Nexperia USA Inc. 74LVC1G57GW-Q100H

Overview

74LVC1G57GW-Q100 from Nexperia is an automotive-grade configurable logic gate with Schmitt-trigger inputs, supporting AND, OR, NAND, NOR, XNOR, inverter, and buffer functions via 3-bit configuration (A/B/C inputs). It operates from 1.65 V to 5.5 V, tolerates 5.5 V inputs, delivers ±24 mA output drive at 3.0 V, and features IOFF partial power-down protection. It is used in automotive body control modules for signal conditioning of noisy sensor inputs.

For engineers reviewing the 74LVC1G57GW-Q100 datasheet, 74LVC1G57GW-Q100 pinout, 74LVC1G57GW-Q100 application, or 74LVC1G57GW-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, Schmitt-trigger noise immunity, mixed-voltage translation capability (3.3 V/5 V), and TSSOP6 package compatibility with space-constrained automotive PCB layouts.

Technical Context

This device implements a single configurable logic cell using CMOS technology with Schmitt-trigger input thresholds (VT+ = 1.50 V, VT− = 0.80 V at VCC = 3.0 V) and hysteresis (VH = 0.75 V), enabling robust operation in electrically noisy automotive environments. Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V.

The 3-input configuration (A, B, C) selects one of seven logic functions without external programming-function mapping is hardwired per truth table (e.g., CBA = 000 → Y = HIGH; CBA = 001 → Y = LOW). Propagation delay ranges from 0.5 ns (min) to 7.9 ns (max) at VCC = 3.0–3.6 V, with CPD = 22 pF defining dynamic power consumption.

FAQ

What logic functions can the 74LVC1G57GW-Q100 implement?

The device implements seven logic functions-AND, OR, NAND, NOR, XNOR, inverter, and buffer-determined solely by the DC voltage levels applied to its three configuration inputs (A, B, C). No clock, programming interface, or external memory is required; function selection is static and immediate upon power-up.

How does the IOFF feature protect the device during partial power-down?

When VCC drops to 0 V, the IOFF circuit disables both output pull-up and pull-down transistors, isolating the Y output from the internal logic. This limits backflow current to ±2 μA maximum, preventing damage to upstream drivers or unintended activation of downstream loads during power sequencing.

Can the 74LVC1G57GW-Q100 interface between 3.3 V and 5 V systems?

Yes. Its inputs tolerate up to 5.5 V regardless of VCC setting (1.65–5.5 V), and its output swings rail-to-rail. When VCC = 3.3 V, it accepts 5 V inputs safely; when VCC = 5 V, it drives 5 V logic levels - enabling bidirectional voltage translation without external components.

Is the Schmitt-trigger input behavior configurable or fixed?

The Schmitt-trigger input behavior is fixed and inherent to all three inputs (A, B, C); it cannot be disabled. Thresholds (VT+, VT−) and hysteresis (VH) are process-defined and vary with VCC - e.g., VH = 0.75 V at VCC = 3.0 V - providing consistent noise immunity across operating conditions.
