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 HD74BC640A features low power dissipation that is about 1/5 of high speed bipolar logic IC. When the frequency is 10 MHz. The HD74BC640A 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, disables both A and B ports by placing then in a high impedance.
