UNISONIC TECHNOLOGIES CO., LTD U74AHC164 CMOS IC 8-Bit Serial-In/Parallel-Out Shift Register DESCRIPTION The U74AHC164 is an 8-bit serial-in/parallel-out shift register. The logical AND of the Dsa and Dsb enters into Q0 and shifts one place to right on each LOW-to-HIGH transition of the clock (CP). A low level on the master reser ( MR )input clears all the register asynchronously and force all output LOW. FEATURES * Operate From 2V to 5.5V * Schmitt on all inputs * Balanced propagation delays ORDERING INFORMATION Ordering Number U74AHC164G-S14-R U74AHC164G-P14-R Package SOP-14 TSSOP-14 Packing Tape Reel Tape Reel MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-240.C U74AHC164 CMOS IC PIN CONFIGURATION FUNCTIONAL DIAGRAM 8 CP 9 1 2 MR Dsa Dsb Q0 3 Q1 4 Q2 5 Q3 6 Q4 10 Q5 11 Q6 12 Q7 13 FUNCTION TABLE INPUTS(CP) INPUTS(Dsa) INPUTS(Dsb) OUTPUTS(Q0) INPUTS( MR ) L X X X L H ↑ L L L H ↑ L H L H ↑ H L L H ↑ H H H Note: H: HIGH voltage level; L: LOW voltage level; ↑: LOW-to-HIGH transition; ×: don’t care.
