HD74BC620A - Octal Bus Transceivers With 3 State Outputs

Description

The HD74BC620A provides high drivability and operation equal to or better than high speed bipolar standard logic IC by using Bi-CMOS process.

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. This device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic levels at the enable inputs (GBA and GAB). The enable inputs can be used to disable the device so that the buses are effectively isolated. Features.
  • Inpu.
