74HC/HCT40104 4-bit Bidirectional Universal Shift Register; 3-state

The 74HC/HCT40104 are high-speed Si-gate CMOS devices and are pin compatible with the '40104' of the '4000B' series. They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT40104 are universal Shift registers featuring parallel inputs, parallel outputs, shift-right and shift-left serial inputs and 3-state outputs allowing the devices to be used in bus-organized systems.In the parallel-load mode (S0 and S1 are HIGH), data is loaded into the associated Flip-Flop and appears at the output after the positive transition of the Clock input (CP).During loading, serial data flow is inhibited. Shift-right and shift-left are accomplished synchronously on the positive Clock edge with serial data entered at the shift-right (DSR) and shift-left (DSL) serial inputs, respectively. Clearing the Register is accomplished by setting both mode controls (S0 and S1) LOW and clocking the Register When the output enable input (OE) is LOW, all outputs assume the high-impedance OFF-state (Z).
