U74AHC245

UNISONIC TECHNOLOGIES CO., LTD U74AHC245 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS CMOS IC  DESCRIPTION The U74AHC245 octal bus transceivers is designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable ( OE ) input can be used to disable the device so that the buses are effectively isolated. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  FEATURES * Operating range 2V to 5.5V VCC  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74AHC245L-D20-T U74AHC245G-D20-T U74AHC245L-S20-R U74AHC245G-S20-R U74AHC245L-R20-R U74AHC245G-R20-R U74AHC245L-P20-R U74AHC245G-P20-R Package DIP-20 SOP-20 SSOP-20 TSSOP-20 Packing Tube Tape Reel Tape Reel Tape Reel U74AHC245G-D20-T (1)Packing Type (2)Package Type (3)Green Package (1) T: Tube, R: Tape Reel (2) D20: DIP-20, S20: SOP-20, R20: SSOP-20 P20: TSSOP-20 (3) G: Halogen Free and Lead Free, L: Lead Free  MARKING DIP-20 SOP-20 / SSOP-20 / TSSOP-20 www.unisonic.com.tw Copyright © 2021 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-987.D U74AHC245  PIN CONFIGURATION CMOS IC ...
