The LVT2245 and LVTH2245 contain eight non-inverting bidirectional buffers with 3-STATE outputs and are intended for bus-oriented applications. The Transmit/ Receive (T/R) input determines the direction of data flow through the bidirectional transceiver. Transmit (activeHIGH) enables data from A Ports to B Ports; Receive (active-LOW) enables data from B Ports to A Ports. The Output Enable input, when HIGH, disables both A and B Ports by placing them in a high impedance state. The equivalent 25 -series resistor in the B Port helps reduce output overshoot and undershoot. The LVTH2245 data inputs include bushold, eliminating the need for external pull-up resistors to hold unused inputs.
