectional bus transceiver architecture with separate input-reference domains: An, DIR, and OE pins are referenced to VCC(A); Bn pins are referenced to VCC(B). Direction control is synchronous and edge-independent - DIR HIGH enables A→B transmission, DIR LOW enables B→A transmission.
The IOFF circuit ensures leakage current remains ≤±2 μA when either VCC rail is at GND, placing both ports in high-impedance OFF-state during suspend mode. Active bus hold (in 74LVCH8T245 variant) is not present in this 74LVC8T245PW-Q100 version, confirmed by static characteristics tables showing no IBHL/IBHH values under "74LVC8T245-Q100" column headers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A): 1.2 V to 5.5 V; VCC(B): 1.2 V to 5.5 V - supports translation across all common low-voltage nodes (1.2/1.5/1.8/2.5/3.3/5.0 V). |
| Max Data Rate | 420 Mbps (3.3 V → 5.0 V) - enables high-speed inter-domain communication in ADAS sensor hubs and domain controllers. |
| Propagation Delay | 5.4 ns (An→Bn, VCC(A)=3.3 V, VCC(B)=5.0 V) - ensures timing-critical signal integrity in real-time automotive control loops. |
| IOFF Leakage | ≤±2 μA at −40 °C to +125 °C - guarantees safe hot-insertion and rail sequencing in multi-supply automotive ECUs. |
| ESD Rating | HBM: >4000 V; CDM: >1000 V - meets stringent automotive board-level ESD immunity requirements per ISO 10605. |
| Operating Temp | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cockpit applications. |
| Output Drive | ±24 mA at VCC = 3.0 V - drives 50 Ω transmission lines or multiple CMOS inputs without external buffers. |
Pinout & Package
TSSOP24 package (SOT355-1), 4.4 mm body width, 0.65 mm pitch, side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 23, 24 | VCC(B) | Supply reference for B-port I/Os; supports independent voltage domain from A-side. |
| 2 | DIR | Direction control input (VCC(A)-referenced); HIGH = A→B, LOW = B→A. |
| 3–10 | A1–A8 | Bi-directional data port A (VCC(A)-referenced); connects to low-voltage MCU or ASIC. |
| 11–13 | GND | Common ground return; all three pins must be connected to 0 V for stable operation. |
| 14–21 | B1–B8 | Bi-directional data port B (VCC(B)-referenced); interfaces higher-voltage peripherals (e.g., displays, sensors). |
| 22 | OE | Active-LOW output enable (VCC(A)-referenced); disables both ports into high-Z state for bus isolation. |
| 1 | VCC(A) | Supply reference for A-port I/Os, DIR, and OE; decoupling required near pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply translation | Independent 1.2–5.5 V rails on A and B sides eliminate need for external level shifters in mixed-voltage systems. |
| IOFF partial power-down | Prevents damaging backflow current when one supply is off - critical for modular ECU power gating. |
| AEC-Q100 Grade 1 | Qualified for automotive use from −40 °C to +125 °C ambient, including extended temperature stress testing. |
| 3-state bus isolation | OE-controlled high-impedance outputs allow shared bus arbitration in multi-master vehicle networks. |
| High noise immunity | Guaranteed VIH/VIL margins across all voltage combinations reduce susceptibility to coupled transients in noisy harness environments. |

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 |
|---|---|---|---|
| 74LVCH8T245PW-Q100 | Includes active bus hold circuitry on all I/Os; otherwise identical pinout, voltage range, and timing. | Preferred where floating inputs may occur (e.g., unpopulated test points or hot-swap connectors) to prevent undefined logic states. | Select when deterministic input biasing is required without external pull resistors. |
| SN74AVC8T245RHLR | Texas Instruments part; same 8-bit dual-supply function but rated only to +85 °C (non-automotive), different IOFF behavior, and no AEC-Q100 qualification. | Suitable for industrial or consumer applications with less stringent temperature and reliability requirements. | Use only in non-automotive designs where AEC-Q100 compliance is not mandated. |
Compared with 74LVCH8T245PW-Q100, this 74LVC8T245PW-Q100 omits bus hold for lower static current (30 μA vs. ~50 μA) and reduced input capacitance - advantageous in high-density, low-power automotive modules. Versus SN74AVC8T245RHLR, it delivers guaranteed +125 °C operation and automotive-grade ESD/IOFF robustness essential for ECU deployment.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
No maximum differential is specified - both supplies operate independently within 1.2 V to 5.5 V. The device functions correctly with VCC(A) = 1.2 V and VCC(B) = 5.0 V simultaneously, enabling direct 1.2 V ↔ 5.0 V translation without intermediate rails or regulators.
Does 74LVC8T245PW-Q100 support hot insertion?
Yes - its IOFF circuitry ensures ≤±2 μA leakage when either VCC rail is at 0 V, preventing backdrive current into powered domains. This allows safe live insertion into partially powered systems, such as adding a new sensor module to an active ADAS domain controller backplane.
Can OE and DIR be tied together for unidirectional operation?
No - OE and DIR serve distinct functions: DIR controls data direction (A↔B), while OE enables/disables outputs (HIGH = disabled). Tying them risks incorrect bus states. For unidirectional use, fix DIR to constant HIGH or LOW and control data flow via OE and upstream logic.
Is external termination required for 420 Mbps operation?
Yes - at 420 Mbps (3.3 V → 5.0 V), signal integrity requires controlled-impedance PCB routing (e.g., 50 Ω microstrip) and point-to-point topology. External series termination (22–33 Ω) at the driver end is recommended to suppress reflections, especially over >5 cm traces.
