HCF4021B Datasheet (STMicroelectronics) - 8-STAGE STATIC SHIFT REGISTERS

HCF4021B, 8-STAGE STATIC SHIFT REGISTERS

OF ”B” SERIES CMOS DEVICES” EY (Plastic Package) F (Ceramic Package) M1 (Micro Package) C1 (Plastic Chip Carrier) DESCRIPTION The HCC4014B, HCC4021B (extended temperature range) and the HCF4014B, HCF4021B (intermediate temperature range) are monolithic integrated circuits, available in 16-lead

HCC/HCF4014B HCC/HCF4021B 8-STAGE STATIC SHIFT REGISTERS 4014B 4021B SYNCHRONOUS PARALLEL OR SERIAL INPUT/SERIAL OUTPUT lines and synchronous with the positive transition of the clock line.

In the HCC/HCF4021B, the CLOCK input of the internal stage is ”forced” whenasynchronous parallel entry is made.

ASYNCHRONOUS PARALLEL INPUT OR SYNCHRONOUS SERIAL INPUT/SERIAL OUTPUT MEDIUM-SPEED OPERATION-12MHz (typ.) CLOCK RATE AT VDD
