Product details
Overview
74LVC245APW-Q100 from Nexperia is an automotive-qualified octal bus transceiver with 3-state outputs, direction control (DIR), and active-low output enable (OE). It operates from 1.2 V to 3.6 V supply, tolerates 5.5 V inputs, and supports bidirectional data translation between 3.3 V and 5 V logic domains in automotive body control modules. Schmitt-trigger inputs ensure robustness against slow signal edges.
For engineers reviewing the 74LVC245APW-Q100 datasheet, 74LVC245APW-Q100 pinout, 74LVC245APW-Q100 application, or 74LVC245APW-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), IOFF partial power-down protection, 5 V-tolerant I/O, TSSOP20 package with side-wettable flanks, and bus hold functionality (in LVCH variant).
Technical Context
This device implements a dual-bus, bidirectional 8-bit data path controlled by DIR and OE signals. When OE is LOW, outputs drive A↔B data in the direction set by DIR; when OE is HIGH, all outputs enter high-impedance state. The IOFF circuit actively disables outputs during power-down to prevent backflow current.
Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), enabling reliable operation with slow-rising signals common in automotive wiring harnesses. Bus hold (on 74LVCH245A-Q100 variant) maintains last valid logic state on un-driven data inputs without external pull resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.2 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains |
| Input voltage tolerance | Up to 5.5 V - allows safe connection to legacy 5 V microcontrollers or sensors without level-shifting |
| Propagation delay | 1.5 ns to 8.0 ns (VCC = 3.0–3.6 V) - supports high-speed CAN/LIN subsystem communication timing budgets |
| IOFF leakage | < ±20 μA at VCC = 0 V - prevents damaging back-current during hot-swap or partial power-down sequences |
| ESD rating | HBM > 2000 V, CDM > 1000 V - meets automotive board-level ESD immunity requirements per ISO 10605 |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood and transmission control unit environments |
| Package | TSSOP20 (SOT360-1), 4.4 mm body width - compact footprint with side-wettable flanks for AOI-compatible solder joint inspection |
Pinout & Package
TSSOP20 package (SOT360-1): 20-pin thin shrink small outline, 0.65 mm pitch, 4.4 mm body width, side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (DIR) | Direction control input | LOW = A→B data flow; HIGH = B→A data flow; critical for bidirectional CAN transceiver interface buffering |
| 2–9 (A0–A7) | Port A data I/O | Connects to microcontroller GPIO or internal bus; Schmitt-triggered for noise immunity on long PCB traces |
| 10 (GND) | Ground reference | 0 V return path; must be low-inductance connection to minimize ground bounce in high-speed switching |
| 11–18 (B0–B7) | Port B data I/O | Interfaces with external peripherals (e.g., sensor clusters); 5 V tolerant for mixed-voltage system integration |
| 19 (OE) | Output enable (active LOW) | Drives all outputs to high-Z when HIGH; enables bus sharing and hot-plug isolation in modular ECUs |
| 20 (VCC) | Supply voltage | Power rail decoupling required within 5 mm using 100 nF ceramic capacitor to suppress switching noise |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling and humidity testing |
| IOFF partial power-down | Automatically disables outputs when VCC = 0 V, eliminating risk of backfeed current in sleep-mode vehicle networks |
| 5.5 V input tolerance | Enables direct connection to 5 V LIN transceivers or legacy engine control sensors without external level shifters |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis at 3.3 V supply, rejecting noise on chassis-ground-referenced wiring in electric power steering systems |
| Bus hold (LVCH variant) | Maintains last valid logic state on floating A/B pins, eliminating need for external pull-up/down resistors in infotainment display interfaces |
Applications
| Body Control Module | Instrument Cluster Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVCH245APW-Q100 | Includes bus hold on all data inputs; identical pinout and electrical specs otherwise | Eliminates external pull resistors in high-impedance states (e.g., display interface standby mode) | Select when bus hold reduces component count and improves reliability in un-driven input scenarios |
| SN74LVC245AQPWRQ1 | Texas Instruments variant; same AEC-Q100 Grade 1 rating but different IOFF threshold and slightly higher ICC | Compatible in most automotive designs but requires validation of power-down leakage in battery-sensitive modules | Choose if TI's supply chain or existing design reuse outweighs Nexperia's side-wettable flank AOI advantage |
Compared with 74LVCH245APW-Q100, the bus hold feature adds input state retention without external components; compared with SN74LVC245AQPWRQ1, the Nexperia part offers superior manufacturability via side-wettable flanks and tighter IOFF leakage spec for ultra-low-power sleep modes.

FAQ
Is 74LVC245APW-Q100 pin-compatible with standard 74LVC245A packages?
Yes - the 74LVC245APW-Q100 uses the TSSOP20 (SOT360-1) footprint, which matches industry-standard 74LVC245A TSSOP packages. Pin numbering, signal assignment (DIR, OE, A0–A7, B0–B7, VCC, GND), and mechanical dimensions are identical, enabling drop-in replacement in existing layouts without redesign.
Does this device support hot insertion in live automotive buses?
Yes - the integrated IOFF circuit ensures outputs are disabled when VCC drops below threshold, preventing back-current flow into powered-down subsystems. This enables safe hot-plug operation in modular vehicle architectures such as replaceable ADAS camera modules or configurable gateway nodes.
What is the maximum data rate supported by this transceiver?
While not a serial interface, the device supports parallel data rates up to 100 MHz based on its worst-case propagation delay of 8.0 ns (VCC = 3.0–3.6 V, Tamb = -40 °C to +125 °C) and 1.5 ns minimum pulse width. This enables reliable operation in 100 Mbps parallel bus applications like legacy FlexRay or proprietary high-speed sensor interfaces.
How does the Schmitt-trigger input improve noise immunity in automotive environments?
Schmitt-trigger inputs provide ≥0.3 V hysteresis at 3.3 V supply, meaning the rising and falling input thresholds differ by that amount. This rejects high-frequency noise spikes and slow-rising signals induced by alternator ripple, ignition transients, or long harness runs - ensuring clean logic transitions without false triggering in body control modules.
