HCF4021B ASYNCHRONOUS PARALLEL IN OR SYNCHRONOUS SERIAL IN/SERIAL OUT 8 - STAGE STATIC SHIFT REGISTER s MEDIUM SPEED OPERATION : 12 MHz (Typ.) CLOCK RATE AT VDD - VSS = 10V s FULLY STATIC OPERATION s 8 MASTER-SLAVE FLIP-FLOPS PLUS OUTPUT BUFFERING AND CONTROL GATING s QUIESCENT CURRENT SPECIFIED UP TO DIP SOP 20V s 5V, 10V AND 15V PARAMETRIC RATINGS s INPUT LEAKAGE CURRENT ORDER CODES II = 100nA (MAX) AT VDD = 18V TA = 25°C PACKAGE TUBE T & R s 100% TESTED FOR QUIESCENT CURRENT DIP HCF4021BEY s MEETS ALL REQUIREMENTS OF JEDEC JESD13B " STANDARD SPECIFICATIONS SOP HCF4021BM1 HCF4021M013TR FOR DESCRIPTION OF B SERIES CMOS DEVICES" In this device, entry is controlled by the DESCRIPTION PARALLEL/SERIAL CONTROL input. When the The HCF4021B is a monolithic integrated circuit PARALLEL/SERIAL CONTROL input is low, data fabricated in Metal Oxide Semiconductor is serially shifted into the 8-stage register technology available in DIP and SOP packages. synchronously with the positive transition of he This device is an 8-stage parallel or serial input/ clock line. When the PARALLEL/SERIAL serial output register having common CLOCK and CONTROL input is high, data is jammed into the PARALLEL/SERIAL CONTROL inputs, a single 8-stage register via the parallel input lines and SERIAL data input, and individual parallel "JAM" synchronous with the positive transition of the inputs to each register stage. Each register stage clock line, the CLOCK input of the internal stage is is a D-type, master-slave flip-flop in addition to an
