U74HC164

UNISONIC TECHNOLOGIES CO., LTD U74HC164 8-BIT SERIAL-IN AND PARALLEL-OUT SHIFT REGISTER  DESCRIPTION The U74HC164 is an 8-bit edge-triggered shift registers with serial input and parallel output. A LOW-to-HIGH transition on the CP will shifts the data one place to the right which is the logical AND of DSA and DSB. A Low level on the MR will clear the registers asynchronously and force the outputs LOW.  FEATURES * Operation Voltage Range: 2~6V * Asynchronous Reset Input * Specified from -40~ +125°С  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HC164L-D14-T U74HC164G-D14-T U74HC164L-S14-R U74HC164G-S14-R U74HC164L-P14-R U74HC164G-P14-R Package DIP-14 SOP-14 TSSOP-14 CMOS IC DIP-14 SOP-14 TSSOP-14 Packing Tube Tape Reel Tape Reel  MARKING DIP-14 SOP-14 / TSSOP-14 www.unisonic.com.tw Copyright © 2018 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-309.D U74HC164  PIN CONFIGURATION DSA 1 DSB 2 Q0 3 Q1 4 Q2 5 Q3 6 GND 7  FUNCTION TABLE INPUT MR CP DSA LXX HLX H↑H H↑H H↑ L H↑ L  FUNCTIONAL DIAGRAM Logic Diagram 14 VCC 13 Q7 12 Q6 11 Q5 10 Q4 9 MR 8 CP CMOS IC DSB X X L H H L OUTPUT Q0 Q1 to Q7 L L to L Q0 Q1 to Q7 L Q0 to Q6 H Q0 to Q6 L Q0 to Q6 L Q0 to Q6 IEC Logic Symbol UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-309.D U74HC164 CMOS IC  ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5~ +7 V VCC or GND Current ICC ±50 mA Output Current IOUT ±25 mA Input Diode Curr...
