HEF4021BT-Q100

8-bit static shift register

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 VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Connect unused inputs must to VDD, VSS, 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.
