MC74AC194 Datasheet (Motorola) - 4-Bit Bidirectional Universal Shift Register

MC74AC194, 4-Bit Bidirectional Universal Shift Register

The MC74AC/74ACT194 contains four edge-triggered D flip-flops and the necessary interstage logic to synchronously perform shift right, shift left, parallel load and hold operations.

Signals applied to the Select (S0, S1) inputs determine the type of operation, as shown in the Mode Select Table.
