Texas Instruments SN74AUP1G98DCKT

Overview

SN74AUP1G98DCKT from Texas Instruments is a low-power configurable multiple-function logic gate in SC-70 (DCK) package with 6 pins. It operates across 0.8 V to 3.6 V supply, delivers 5.3 ns max propagation delay at 3.3 V, features Schmitt-trigger inputs for noise immunity, and supports eight logic configurations (MUX, AND, OR, NAND, NOR, inverter, noninverter) via three input control bits - ideal for space-constrained battery-powered sensor interfaces and portable I/O expansion.

For engineers reviewing the SN74AUP1G98DCKT datasheet, SN74AUP1G98DCKT pinout, SN74AUP1G98DCKT application, or SN74AUP1G98DCKT equivalent, key selection criteria include its ultra-low ICC (0.9 mA max), 1.5 pF typical input capacitance, Ioff partial-power-down support, 3.6-V I/O tolerance for mixed-voltage systems, and verified compatibility with SC-70 PCB footprints per TI's DCK0006A mechanical drawing.

Technical Context

The SN74AUP1G98DCKT implements a single configurable logic cell with three independent inputs (A, B, C) and one output (Y), where the function is selected by the 3-bit combination of CBA per the documented function table. Its Schmitt-trigger inputs provide hysteresis (ΔVT up to 1.31 V at 3 V), enabling robust operation with slow-rising signals and high noise margin.

It uses TI's AUP (Advanced Ultra-Low-Power) process, optimized for sub-1-V operation down to 0.8 V while maintaining full logic functionality and rail-to-rail output swing. The Ioff circuitry actively disables outputs during power-down, preventing back-current flow when VCC = 0 V - critical for hot-swap and multi-rail system integrity.

FAQ

What logic functions does the SN74AUP1G98DCKT support?

The SN74AUP1G98DCKT supports eight configurable logic functions: 2-to-1 data selector with inverted output, 2-input NAND, 2-input NOR with one inverted input, 2-input AND with one inverted input, 2-input NAND with one inverted input, 2-input OR with one inverted input, 2-input NOR, noninverted buffer, and inverter - all selected via the CBA input combination per the function table in the SCES506H datasheet. Each mode is statically defined and latched on power-up or input change.

Does the SN74AUP1G98DCKT require external pull-up or pull-down resistors on unused inputs?

No - all unused inputs of the SN74AUP1G98DCKT must be held at VCC or GND to ensure proper device operation, as specified in TI's recommended operating conditions. Floating inputs are prohibited because they can cause excessive ICC, unpredictable output states, or increased EMI susceptibility. Direct connection to supply or ground is mandatory; external resistors are unnecessary and add parasitic capacitance.

Can the SN74AUP1G98DCKT operate reliably at 0.8 V supply?

Yes - the SN74AUP1G98DCKT is fully specified from 0.8 V to 3.6 V. At 0.8 V, it maintains functional logic operation with tpd ≤22.2 ns (CL = 5 pF) and ICC ≤0.5 mA, enabling integration into energy-harvesting or ultra-low-power systems where traditional logic families fail. Performance metrics at 0.8 V are explicitly validated in the Electrical Characteristics and Switching Characteristics tables of the SCES506H datasheet.

Is the SN74AUP1G98DCKT pin-compatible with other SC-70 logic devices?

The SN74AUP1G98DCKT uses the standard SC-70-6 (DCK) footprint per TI's DCK0006A mechanical drawing, matching pin 1 location, pad dimensions, and pitch (0.65 mm). However, pin function mapping (A, B, C, Y, VCC, GND) is unique to this configurable gate - it is not pin-compatible with fixed-function SC-70 logic gates like SN74AUP1G08 or SN74LVC1G04, which assign different signals to pins 1, 3, 5, and 6.

What is the maximum capacitive load the SN74AUP1G98DCKT output can drive?

The SN74AUP1G98DCKT output is characterized up to 30 pF load capacitance in the Switching Characteristics tables, with tpd increasing predictably (e.g., 8.3 ns max at 3.3 V, CL = 15 pF). Driving >30 pF may exceed timing specifications and increase dynamic power; for heavier loads, TI recommends buffering with a dedicated driver or using the device in lower-speed configurations with appropriate slew-rate control.
