74HC165PW Datasheet

Logic - Shift Registers


The 74HCT165/ 74HC165PW are high-speed Si-gate CMOS devicesand are pin compatible with low power Schottky TTL(LSTTL). They are specified in compliance with JEDECstandard no. 7A.The 74HC/HCT165 are 8-bit parallel-load or serial-in shiftregisters with complementary serial outputs (Q7 andQ7) available from the last stage. When the parallel load(PL) input is LOW, parallel data from the D0 toD7 inputs are loaded into the register asynchronously.When PL is HIGH, data enters the register serially at theDs input and shifts one place to the right(Q0 → Q1 → Q2, etc.) with each positive-going clocktransition. This feature allows parallel-to-serial converterexpansion by tying the Q7 output to the DS input of thesucceeding stage.The clock input is a gated-OR structure which allows oneinput to be used as an active LOW clock enable (CE) input.The pin assignment for the CP and CE inputs is arbitraryand can be reversed for layout convenience. TheLOW-to-HIGH transition of input CE should only takeplace while CP HIGH for predictable operation. Either theCP or the CE should be HIGH before theLOW-to-HIGH transition of PL to prevent shifting the datawhen PL is activated. 74HC165PW Features • Asynchronous 8-bit parallel load• Synchronous serial input• Output capability: standard• ICC category: MSI 74HC165PW Applications • Parallel-to-serial data conversion
