MC74ACT299 Datasheet (Motorola) - 8-Input Universal Shift/Storage Register

MC74ACT299, 8-Input Universal Shift/Storage Register

The MC74AC299/74ACT299 contains eight edge-triggered D-type flip-flops and the interstage logic necessary to perform synchronous shift left, shift right, parallel load and hold operations.

The type of operation is determined by S0 and S1, as shown in the Truth Table.

All flip-flop outputs are brough

( DataSheet : www.DataSheet4U.com ) MC74AC299 MC74ACT299 8ĆInput Universal Shift/Storage Register with Common Parallel I/0 Pins 8-INPUT UNIVERSAL SHIFT/STORAGE REGISTER WITH COMMON PARALLEL I/O PINS The MC74AC299/74ACT299 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.
