Nexperia USA Inc. 74LVC1G57GV-Q100H

Overview

74LVC1G57GV-Q100 from Nexperia is a single-channel, automotive-grade configurable logic gate with Schmitt-trigger inputs, supporting AND/OR/NAND/NOR/XNOR/inverter/buffer configurations via 3-bit input selection. 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 between mixed-voltage sensor interfaces.

For engineers reviewing the 74LVC1G57GV-Q100 datasheet, 74LVC1G57GV-Q100 pinout, 74LVC1G57GV-Q100 application, or 74LVC1G57GV-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, Schmitt-trigger noise immunity, 6-pin SC-74 (SOT457) package, and configurable logic function mapping across temperature range −40 °C to +125 °C.

Technical Context

This device implements a 3-input programmable logic cell where inputs A, B, and C determine the Boolean function applied to generate output Y. Its Schmitt-trigger inputs provide hysteresis (e.g., 0.48 V typical at VCC = 1.8 V), enabling robust noise rejection in electrically noisy automotive environments.

The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V - critical for hot-swap and partial-power-down systems. Input voltage tolerance up to 5.5 V allows direct interfacing with both 3.3 V and 5 V logic families without level shifters.

FAQ

What logic functions can the 74LVC1G57GV-Q100 implement?

The device supports seven configurable logic functions - AND, OR, NAND, NOR, XNOR, inverter, and buffer - selected by applying HIGH/LOW states to its three inputs (A, B, C). The function table in section 7 of the datasheet defines exact input combinations for each mode, with no external programming required.

Does the 74LVC1G57GV-Q100 support mixed-voltage operation?

Yes. Its inputs tolerate up to 5.5 V regardless of VCC level (1.65 V–5.5 V), allowing direct interfacing with 5 V TTL or CMOS devices while powering from 3.3 V or 2.5 V rails. This eliminates external level shifters in mixed-voltage automotive subsystems.

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

When VCC = 0 V, the IOFF circuit places the output (Y) in high-impedance state, blocking current flow from other powered devices on the same bus. Measured IOFF leakage is ≤±2 μA, preventing backfeed damage and ensuring safe partial power-down in multi-supply automotive ECUs.

Is the 74LVC1G57GV-Q100 pin-compatible with other SOT457 logic gates?

No. While it shares the SOT457 (SC-74) 6-pin footprint with other Nexperia single-gate devices like 74LVC1G00 or 74LVC1G08, pin assignments differ: 74LVC1G57GV-Q100 uses pins 1/3/6 for configuration inputs (B/A/C), pin 4 for output (Y), and pin 5 for VCC - incompatible with standard gate pinouts.
