HEF4035B 4-bit Universal Shift Register

HEF4035B 4-bit universal Shift register The HEF4035B is a fully synchronous edge-triggered 4-bit Shift register with a Clock input (CP), four synchronous parallel data inputs (P0 to P3 ), two synchronous serial data inputs (J, K), a synchronous parallel enable input (PE), buffered parallel outputs from all 4-bit positions (O0 to O3 ), a true/complement input (T/C) and an overriding asynchronous master reset input (MR). Each Register is of a D-type master-slave Flip-Flop Operation is synchronous (except for MR) and is edge-triggered on the LOW to HIGH transition of the CP input. When PE is HIGH, data is loaded into the Register from P0 to P3 on the LOW to HIGH transition of CP. When PE is LOW, data is shifted into the first Register position from J and K and all the data in the Register is shifted one position to the right on the LOW to HIGH transition of CP. D-type entry is obtained by interconnecting J and K. When J = HIGH and K = LOW the first stage is in the toggle mode. When J = LOW and K = HIGH the first stage is in the hold mode.The outputs (O0 to O3 ) are either inverting or non-inverting, depending on T/C state. With T/C HIGH, O0 to O3 are non-inverting (active HIGH) and when T/C is LOW, O0 to O3 are inverting (active LOW).A HIGH on MR resets all four bit positions (O0 to O3 = LOW if T/C = HIGH, O0 to O3 = HIGH if T/C = LOW) independent of all other input conditions. Schmitt-trigger action in the Clock input makes the circuit highly tolerant to slower Clock rise and fall times.
