HD74HC91 Datasheet (Renesas) - 8-bit Shift Register

HD74HC91, 8-bit Shift Register

This serial-in, serial-out, 8-bit shift register is composed of eight R-S master-slave flip-flops, input gating, and a clock drive.

Single-rail data and input control are gated through inputs A and B and an internal inverter to form the complementary inputs to the first bit of the shift register.
