U74HCT245

UNISONIC TECHNOLOGIES CO., LTD U74HCT245 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS  DESCRIPTION The U74HCT245 is designed for the asynchronous communication between data buses. While the direction-control(DIR) is high, data transmits from the A bus to the B bus. Data transmits from the B bus to the A bus if DIR is low. The output-enable OE will isolate the device from the buses when high voltage is applied on it.  FEATURES * Operate from 4.5V to 5.5V * Typical tPD is 14ns at 5.5V * Inputs are TTL Voltage Compatible  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HCT245L-D20-T U74HCT245G-D20-T U74HCT245L-S20-R U74HCT245G-S20-R U74HCT245L-R20-R U74HCT245G-R20-R U74HCT245L-P20-R U74HCT245G-P20-R Package DIP-20 SOP-20 SSOP-20 TSSOP-20 CMOS IC DIP-20 SOP-20 SSOP-20 TSSOP-20 Packing Tube Tape Reel Tape Reel Tape Reel  MARKING DIP-20 SOP-20 / SSOP-20 / TSSOP-20 www.unisonic.com.tw Copyright © 2022 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-646.E U74HCT245  PIN CONFIGURATION CMOS IC  FUNCTION TABLE INPUT OE DIR FUNCTION H X Isolation L H Transmit data from A bus to B bus L L Transmit data from B bus to A bus Note: H: HIGH voltage level; L: LOW voltage level.  LOGIC DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-646.E U74HCT245 CMOS IC  ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT Supply Voltage Input Clamp Current (ViN<0) Output Clamp Current (VOUT<0) Output Current VCC ...
