HEF4021B-Q100
8-bit static shift register
Rev. 3 — 30 August 2013
Product data sheet
1. General description
The HEF4021B-Q100 is an 8-bit static shift register (parallel-to-serial converter). It has a
synchronous serial data input (DS), a clock input (CP) and an asynchronous active HIGH
parallel load input (PL). The HEF4021B-Q100 also has 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
register position. All the data in the register is shifted one position to the right on the
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
DD
power supply range of
3 V to 15 V referenced to V
SS
(usually ground). Connect unused inputs must to V
DD
, V
SS
,
or another input. This product has been qualified to the Automotive Electronics Council
(AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
