UNISONIC TECHNOLOGIES CO., LTD U74HC373 U74HC373 CMOS IC OCTAL D-TYPE TRANSPARENT LATCH DESCRIPTION The U74HC373 U74HC373 consist of eight D-type transparent latches with 3-state outputs. When letch enable (LE) is high, the latches operate at the transparent mode, and the latches' output will change corresponding with the data present at D0 to D7. When OE is low, the contents of the latches will be present at the outputs. The outputs will be in the high impedance when OE goes high. FEATURES * Operation voltage range: 2~6V * Drive up to 15 LSTTL loads * 3-state outputs * Output capability suitable for bus driving Lead-free: U74HC373L U74HC373L Halogen-free: U74HC373G U74HC373G ORDERING INFORMATION Normal U74HC373-P20-R U74HC373-P20-R Ordering Number Lead Free U74HC373L-P20-R U74HC373L-P20-R www.unisonic.com.tw Copyright © 2009 Unisonic Technologies Co., Ltd Halogen Free U74HC373G-P20-R U74HC373G-P20-R Package Packing TSSOP-20 TSSOP-20 Tape Reel 1 of 6 QW-R502-296 QW-R502-296.A U74HC373 U74HC373 CMOS IC PIN CONFIGURATION UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 6 QW-R502-296 QW-R502-296.A U74HC373 U74HC373 CMOS IC FUNCTION TABLE INPUTS( OE ) INPUTS(LE) L H L H L L H X Note: H: HIGH voltage level; L: LOW voltage level.
