This tranceiver is designed for asynchronous two-way munication between data buses. The direction control input pin (x DIR) determines the direction of the data flow through the bidirectional transceiver. The Direction and Output Enable controls are designed to operate this device as either two independent 8-bit tranceivers or one 16-bit transceiver. The output enable (x OE) input, when HIGH, disables both A and B ports by placing them in HIGH Z condition. The PI74LVTCH16245 has "Bus Hold" which retains the data input's last valid logic state whenever the data input goes to highimpedance, preventing "floating" inputs and eliminating the need for pull-up/down resistors. When VCC is between 0 to 1.5V during power up or power down, the outputs of the device are in the high-impedance state. To ensure the high-impedance state above 1.5V, 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....
