Description

These SN54ABT2245 octal transceivers and line drivers are designed for asynchronous communication between data buses. The SN54ABT2245 devices 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 (DIR) input. The output-enable (OE) input can be used to disable the device so the buses are effectively isolated. The B-port outputs, which are designed to sink up to 12 mA, include equivalent 25- series resistors to reduce overshoot and undershoot.

When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking/current-sourcing capability of the driver. The SN54ABT2245 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ABT2245 is characterized for operation from 40°C to 85°C.
