Texas Instruments SN74LVC1G97YZAR

Overview

SN74LVC1G97YZAR from Texas Instruments is a configurable single-gate logic IC supporting nine programmable functions-including AND, OR, NAND, NOR, inverter, noninverter, and 2-to-1 multiplexer-via three digital inputs (In0–In2), with Schmitt-trigger inputs enabling noise-immune signal conditioning in industrial sensor interfaces and power sequencing circuits.

For engineers reviewing the SN74LVC1G97YZAR datasheet, SN74LVC1G97YZAR pinout, SN74LVC1G97YZAR application, or SN74LVC1G97YZAR equivalent, this device offers flexible logic configuration in ultra-small DSBGA packaging, Ioff-enabled partial-power-down capability, 1.65–5.5-V operation, ±24-mA drive at 3.3 V, and 6.3-ns max propagation delay-critical for space-constrained, low-power embedded control and interface translation designs.

Technical Context

The SN74LVC1G97YZAR implements a 3-input configurable logic gate with Schmitt-trigger input thresholds (VT+ = 1.5–2.74 V, VT– = 0.84–1.9 V at 3–4.5 V VCC) to reject noise on slow or noisy signals. Its function selection is determined by all eight combinations of In0/In1/In2, enabling static configuration without external programming circuitry.

It supports voltage-level translation: inputs tolerate up to 5.5 V regardless of VCC (1.65–5.5 V), allowing interfacing between mixed-voltage domains. The Ioff feature disables outputs during power-down, blocking back-drive current and enabling live insertion in hot-swap systems.

FAQ

What logic functions can be implemented by the SN74LVC1G97YZAR?

The SN74LVC1G97YZAR supports nine fixed logic functions determined by the combination of its three inputs (In0–In2): 2-to-1 multiplexer, 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 hardwired per input pattern-no configuration register or programming is required. All functions operate across the full 1.65–5.5-V VCC range with Schmitt-trigger inputs.

Does the SN74LVC1G97YZAR support partial-power-down operation?

Yes, the SN74LVC1G97YZAR fully supports partial-power-down via its Ioff feature. When VCC = 0 V, the Ioff circuitry disables all outputs and limits input/output leakage to ±10 µA maximum, preventing damaging back-current flow from live system buses into the unpowered device. This enables safe hot-swap capability in modular power supplies and field-replaceable units-verified per JESD78 Class II latch-up standards.

What is the significance of Schmitt-trigger inputs in the SN74LVC1G97YZAR?

The Schmitt-trigger inputs of the SN74LVC1G97YZAR provide hysteresis (ΔVT = 0.53–1.04 V depending on VCC), giving distinct positive-going (VT+) and negative-going (VT–) input thresholds. This eliminates chatter and false triggering caused by slow-rising signals, contact bounce, or noise on long traces-making it ideal for interfacing with mechanical switches, analog comparators, or low-speed sensor outputs without external filtering components.

Can the SN74LVC1G97YZAR interface between 5-V and 3.3-V systems?

Yes, the SN74LVC1G97YZAR supports voltage translation: its inputs tolerate up to 5.5 V regardless of VCC level (1.65–5.5 V), and its outputs swing rail-to-rail relative to VCC. For example, with VCC = 3.3 V, it can accept 5-V input signals and produce clean 3.3-V logic outputs-enabling direct connection between legacy 5-V peripherals and modern 3.3-V MCUs without external level shifters.

What package type and dimensions does the SN74LVC1G97YZAR use?

The SN74LVC1G97YZAR uses a 6-ball DSBGA (Die Size Ball Grid Array) package designated YZP, with nominal dimensions of 1.41 mm × 0.91 mm and a 0.4-mm ball pitch. It is part of TI's NanoFree™ packaging technology, where the silicon die itself serves as the package-eliminating leadframe and mold compound to achieve the industry's smallest footprint for single-gate logic. This package is optimized for automated placement in high-density portable and wearable PCBs.
