SN74BCT640DWRE4
八路总线收发器与3态输出 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS
description
The ′BCT640 bus transceiver is designed for asynchronous communication between data buses. These devices transmit data from the A bus to the B bus or from the B bus to the A bus depending upon the 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.
State-of-the-Art BiCMOS Design Substantially Reduces Standby Current
Outputs Have Undershoot-Protection Circuitry
Power-Up High-Impedance State
Buffered Control Inputs to Reduce DC Loading Effects
ESD Protection Exceeds 2000 V Per MIL-STD-883C, Method 3015
Package Options Include Plastic Small-Outline DW Packages, Ceramic Chip Carriers FK and Flatpacks W, and Plastic and Ceramic 300-mil DIPs J, N
