74HC299 Datasheet (nexperia) - 8-bit universal shift register

74HC299, 8-bit universal shift register

The 74HC299 is an 8-bit universal shift register with 3-state outputs.

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

The type of operation is determined by the mode select input
