This datasheet provides details about the characteristics and specifications of the SN54AHCT245 and SN74AHCT245 octal bus transceivers. Both devices are asynchronous, bidirectional data bus transceivers that can transmit data 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 input.
The document describes the SN54AHCT245 and SN74AHCT245 octal bus transceivers, designed for asynchronous two-way communication between data buses. These devices allow data transmission from the A bus to the B bus or vice versa, depending on the logic level at the direction-control (DIR) input. An output-enable (OE) input can be used to disable the device to isolate the buses.
| Supply Voltage Range | 4.5 V to 5.5 V |
|---|---|
| High-Level Output Current | -8 mA |
| Low-Level Output Current | 8 mA |
| Power Dissipation Capacitance | 13 pF |
The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.
Data transmission direction depends on the logic level at the direction-control (DIR) input.
