BIDIRECTIONAL
TRANSCEIVER
DESCRIPTION:
The FCT162H245T 16-bit transceiver is built using advanced dual metal
CMOS technology. These high-speed, low-power transceivers are ideal for
synchronous communication between two busses (A and B). The Direction and
Output Enable controls operate these devices as either two independent 8-bit
transceivers or one 16-bit transceiver. The direction control pin (xDIR) controls
the direction of data flow. The output enable pin (xOE) overrides the direction
control and disables both ports. All inputs are designed with hysteresis for
improved noise margin.
The FCT162H245T has "Bus Hold" which retains the input's last state
whenever the input goes to high impedance. This prevents "floating" inputs and
eliminates the need for pull-up/down resistors.
