Texas Instruments SN74AUP1G97DCKTG4

Overview

SN74AUP1G97DCKTG4 from Texas Instruments is a low-power configurable multiple-function logic gate in SC-70 (DCK) package with 6 pins. It implements eight logic functions-including MUX, AND, OR, NAND, NOR, inverter, and noninverter-via three input control bits (A, B, C), features Schmitt-trigger inputs for noise immunity, operates from 0.8 V to 3.6 V, and delivers 5.6 ns max propagation delay at 3.3 V. It is used in battery-powered portable devices requiring flexible logic configuration with minimal power draw.

For engineers reviewing the SN74AUP1G97DCKTG4 datasheet, SN74AUP1G97DCKTG4 pinout, SN74AUP1G97DCKTG4 application, or SN74AUP1G97DCKTG4 equivalent, key selection criteria include its wide VCC range (0.8–3.6 V), Ioff support for partial-power-down mode, 1.5 pF typical input capacitance, Schmitt-trigger hysteresis (0.79 V min at 3 V), and compatibility with mixed-mode signal operation due to 3.6-V I/O tolerance.

Technical Context

The SN74AUP1G97DCKTG4 uses a 3-bit function-select architecture where inputs A, B, and C determine output Y's logic behavior per the defined function table. Its Schmitt-trigger inputs provide hysteresis (ΔVT = 0.79 V min at VCC = 3 V), enabling robust operation with slow-rising signals and improved noise rejection.

It supports partial-power-down via Ioff circuitry that disables outputs when VCC = 0 V, preventing backflow current. The device maintains low dynamic power (Cpd = 4.8 pF typ at 3.3 V) and static current (ICC ≤ 0.9 mA max across full VCC range), making it suitable for point-to-point interconnects in space-constrained, ultra-low-power systems.

FAQ

What logic functions does the SN74AUP1G97DCKTG4 support?

The SN74AUP1G97DCKTG4 supports eight configurable logic functions determined by the 3-bit input combination on pins A, B, and C: 2-to-1 data selector (MUX), 2-input AND, 2-input OR with one inverted input, 2-input NAND with one inverted input, 2-input AND with one inverted input, 2-input NOR with one inverted input, 2-input OR, inverter, and noninverted buffer. Each function is explicitly defined in the datasheet's Function Selection Table and verified across the full operating temperature range.

Does the SN74AUP1G97DCKTG4 support partial-power-down operation?

Yes, the SN74AUP1G97DCKTG4 includes Ioff circuitry that actively disables outputs when VCC = 0 V, preventing current backflow from live I/O lines into the unpowered device. This feature is fully characterized per JESD 78 Class II latch-up testing and supports safe hot-swap and multi-rail power sequencing - a key requirement in modern portable and modular electronics designs using SN74AUP1G97DCKTG4.

What is the maximum propagation delay of the SN74AUP1G97DCKTG4 at 3.3 V?

The maximum propagation delay (tpd) of the SN74AUP1G97DCKTG4 is 5.6 ns at VCC = 3.3 V ± 0.3 V, CL = 5 pF, and TA = –40°C to 85°C. This value is measured from any input (A, B, or C) to output Y under worst-case process/voltage/temperature conditions and is guaranteed by TI's production test flow - ensuring timing predictability in high-speed digital signal paths using SN74AUP1G97DCKTG4.

Is the SN74AUP1G97DCKTG4 compatible with 1.8-V and 3.3-V systems?

Yes, the SN74AUP1G97DCKTG4 operates across a continuous VCC range of 0.8 V to 3.6 V and features 3.6-V tolerant I/Os. It functions reliably at 1.8 V (with tpd ≤ 9.4 ns, CL = 5 pF) and 3.3 V (tpd ≤ 5.6 ns), and its inputs accept voltages up to 3.6 V regardless of VCC level - enabling seamless integration in mixed-voltage systems such as those combining 1.8-V MCUs with 3.3-V peripherals using SN74AUP1G97DCKTG4.

What package type and dimensions does the SN74AUP1G97DCKTG4 use?

The SN74AUP1G97DCKTG4 uses the SC-70 (DCK) package: a 6-pin surface-mount outline measuring 2.0 mm × 1.25 mm × 0.9 mm (max height), with pin pitch of 0.65 mm. It is RoHS-compliant, lead-finish NIPDAU, and rated MSL Level-1 (unlimited floor life at ≤30°C/60% RH). This compact footprint is ideal for space-constrained PCBs in wearables and IoT edge nodes deploying SN74AUP1G97DCKTG4.
