Texas Instruments SN74AUP1G57YZPR

Overview

SN74AUP1G57YZPR from Texas Instruments is a low-power configurable multiple-function logic gate in a 6-pin DSBGA package (1.388 × 0.888 mm), supporting AND, OR, NAND, NOR, XNOR, inverter, and noninverter functions via three Schmitt-trigger inputs (In0–In2) and one output (Y). It operates across 0.8 V to 3.6 V, delivers 5.3 ns max propagation delay at 3.3 V, and draws only 0.9 μA max ICC - ideal for battery-powered portable electronics requiring flexible single-gate logic.

For engineers reviewing the SN74AUP1G57YZPR datasheet, SN74AUP1G57YZPR pinout, SN74AUP1G57YZPR application, or SN74AUP1G57YZPR equivalent, key selection criteria include its Ioff-enabled partial-power-down capability, 1.5 pF typical input capacitance, 3.6-V I/O tolerance for mixed-voltage interfacing, and support for point-to-point signal conditioning in space-constrained designs.

Technical Context

The SN74AUP1G57YZPR implements a 3-input lookup table architecture where all eight possible combinations of In2/In1/In0 determine Y's logic state per the function table. Its Schmitt-trigger inputs provide hysteresis (ΔVT up to 1.31 V at 3 V), enabling robust noise immunity and reliable operation with slow-rising signals.

It features Ioff circuitry that disables outputs and limits leakage to ≤0.6 μA when VCC = 0 V, allowing safe back-driving in partial-power-down systems. The device is optimized for 3.3-V operation but maintains full functionality down to 0.8 V, with output drive strength scaling from ±20 μA (0.8 V) to ±4 mA (3 V).

FAQ

What logic functions does SN74AUP1G57YZPR support?

SN74AUP1G57YZPR supports seven configurable logic functions - AND, OR, NAND, NOR, XNOR, inverter, and noninverter - selected by the eight possible combinations of its three Schmitt-trigger inputs (In2, In1, In0). Each combination maps directly to a defined output state per the function table in the datasheet, enabling flexible gate reuse without changing hardware.

Does SN74AUP1G57YZPR require external pull-up or pull-down resistors?

No, SN74AUP1G57YZPR does not require external pull-up or pull-down resistors. All inputs can be directly tied to VCC or GND to configure logic functions, and the device's Schmitt-trigger inputs ensure stable logic levels even with slow transitions. Unused inputs must be held at VCC or GND per TI's SCBA004 guidance to prevent floating node issues.

Can SN74AUP1G57YZPR operate at 1.2 V supply voltage?

Yes, SN74AUP1G57YZPR is fully specified for operation at 1.2 V supply voltage. At VCC = 1.2 V, it delivers typical propagation delay of 9.5 ns (CL = 5 pF), VIH of 0.75 × VCC, and ICC of ≤0.9 μA - making it compatible with modern ultra-low-voltage microcontrollers and sensors in energy-harvesting and wearable applications.

What is the thermal resistance (RθJA) of SN74AUP1G57YZPR in its YZP package?

The junction-to-ambient thermal resistance (RθJA) of SN74AUP1G57YZPR in the DSBGA (YZP) package is 123°C/W, as specified in the Thermal Information table. This value assumes standard JEDEC JESD51-2 PCB mounting conditions and confirms suitability for thermally constrained environments such as sealed medical enclosures or stacked PCB assemblies.

How does the Ioff feature of SN74AUP1G57YZPR benefit system design?

The Ioff feature of SN74AUP1G57YZPR limits leakage current to ≤0.6 μA when VCC = 0 V, preventing damaging back-current flow through the device during partial power-down or hot-swap events. This enables safe integration into multi-rail systems like portable diagnostic equipment where subsystems power up/down independently without risking latch-up or data corruption.
