Octal Serial/Parallel Register with Sign Extend

parallel load. An asynchronous Master Reset (MR) input

overrides clocked operation and clears the register.

General Description

The 74F322 is an 8-bit shift register with provision for either

serial or parallel loading and with 3-STATE parallel outputs

plus a bi-state serial output. Parallel data inputs and paral-

lel outputs are multiplexed to minimize pin count. State

changes are initiated by the rising edge of the clock. Four

synchronous modes of operation are possible: hold (store),

shift right with serial entry, shift right with sign extend and

Features

■ Multiplexed parallel I/O ports

■ Separate serial input and output

■ Sign extend function

■ 3-STATE outputs for bus applications
