Nexperia USA Inc. 74LVC1G57GM,115

Overview

74LVC1G57GM,115 from Nexperia is a single-channel configurable logic gate with Schmitt-trigger inputs, supporting AND, OR, NAND, NOR, XNOR, inverter, and buffer configurations via 3-bit input selection. It operates from 1.65 V to 5.5 V, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and is rated for -40 °C to +125 °C. It enables voltage-level translation between 3.3 V and 5 V subsystems in compact portable electronics.

For engineers reviewing the 74LVC1G57GM,115 datasheet, 74LVC1G57GM,115 pinout, 74LVC1G57GM,115 application, or 74LVC1G57GM,115 equivalent, key selection criteria include its reconfigurable logic function, Schmitt-trigger noise immunity, IOFF-enabled mixed-voltage system integration, and XSON6 package suitability for space-constrained PCB layouts.

Technical Context

This device implements a single configurable logic cell using CMOS technology with three data inputs (A, B, C), one output (Y), and dual-rail supply (VCC/GND). Its internal architecture maps the 3-bit input combination directly to one of seven standard logic functions without external configuration circuitry or clocking.

The Schmitt-trigger input stage provides hysteresis (e.g., 0.48 V typical at VCC = 1.8 V), enabling robust noise rejection in noisy environments. The IOFF circuit actively disables output leakage when VCC = 0 V, preventing backflow current during partial power-down - critical for hot-swap and multi-rail power sequencing.

FAQ

Can the 74LVC1G57GM,115 be used as a level translator between 5 V and 1.8 V domains?

Yes - its inputs tolerate up to 5.5 V regardless of VCC, and its output swings rail-to-rail between GND and VCC. When powered at 1.8 V, it accepts 5 V inputs and outputs 0 V / 1.8 V logic levels, satisfying I_OH/I_OL requirements for driving 1.8 V CMOS loads with ±24 mA drive capability at 3.0 V (derated at 1.8 V).

What is the minimum input rise/fall time supported without causing metastability?

The device has no clock or internal state, so metastability does not apply. However, the Schmitt-trigger input requires monotonic transitions. Data sheet specifies t_r/t_f ≤ 2.5 ns for valid switching at VCC ≥ 3.0 V. Slower edges (e.g., >100 ns) are acceptable if within the hysteresis window - verified by transfer characteristic curves showing clean transitions down to 10 μs.

Does the IOFF feature work when only GND is connected and VCC is floating?

No - IOFF activation requires VCC = 0 V (actively pulled to ground), not floating. If VCC is left unconnected, internal protection diodes may forward-bias, allowing unintended current flow. For true isolation, VCC must be hard-grounded during power-down, as confirmed in Section 1 of the datasheet under "partial power down applications using IOFF".

How is the logic function selected - is it programmable or hardwired per application?

The logic function is statically selected by the DC voltage levels applied to pins A, B, and C at power-up or runtime - no programming interface or non-volatile memory is involved. Table 4 defines the exact Y output for each of the eight (2³) A/B/C combinations, enabling real-time reconfiguration by driving those inputs from GPIOs or fixed resistors.
