Nexperia USA Inc. 74AUP1T57GW,125

Overview

74AUP1T57GW,125 from Nexperia is a single-supply, low-power configurable logic gate with Schmitt-trigger inputs and voltage-level translation capability, supporting AND/OR/NAND/NOR/XNOR/inverter/buffer configurations via 3-bit input selection. It operates from 2.3 V to 3.6 V, delivers ≤1.5 μA max ICC, features IOFF partial power-down protection, and is housed in a TSSOP6 (SOT363-2) package rated for −40 °C to +125 °C. It enables level-shifting between 1.8 V and 3.3 V domains in portable sensor interfaces.

For engineers reviewing the 74AUP1T57GW,125 datasheet, 74AUP1T57GW,125 pinout, 74AUP1T57GW,125 application, or 74AUP1T57GW,125 equivalent, this device serves as a space-constrained, ultra-low-power logic configurator for mixed-voltage I/O bridging in battery-powered IoT nodes, industrial control signal conditioning, and FPGA/CPLD glue logic where static current and noise immunity are critical.

Technical Context

The 74AUP1T57GW,125 implements a programmable combinational logic function using three input pins (A, B, C) to select one of seven standard logic operations via internal truth table mapping. Its Schmitt-trigger inputs provide hysteresis (0.15–0.56 V) for robust noise rejection in noisy environments.

It supports true voltage-level translation: inputs tolerate up to 3.6 V regardless of VCC (2.3–3.6 V), enabling 1.8 V logic to drive a 3.3 V system rail without external level shifters. The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

FAQ

What logic functions can the 74AUP1T57GW,125 implement, and how are they selected?

The 74AUP1T57GW,125 implements AND, OR, NAND, NOR, XNOR, inverter, and buffer functions by hardwiring its three input pins (A, B, C) to VCC or GND according to Table 4 and Figure 2–8 in the datasheet. No external programming or clock is needed - configuration is static and determined at power-up by the DC voltage levels applied to A, B, and C. Each combination maps directly to a specific truth table output Y.

Does the 74AUP1T57GW,125 support true bidirectional level translation?

No - the 74AUP1T57GW,125 supports unidirectional level translation only: inputs accept 0–3.6 V logic levels independent of VCC (2.3–3.6 V), but the output Y swings between 0 V and VCC. It cannot translate from a higher voltage domain to a lower one on the output side. For bidirectional translation, a dedicated bus switch or dual-supply translator is required.

How does the IOFF feature behave during power-down, and what is its leakage specification?

When VCC = 0 V, the IOFF circuit forces the output Y into high-impedance state, blocking current flow in either direction. Measured IOFF leakage is ±0.75 μA maximum at −40 °C to +125 °C with VI or VO biased from 0 V to 3.6 V, ensuring safe isolation during hot-swap or partial system shutdown without external pull resistors.

Can the 74AUP1T57GW,125 be used in a 1.8 V-only system?

No - the minimum VCC is 2.3 V per Table 7. While inputs tolerate 1.8 V logic levels (enabling interfacing with 1.8 V drivers), the device itself requires ≥2.3 V on VCC to operate correctly. Attempting to power it at 1.8 V will result in undefined output behavior and failure to meet timing or logic specifications.
