Overview
HD74BC640A
Octal Bus Transceivers With 3 State Outputs
ADE-205-026 (Z) Rev.
0 June 1993 Description
The HD74BC640A provides high drivability and operation equal to or better than high speed bipolar standard logic IC by using Bi-CMOS process.
The device features low power dissipation that is about 1/5 of high speed bipolar logic IC.
When the frequency is 10 MHz.
The device has eight bus transceivers with three state outputs in a 20 pin package.
Each device has an active low enable input ( G ) and a direction control input, DiR.
When DiR is high, data flows from the A inputs to the B outputs.
When DiR is high, data flows from the B inputs to the A outputs.
When enable inputs (G) is high, disab...
