Texas Instruments SN74AUP1G57DRLRG4

Overview

SN74AUP1G57DRLRG4 from Texas Instruments is a low-power configurable multiple-function logic gate with Schmitt-trigger inputs, operating across 0.8 V to 3.6 V supply range, delivering 5.3 ns max propagation delay at 3.3 V, 4.3 pF typical dynamic power capacitance, and 0.9 μA max static current - used in point-to-point signal conditioning for portable medical and consumer electronics.

For engineers reviewing the SN74AUP1G57DRLRG4 datasheet, SN74AUP1G57DRLRG4 pinout, SN74AUP1G57DRLRG4 application, or SN74AUP1G57DRLRG4 equivalent, key selection criteria include Ioff-enabled partial-power-down operation, 3.6-V I/O tolerance for mixed-voltage interfacing, hysteresis-enabled noise immunity, and support for AND/OR/NAND/NOR/XNOR/inverter/noninverter logic configuration via three input pins.

Technical Context

The SN74AUP1G57DRLRG4 implements a single-gate logic function determined by all eight combinations of its three inputs (In0–In2), enabling user-selectable Boolean operations without external programming. Its Schmitt-trigger inputs provide 0.18–1.31 V hysteresis (ΔVT) across VCC = 0.8–3.0 V, ensuring robust switching against slow-rising or noisy signals.

It features Ioff circuitry that disables outputs and limits leakage to ≤0.6 μA when VCC = 0 V, supporting safe back-drive prevention in partial-power-down systems. The device uses CMOS technology with balanced output drive, rated for ±20 mA output current and compliant with JESD 78 Class II latch-up performance (>100 mA).

FAQ

What logic functions does the SN74AUP1G57DRLRG4 support?

The SN74AUP1G57DRLRG4 supports seven configurable logic functions - AND, OR, NAND, NOR, XNOR, inverter, and noninverter - selected by the eight possible combinations of its three inputs (In0, In1, In2). Each configuration is defined in the device's function table (Table 1) and verified across the full –40°C to 85°C operating range. No external configuration pins or programming are required - logic mode is set solely by static input states.

Does SN74AUP1G57DRLRG4 support partial-power-down operation?

Yes, SN74AUP1G57DRLRG4 includes Ioff circuitry that disables outputs and limits input/output leakage to ≤0.6 μA when VCC = 0 V. This feature prevents damaging current backflow in multi-rail systems during power sequencing or hot-swap events. The Ioff specification is tested per JESD78 and applies across –40°C to 85°C, making SN74AUP1G57DRLRG4 suitable for battery-backed subsystems and modular industrial controllers.

What is the maximum propagation delay of SN74AUP1G57DRLRG4 at 3.3 V?

The maximum propagation delay (tpd) of SN74AUP1G57DRLRG4 is 5.3 ns at VCC = 3.3 V with CL = 5 pF, measured from any input (In0, In1, or In2) to output Y. This value is guaranteed over the full operating temperature range (–40°C to 85°C) and includes both tPLH and tPHL. At higher capacitive loads (e.g., 30 pF), tpd increases to 8.4 ns - a predictable trade-off documented in Section 6.9 of the datasheet.

Can SN74AUP1G57DRLRG4 interface between 1.2-V and 3.3-V logic domains?

Yes, SN74AUP1G57DRLRG4 supports mixed-mode signal operation due to its 3.6-V I/O tolerance and wide VCC range (0.8 V to 3.6 V). Inputs accept voltages up to 4.6 V regardless of VCC, allowing direct connection to 3.3-V drivers while powered from a 1.2-V rail. Outputs swing rail-to-rail (VOL ≤ 0.1 V, VOH ≥ VCC – 0.1 V), enabling reliable interfacing with downstream 1.2-V or 3.3-V receivers without external level shifters.

What package type is used for SN74AUP1G57DRLRG4?

SN74AUP1G57DRLRG4 uses the SON (Small Outline No-lead) package designated DRY - a 6-pin, 1.00 mm × 1.45 mm body with 0.5-mm pitch and wettable flanks for automated optical inspection. This package is distinct from the SOT-23 (DBV) and SC70 (DCK) variants and is specified in TI's orderable addendum with MSL Level-1 rating and NIPDAU lead finish.
