This document describes the features of Harris Semiconductor SCHS158E, including three-state buffered outputs, gated input and output enables, wide operating temperature range, balanced propagation delay and transition times, significant power reduction compared to LSTTL logic ICs, etc.
Datasheet
CD54HC173 and CD54HCT173 are high speed three-state quad D-type flip-flops fabricated with silicon gate CMOS technol- ogy. They possess the low power consumption of standard CMOS Integrated circuits, and can operate at speeds com- parable to the equivalent low power Schottky devices. The buffered outputs can drive 15 LSTTL loads. The large output drive capability and three-state feature make these parts ide- ally suited for interfacing with bus lines in bus oriented sys- tems.
