  • PNP Inputs Reduce dc Loading on Bus Lines
  • Hysteresis at Bus Inputs Improves Noise Margins
  • Typical Propagation Delay Times Port to Port, 8 ns

Description

These octal bus transceivers are designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.

The devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE)\ input can disable the device so that the buses are effectively isolated.
