HEF4021B

8-bit static shift register

Rev. 9 — 30 August 2013

Product data sheet

1. General description

The HEF4021B is an 8-bit static shift register (parallel-to-serial converter) with a

synchronous serial data input (DS), a clock input (CP), an asynchronous active HIGH

parallel load input (PL), eight asynchronous parallel data inputs (D0 to D7) and buffered

parallel outputs from the last three stages (Q5 to Q7).

Each register stage is a D-type master-slave flip-flop with a set direct (SD) and clear direct

(CD) input. Information on D0 to D7 is asynchronously loaded into the register while PL is

HIGH, independent of CP and DS. When PL is LOW, data on DS is shifted into the first

LOW-to-HIGH transition of CP. Schmitt trigger action makes the clock input highly tolerant

of slower rise and fall times.

It operates over a recommended V_DDpower supply range of 3 V to 15 V referenced to V_SS

(usually ground). Unused inputs must be connected to V_DD, V_SS, or another input.

2. Features and benefits

 Tolerant of slower rise and fall times

 Fully static operation

 5 V, 10 V, and 15 V parametric ratings

 Standardized symmetrical output characteristics

 Specified from 40 C to +125 C

 Complies with JEDEC standard JESD 13-B

3. Ordering information
