1 / 10 page UNISONIC TECHNOLOGIES CO., LTD UCD4021B Preliminary CMOS IC www.unisonic.com.tw 1 of 10 Copyright © 2013 Unisonic Technologies Co., Ltd QW-R502-889.b CMOS 8-STAGE STATIC SHIFT REGISTERS DESCRIPTION The UCD4021B is a 8-stage synchronous parallel or serial input/serial output registers having common CLOCK and PARALLEL/SERIAL CONTROL inputs, a SERIAL data input, and individual parallel inputs to each register stage. Each register is a D-type, master-slave flip-flop. Q6, Q7, and Q8 are outputs. In UCD4021B serial entry is synchronous with the clock but parallel entry is asynchronous. In UCD4021B serial entry is controlled by the PARALLEL/SERIAL CONTROL input. When the PARALLEL/SERIAL CONTROL input is low, data is serially shifted into the 8-stage register synchronously with the positive transition of the clock line. When the PARALLEL/SERIAL CONTROL input is high, asynchronous parallel entry is made and the CLOCK input of the internal stage is isolated. FEATURES * Up to 20V operation voltage * 12MHz (Typ.) clock rate at 10V * Maximum input current of 1μA at 18V * Fully static operation * 8 master-slave flip-flops plus output buffering and control gating APPLICATIONS * General-purpose register * Parallel input/serial output data queueing * Parallel to serial data conversion ORDERING INFORMATION Ordering Number Package Packing Lead Free Halogen Free UCD4021BL-S16-R UCD4021BG-S16-R SOP-16 Tape Reel UCD4021BL-S16-T UCD4021BG-S16-T SOP-16 Tube UCD4021BL-P16-R UCD4021BG-P16-R TSSOP-16 Tape Reel UCD4021BL-P16-T UCD4021BG-P16-T TSSOP-16 Tube |
