Nexperia USA Inc. 74LVC1G57GV,125

Overview

74LVC1G57GV,125 from Nexperia is a single-channel configurable logic gate with Schmitt-trigger inputs, supporting AND, OR, NAND, NOR, XNOR, inverter, and buffer configurations via its 3-bit input select (A/B/C). 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 voltage-level translation between 3.3 V and 5 V subsystems in industrial control I/O interfaces.

For engineers reviewing the 74LVC1G57GV,125 datasheet, 74LVC1G57GV,125 pinout, 74LVC1G57GV,125 application, or 74LVC1G57GV,125 equivalent, key selection criteria include configurable logic function mapping, Schmitt-trigger noise immunity, IOFF-enabled mixed-voltage system isolation, and SC-74 (SOT457) package compatibility with space-constrained PCB layouts.

Technical Context

The device implements a programmable logic cell using three data inputs (A, B, C) to select one of seven standard Boolean functions, with all inputs internally terminated to support direct connection to VCC or GND. Its Schmitt-trigger inputs provide hysteresis (e.g., 0.48 V typical at VCC = 1.8 V), enabling robust noise rejection in noisy industrial environments.

IOFF circuitry disables output drivers when VCC = 0 V, blocking backflow current during partial power-down - critical for hot-swap and multi-rail systems. Input overvoltage tolerance up to 5.5 V allows safe interfacing with 5 V TTL outputs while powered from 1.8 V or 3.3 V rails.

FAQ

What logic functions can be implemented with the 74LVC1G57GV,125?

The 74LVC1G57GV,125 supports seven logic functions: AND, OR, NAND, NOR, XNOR, inverter, and buffer. These are selected by applying specific HIGH/LOW combinations to its three inputs (A, B, C) as defined in Table 4 of the datasheet. No external programming or clock is needed - configuration is static and immediate upon input state settling.

Does the 74LVC1G57GV,125 require external pull-up or pull-down resistors on its inputs?

No. All inputs (A, B, C) can be directly tied to VCC or GND without external resistors. The device's internal design allows hard-wired logic configuration, eliminating BOM overhead and board space for discrete biasing components - confirmed in Section 1 General Description and Table 4 Function Table.

How does the IOFF feature behave during power sequencing?

When VCC drops to 0 V, the IOFF circuit automatically disables the output driver (Y), placing it in high-impedance state and limiting leakage current to ±2 μA maximum. This prevents reverse current flow from other powered rails through the output, protecting both the 74LVC1G57GV,125 and connected devices during staggered power-up/down - specified in Section 1 and Table 8 Limiting Values.

Can the 74LVC1G57GV,125 be used in automotive under-hood applications?

While rated for -40 °C to +125 °C, the 74LVC1G57GV,125 is not AEC-Q100 qualified and is explicitly designated as non-automotive by Nexperia. It may be used in non-safety-critical under-hood subsystems only after full customer validation, but carries no automotive warranty or qualification assurance per Nexperia's legal disclaimers.
