General Description

The LCXH2245 contains eight non-inverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is designed for low voltage (2.5V and 3.3V) VCC applications. The T/R input determines the direction of data flow through the device. The OE input disables both the A and B ports by placing them in a high impedance state. The 26Ω series resistor in the B Port output helps reduce output overshoot and undershoot.
