Texas Instruments SN74LVC1G97YZPRB

Overview

SN74LVC1G97YZPRB from Texas Instruments is a configurable single-gate logic IC supporting nine logic functions-including 2-to-1 MUX, AND, OR, NAND, NOR, inverter, and noninverting buffer-via three input select lines (In2, In1, In0). It operates from 1.65 V to 5.5 V, delivers ±24 mA output drive at 3.3 V, and achieves 6.3 ns max propagation delay. It is used in space-constrained digital control interfaces requiring reconfigurable logic without redesign.

For engineers reviewing the SN74LVC1G97YZPRB datasheet, SN74LVC1G97YZPRB pinout, SN74LVC1G97YZPRB application, or SN74LVC1G97YZPRB equivalent, key selection criteria include its 3-input function selection capability, Ioff support for partial-power-down mode, Schmitt-trigger hysteresis (0.53–1.11 V), 6-pin WCSP package footprint, and compatibility with mixed-voltage systems up to 5.5 V on inputs.

Technical Context

This device implements a 3-bit programmable logic cell where the output Y is determined by eight possible combinations of In2/In1/In0, enabling dynamic configuration of logic behavior without external components. Its internal architecture includes Schmitt-trigger inputs (VT+ = 1.5–2.74 V, VT– = 0.84–2.29 V at 3–5.5 V) and Ioff circuitry that disables outputs during power-down to prevent backflow current.

It supports voltage translation across 1.65–5.5 V supply rails, accepts input voltages up to 5.5 V independent of VCC, and maintains rail-to-rail output swing. The logic function mapping is fixed per the function table-not user-programmable via serial interface-and all unused inputs must be tied to VCC or GND for stable operation.

FAQ

What logic functions does the SN74LVC1G97YZPRB support?

The SN74LVC1G97YZPRB supports nine logic functions determined by the In2/In1/In0 input combination: 2-to-1 data selector, 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. These are fixed mappings defined in the function table-not programmable via software-and require no external configuration circuitry.

Does the SN74LVC1G97YZPRB support partial power-down operation?

Yes, the SN74LVC1G97YZPRB includes Ioff circuitry that disables outputs when VCC = 0 V, limiting Ioff to ±10 µA maximum. This prevents damaging current backflow from live inputs into a powered-down system domain-a critical feature for hot-swap and multi-rail architectures. The SN74LVC1G97YZPRB maintains this behavior across its full –40°C to 85°C operating temperature range.

What is the significance of Schmitt-trigger inputs on the SN74LVC1G97YZPRB?

The SN74LVC1G97YZPRB features Schmitt-trigger inputs with hysteresis (∆VT = 0.53–1.11 V depending on VCC), providing distinct positive-going (VT+) and negative-going (VT–) thresholds. This enables reliable switching on slow-rising or electrically noisy signals-such as mechanical switch debouncing or long PCB trace inputs-without external RC networks, directly improving system robustness in industrial environments.

Can the SN74LVC1G97YZPRB operate with a 1.8-V supply and accept 3.3-V inputs?

Yes, the SN74LVC1G97YZPRB operates from 1.65 V to 5.5 V and accepts input voltages up to 5.5 V regardless of VCC level. When powered at 1.8 V, it safely interfaces with 3.3-V or 5-V signal sources without level shifters-enabling seamless voltage translation in mixed-supply systems. All electrical parameters, including tpd and output drive, are guaranteed across this full VCC and VI range.

What package type and dimensions does the SN74LVC1G97YZPRB use?

The SN74LVC1G97YZPRB uses the NanoFree™ WCSP (YZP) package: a 6-bump, Pb-free wafer-chip-scale package measuring 1.0 mm × 1.0 mm × 0.55 mm with 0.23-mm large solder bumps. Pin 1 is marked with a dot on the bottom side. This package eliminates leads and substrate, delivering the smallest possible footprint for a 6-terminal logic gate-ideal for ultra-compact applications like hearing aids and wearable sensors.
