Part Number: 74HC173
Function: Quad D-type flip-flop, positive-edge trigger, 3-state
Package: DIP, SOP 16 Pin Type
Manufacturer: Philips Electronics ( https://www.nxp.com/ )
The 74HC173 / 74HCT173 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
The devices are 4-bit parallel load registers with clock enable control, 3-state buffered outputs (Q0to Q3) and master reset (MR).
The master reset input (MR) is an active HIGH asynchronous input. When MR is HIGH, all four flip-flops are reset (cleared) independently of any other input condition.
The 3-state output buffers are controlled by a 2-input NOR gate.
1. Gated input enable for hold (do nothing) mode
2. Gated output enable control
3. Edge-triggered D-type register
4. Asynchronous master reset
5. Output capability: bus driver
6. ICC category: MSI
