U74HC245

UNISONIC TECHNOLOGIES CO., LTD U74HC245 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS  DESCRIPTION The U74HC245 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 2V to 6V * Max tPD is 18ns at 6V  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HC245L-D20-T U74HC245G-D20-T U74HC245L-S20-R U74HC245G-S20-R U74HC245L-R20-R U74HC245G-R20-R U74HC245L-P20-R U74HC245G-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-R502-639.F U74HC245  PIN CONFIGURATION DIR 1 A1 2 A2 3 A3 4 A4 5 A5 6 A6 7 A7 8 A8 9 GND 10 20 VCC 19 OE 18 B1 17 B2 16 B3 15 B4 14 B5 13 B6 12 B7 11 B8  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 CMOS IC UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-639.F U74HC245 CMOS IC  ABSOLUTE MAXIMUM RATING (TA=25°С, unless otherwise specified) PARAMETER SYMBOL RATINGS U...
