Nexperia USA Inc. 74LVC1G57GW,125

Overview

74LVC1G57GW,125 from Nexperia is a single configurable multiple-function 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, and features IOFF partial power-down protection. It enables level translation between 3.3 V and 5 V systems in compact TSSOP6 packaging.

For engineers reviewing the 74LVC1G57GW,125 datasheet, 74LVC1G57GW,125 pinout, 74LVC1G57GW,125 application, or 74LVC1G57GW,125 equivalent, this device serves as a space-optimized, voltage-flexible logic configurator for mixed-supply interface, noise-immune signal conditioning, and low-power reconfigurable gate deployment in industrial control and portable electronics.

Technical Context

The 74LVC1G57GW implements a 3-input (A/B/C), 1-output (Y) combinational logic block with Schmitt-trigger inputs enabling robust noise rejection on asynchronous signals. Its function is determined by the static logic state of inputs A, B, and C per the defined truth table - no internal configuration register or clock required.

IOFF circuitry actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down. Inputs tolerate up to 5.5 V regardless of VCC, allowing direct interfacing with both 3.3 V and 5 V drivers without external level shifters.

FAQ

Can the 74LVC1G57GW,125 be used as a level shifter between 5 V and 3.3 V logic?

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 3.3 V with 5 V inputs, it reliably translates high-voltage signals to 3.3 V logic levels without external components - confirmed by JEDEC JESD8-5 compliance and 5.5 V input rating.

What logic functions does the 74LVC1G57GW,125 support, and how are they selected?

It supports seven functions: AND, OR, NAND, NOR, XNOR, inverter, and buffer. Selection is determined solely by the DC logic states of its three inputs (A, B, C) per the documented truth table - no programming interface or clock required. Each combination maps directly to one function, e.g., A=L, B=L, C=L yields Y=H (AND).

Does the 74LVC1G57GW,125 support partial power-down, and how does it behave when VCC = 0 V?

Yes. Its IOFF circuitry disables the output when VCC = 0 V, limiting output leakage to ±2 μA maximum. This prevents back-current flow from live inputs or outputs into the unpowered device - critical for hot-swap systems and multi-rail boards where subsystems power up/down asynchronously.

Is the Schmitt-trigger input hysteresis adjustable, and what is its typical value?

No, hysteresis is fixed and process-defined. At VCC = 2.3 V, typical hysteresis (VT+ − VT−) is 0.48 V, with VT+ = 1.42 V and VT− = 0.94 V. This provides consistent noise margin across temperature and supply voltage, eliminating need for external hysteresis components in slow-switching applications like pushbutton debouncing.
