Series Resistors, So No External Resistors Are RequiredEPIC-IIB is a trademark of Texas Instruments Incorporated.
These octal transceivers and line drivers are designed for asynchronous communication between data buses. The 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.
Both the A-port and 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 capability of the driver.
The SN54ABTR2245 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABTR2245 is characterized for operation from -40°C to 85°C.
