54ACT299 - 8-Input Universal Shift/Storage Register

Download the 54ACT299 datasheet PDF. This datasheet also covers the 54AC299 variant, as both devices belong to the same 8-input universal shift/storage register family and are provided as variant models within a single manufacturer datasheet.

General Description

The ’AC/’ACT299 is an 8-bit universal shift/storage register with TRI-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.

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.
