Texas Instruments SN74AUC1G80YZAR

Overview

SN74AUC1G80YZAR from Texas Instruments is a single positive-edge-triggered D-type flip-flop in a 5-pin NanoFree™ (DSBGA) package, optimized for 1.65–1.95 V operation with 1.9 ns max propagation delay at 1.8 V, ±8 mA output drive, and Ioff support for partial-power-down mode - used in high-speed level-shifting and clock-domain synchronization in portable low-voltage logic systems.

For engineers reviewing the SN74AUC1G80YZAR datasheet, SN74AUC1G80YZAR pinout, SN74AUC1G80YZAR application, or SN74AUC1G80YZAR equivalent, key selection criteria include sub-2 ns timing at 1.8 V, 0.8–2.7 V operational range, Ioff-enabled power sequencing, latch-up immunity (>100 mA), and Pb-free WCSP packaging for ultra-compact PCB layouts.

Technical Context

This device implements a synchronous edge-triggered storage element with setup/hold times as low as 0.5 ns (at 2.5 V) and supports mixed-mode signal interfacing across voltage domains due to 3.6-V tolerant I/Os. Its internal circuitry enables reliable operation down to 0.8 V while maintaining specified timing margins.

The NanoFree™ package uses the silicon die as the package substrate, eliminating wirebonds and leadframe - resulting in minimal parasitic inductance and capacitance, critical for preserving signal integrity in high-frequency data paths up to 275 MHz maximum clock frequency.

FAQ

What is the minimum operating voltage for SN74AUC1G80YZAR?

The SN74AUC1G80YZAR is fully functional down to 0.8 V VCC, with guaranteed timing and electrical specifications across the full 0.8–2.7 V range. At 0.8 V, it achieves 5 ns max tpd and supports 50 MHz clock operation - enabling use in ultra-low-power modes where other logic families fail.

Does SN74AUC1G80YZAR support partial-power-down mode?

Yes, SN74AUC1G80YZAR features Ioff circuitry that disables outputs when VCC = 0 V, preventing damaging current backflow during partial power-down. This allows safe interconnection between powered and unpowered subsystems - a key requirement in modern multi-rail architectures.

What is the maximum clock frequency supported by SN74AUC1G80YZAR?

SN74AUC1G80YZAR supports up to 275 MHz maximum clock frequency at 2.5 V VCC with CL = 15 pF. At its target 1.8 V operating point, it achieves 250 MHz fmax - verified across –40°C to 85°C ambient temperature with full process/voltage/temperature corner coverage.

Is SN74AUC1G80YZAR pin-compatible with other 5-pin DFFs in TI's portfolio?

SN74AUC1G80YZAR shares identical pinout (D-GND-CLK-Q-VCC) with SN74AUC1G74YZPR and SN74AUC1G86YZPR in the YZP package, but differs functionally - SN74AUC1G80YZAR is a single DFF, while SN74AUC1G74YZPR is a dual DFF and SN74AUC1G86YZPR is an XOR gate. Electrical and thermal behavior remain consistent across YZP variants.

What package type does SN74AUC1G80YZAR use, and what are its key mechanical advantages?

SN74AUC1G80YZAR uses Texas Instruments' NanoFree™ WCSP (YZP) package - a 5-bump, Pb-free, bottom-terminated die-scale ball grid array. Its 0.87 mm² footprint and 0.37 mm max height reduce PCB area by ~65% versus SOT-23, while eliminating bond wires lowers inductance for superior high-frequency signal integrity.
