U74HC373G-S20-R

UNISONIC TECHNOLOGIES CO., LTD U74HC373 CMOS IC OCTAL D-TYPE TRANSPARENT LATCH  DIP-20 DESCRIPTION The U74HC373 consists 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 output-enable (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. SOP-20 SSOP-20 TSSOP-20  FEATURES * Operation Voltage Range: 2~6V * Drive Up to 15 LSTTL Loads * 3-State Outputs * Output Capability Suitable for Bus Driving  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HC373L-D20-T U74HC373G-D20-T U74HC373L-S20-R U74HC373G-S20-R U74HC373L-R20-R U74HC373G-R20-R U74HC373L-P20-R U74HC373G-P20-R  Package Packing DIP-20 SOP-20 SSOP-20 TSSOP-20 Tube Tape Reel Tape Reel Tape Reel MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-296.D U74HC373  PIN CONFIGURATION  FUNCTION TABLE INPUTS(LE) INPUTS( OE ) L H L H L L H X Note: H: HIGH voltage level; L: LOW voltage level.  LOGIC SYMBOL  LOGIC DIAGRAM CMOS IC INPUTS(D) H L X X UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw OUTPUT(Q) H L Q0 Z 2 of 5 QW-R502-296.D U74HC373  CMOS IC ABSOLUTE MAXIMUM RATING (TA=25°С, unless otherwise specified) PARAMETER SYMBOL RATINGS UNIT Supply Voltage VCC -0.5 ~ 7 V VCC or GND Current ICC ±70 mA Output Current IOUT ±35 mA Input Clamp Current IIK ±20 mA Output Clamp Current IOK ±20 mA Operating Temperature TOPR -40 ~ + 85 °C Storage Temperature TSTG -65 ~ + 150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
