U74HC273

UNISONIC TECHNOLOGIES CO., LTD U74HC273 OCTAL D-TYPE FLIP-FLOPS WITH CLEAR  DESCRIPTION The U74HC273 devices are positive-edge-triggered D-type flip-flops with a direct active low clear (CLR) input. Information at the data (D) inputs meeting the setup time requirements is transferred to the Q outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not related directly to the transition time of the positive-going pulse. When CLK is at either the high or low level, the D input has no effect at the output.  FEATURES * Wide Operating Voltage Range of 2V to 6V * Low Power Consumption, 80-μA Maximum ICC *Typical tPD = 12ns * ±4mA Output Drive at 5V * Low Input Current of 1μA Maximum * Contain Eight Flip-Flops With Single-Rail Outputs * Direct Clear Input * Individual Data Input to Each Flip-Flop  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HC273L-D20-T U74HC273G-D20-T U74HC273L-S20-R U74HC273G-S20-R U74HC273L-R20-R U74HC273G-R20-R U74HC273L-P20-R U74HC273G-P20-R Package DIP-20 SOP-20 SSOP-20 TSSOP-20 CMOS IC Packing Tube Tape Reel Tape Reel Tape Reel  MARKING DIP-20 SOP-20 / SSOP-20 / TSSOP-20 www.unisonic.com.tw Copyright © 2023 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-B61.F U74HC273  PIN CONFIGURATION CLR 1 Q1 2 D1 3 D2 4 Q2 5 Q3 6 D3 7 D4 8 Q4 9 GND 10  FUNCTION TABLE INPUTS CLR CLK D L X X H ↑ H H ↑ L H L X H = High voltage level；L = Low volta...
