UNISONIC TECHNOLOGIES CO., LTD UCD4021B Preliminary CMOS IC 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 Lead Free Halogen Free UCD4021BL-S16-R UCD4021BG-S16-R UCD4021BL-S16-T UCD4021BG-S16-T UCD4021BL-P16-R UCD4021BG-P16-R UCD4021BL-P16-T UCD4021BG-P16-T www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd Package Packing SOP-16 SOP-16 TSSOP-16 TSSOP-16 Tape Reel Tube Tape Reel Tube 1 of 10 QW-R502-889.b UCD4021B Preliminary CMOS IC PIN CONFIGURATION UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 10 QW-R502-889.b UCD4021B Preliminary CMOS IC LOGIC DIAGRAM CL CL p P CL n P Q D p CL = CL D PS p p n n CL PS n CL CL p Q CL p n n CL CL TRUE TABLE CL SER IN X X X X X X X X PAR SER CONTROL 1 1 1 1 P1 Pn 0 0 1 1 0 1 0 1 Q1 (INTERNAL) 0 0 1 1 0 0 X X 0 Qn-1 1 0 X X 1 Qn-1 X 0 X X Q1 (NC) Qn (NC) Qn 0 1 0 1 NOTE: X = DON’T CARE CASE, NC = NO CHANGE UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 10 QW-R502-889.b UCD4021B Preliminary CMOS IC ABSOLUTE MAXIMUM RATING (unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5 ~ 20 V Input Voltage VIN -0.5 ~ VCC + 0.5 V Output Voltage VOUT -0.5 ~ VCC + 0.5 V Input Clamp Current (VIN<0, or VIN>VCC) IIK ±10 mA mW 500 TA=-40°C ~ +100°C PD Power Dissipation mW TA=+100°C ~ +125°C 200 Storage Temperature TSTG -65 ~ +150 °C Note: 1.
