Product Summary
The HEF4021BT is an 8-bit static shift register(parallel-to-serial converter) with a synchronous serialdata input (DS), a clock input (CP), an asynchronous activeHIGH parallel load input (PL), eight asynchronous paralleldata inputs (P0 to P7) and buffered parallel outputs fromthe last three stages. The applications of the HEF4021BT include Industrial and automotive.
Parametrics
HEF4021BT absolute maximum ratings: (1)supply voltage: -0.5V to +18V; (2)input clamping current (VI < 0.5 V or VI >VDD+0.5 V): ±10mA; (3)input voltage: -0.5V to VDD+ 0.5V; (4)output clamping current(VO < 0.5V or VO>VDD+0.5V): ±10mA; (5)input/output current: ±10mA; (6)supply current: 50mA; (7)storage temperature: -65℃ to+150℃; (8)ambient temperature: -40℃ to+125℃; (9)total power dissipation (Tamb: 70 ℃ to +125℃): 8-500mW/K; (10)power dissipation: 100mW per output.
