Product details

Active production, automotive-qualified octal latch

The Texas Instruments SN74HCS373QWRKSRQ1 is an octal D-type transparent latch with tri-state outputs, organized as 8:8 circuit. Propagation delay is 9.6ns, adequate for moderate-speed bus isolation and data storage applications. Output high/low current is 7.8mA each, sufficient for driving typical CMOS loads.

Package and mounting for automated assembly

Housed in a 20-VFQFN Exposed Pad package (2.5x4.5mm body), this part supports surface-mount assembly with wettable flanks for improved solder-joint inspection. The exposed pad aids thermal dissipation when soldered to a PCB ground plane. Supplied in Tape & Reel, it is ready for pick-and-place lines.

It is ROHS3 compliant.

Frequently asked questions

Is SN74HCS373QWRKSRQ1 suitable for 5V operation?

Yes, the supply range is 2V to 6V, so 5V operation is within spec. The 9.6ns propagation delay and 7.8mA output drive are characterized at 5V typical conditions.

What is the difference between SN74HCS373 and 74HC373?

The older 74HC373 typically comes in DIP/SOIC with commercial or industrial temperature grades. Both are octal transparent latches with tri-state outputs.
