UNISONIC TECHNOLOGIES CO., LTD U74HC164 CMOS IC 8-BIT SERIAL-IN AND PARALLEL-OUT SHIFT REGISTER DIP-14 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. SOP-14 A Low level on the MR will clear the registers asynchronously and force the outputs LOW. TSSOP-14 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 U74HC164G-S14-R U74HC164G-P14-R Package Packing DIP-14 SOP-14 TSSOP-14 Tube Tape Reel Tape Reel MARKING DIP-14 www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd SOP-14 / TSSOP-14 1 of 5 QW-R502-309.C U74HC164 CMOS IC PIN CONFIGURATION DSA 1 14 VCC DSB 2 13 Q7 Q0 3 12 Q6 Q1 4 11 Q5 Q2 5 10 Q4 Q3 6 9 MR GND 7 8 CP FUNCTION TABLE INPUT MR CP OUTPUT DSA DSB Q0 Q1 to Q7 L X X X L L to L H ↑ H L L Q0 to Q6 H ↑ H H H Q0 to Q6 H ↑ L H L Q0 to Q6 H ↑ L L L Q0 to Q6 FUNCTIONAL DIAGRAM Logic Diagram IEC Logic Symbol UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-309.C U74HC164 CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER Supply Voltage VCC or GND Current Output Current Input Diode Current Switch Diode Current RATINGS UNIT -0.5~ +7 V ±50 mA ±25 mA ±20 mA ±20 mA DIP-14 750 mW Power Dissipation PD SOP-14 500 mW TSSOP-14 500 mW Storage Temperature TSTG -65 ~ +150 °С Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
