Description

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 (active-HIGH) 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 25ohm-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. These transceivers are designed for low voltage (3.3V) VCCapplications, but with the capability to provide a TTL interface to a 5V environment. The LVT2245 and LVTH2245 are fabricated with an advanced BiCMOS technology to achieve high speed operation similar to 5V ABT while maintaining low power dissipation.
