8-bit Shift Register

Description

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. Drive for the internal

common clock line is provided by an inverting clock driver. This clock pulse inverter/driver causes these

circuits to shift information one bit on the positive edge of an input clock pulse.
