SN54AC245, SN74AC245 SCAS461I – FEBRUARY 1995 – REVISED APRIL 2024 SNx4AC245 Octal Bus Transceivers With 3-State Outputs 1 Features VCC operation of 2V to 6V Inputs accept voltages to 6V Max tpd of 7ns at 5V 2 Applications Pro Audio Video and Signage Appliances Factory Automation and Control 3 Description The 'AC245 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 be used to disable the device so that the buses are effectively isolated.
