UNISONIC TECHNOLOGIES CO.
, LTD U74HC640 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS „ DESCRIPTION The U74AHC640 is a octal bus transceivers with 3-state outputs.
It is designed for asynchronous two-way communication between data buses.
Depending on the direction-control (DIR) input, data are transmitted from the A bus to the B bus or from the B bus to the A bus.
When OE is high, the buses are effectively isolated.
When OE is low, the buses are enable.
