Texas Instruments SN74AUP1G57DRLR

Overview

SN74AUP1G57DRLR from Texas Instruments is a low-power configurable multiple-function logic gate in SOT-5X3 (DRL) package. It implements user-selectable logic functions-including AND, OR, NAND, NOR, XNOR, inverter, and noninverter-via three Schmitt-trigger inputs (In0, In1, In2) and one output (Y), operating across 0.8 V to 3.6 V supply. It delivers 5.3 ns max propagation delay at 3.3 V and supports partial-power-down mode via Ioff.

For engineers reviewing the SN74AUP1G57DRLR datasheet, SN74AUP1G57DRLR pinout, SN74AUP1G57DRLR application, or SN74AUP1G57DRLR equivalent, key selection criteria include its ultra-low ICC (0.9 μA max), 1.5 pF input capacitance, 3.6-V I/O tolerance, hysteresis-enabled noise immunity, and suitability for point-to-point signal conditioning in space-constrained portable systems.

Technical Context

The SN74AUP1G57DRLR uses CMOS AUP-family architecture optimized for battery-powered applications, featuring Schmitt-trigger inputs with programmable hysteresis (ΔVT up to 1.31 V at 3 V) to reject slow-rising or noisy signals. Its function table defines eight deterministic output states based on all combinations of the three inputs, enabling hardware-configurable logic without firmware.

It integrates Ioff circuitry that disables outputs and limits leakage to ≤0.6 μA when VCC = 0 V, supporting safe back-drive during partial power-down. The device operates reliably from –40°C to 85°C with latch-up immunity exceeding 100 mA per functional block per JESD78 Class II.

FAQ

What logic functions can the SN74AUP1G57DRLR implement?

The SN74AUP1G57DRLR implements seven configurable logic functions-AND, OR, NAND, NOR, XNOR, inverter, and noninverter-determined by the eight possible combinations of its three Schmitt-trigger inputs (In0, In1, In2). Each combination maps to a fixed output state per the function table in the datasheet; no configuration registers or programming are involved. This hardware-based configurability allows the SN74AUP1G57DRLR to replace multiple discrete gates on PCBs while maintaining deterministic timing behavior.

Does the SN74AUP1G57DRLR support partial-power-down operation?

Yes, the SN74AUP1G57DRLR supports partial-power-down operation via its Ioff feature. When VCC = 0 V, the Ioff circuitry disables all inputs and outputs, limiting leakage current to ≤0.6 μA. This prevents damaging current backflow from live I/O lines into the unpowered device-a critical requirement in modular systems with hot-swappable modules or multi-rail power sequencing. The SN74AUP1G57DRLR maintains this behavior across its full operating temperature range (–40°C to 85°C).

What is the significance of Schmitt-trigger inputs in the SN74AUP1G57DRLR?

Schmitt-trigger inputs in the SN74AUP1G57DRLR provide built-in hysteresis (ΔVT up to 1.31 V at 3 V), enabling reliable switching on slow-rising or electrically noisy signals-such as those from mechanical switches, thermistors, or unfiltered sensor outputs-without external RC networks. This eliminates false triggering caused by noise near logic thresholds and improves system robustness in harsh environments. The SN74AUP1G57DRLR's Schmitt inputs operate across its entire 0.8–3.6 V supply range, making them effective even at ultra-low voltages.

Can the SN74AUP1G57DRLR be used as a level shifter?

Yes, the SN74AUP1G57DRLR can serve as a bidirectional level shifter due to its 3.6-V I/O tolerance and wide 0.8–3.6 V VCC range. When powered at 1.2 V, its inputs accept up to 3.6 V, allowing connection to 3.3-V peripherals; outputs swing rail-to-rail within the 1.2-V domain. This eliminates the need for dedicated level-shifting ICs in mixed-voltage systems like IoT sensor nodes with 1.2-V MCUs and 3.3-V transceivers. The SN74AUP1G57DRLR achieves this without external components or direction-control pins.

What is the thermal performance of the SN74AUP1G57DRLR in its SOT-5X3 package?

The SN74AUP1G57DRLR in the SOT-5X3 (DRL) package has a junction-to-ambient thermal resistance (RθJA) of 142°C/W, measured per JEDEC JESD51 standards. This value reflects its ability to dissipate heat in still-air conditions on a standard 2-layer PCB with moderate copper area. Given its ultra-low power consumption (ICC ≤ 0.9 μA), self-heating is negligible-even at maximum ambient temperature (85°C)-ensuring stable timing and logic behavior without thermal derating. No heatsink or forced airflow is required for typical applications.
