74AC299 - 8-Input Universal Shift/Storage Register

Description

The AC/ACT299 is an 8-bit universal shift/storage register with 3-STATE outputs.

Four modes of operation are possible: hold (store), shift left, shift right and load data.

The parallel load inputs and flip-flop outputs are multiplexed to reduce the total number of package pins.

Features

  • s ICC and IOZ reduced by 50% s Common parallel I/O for reduced pin count s Additional serial inputs and outputs for expansion s Four operating modes: shift left, shift right, load and store s 3-STATE outputs for bus-oriented.

Four modes of operation are possible: hold (store), shift left, shift right and load data. The parallel load inputs and flip-flop outputs are multiplexed to reduce the total number of package pins. Additional outputs are provided for flip-flops Q0, Q7 to allow easy serial cascading. A separate active LOW Master Reset is used to reset the register.
