BIDIRECTIONAL
TRANSCEIVER
DESCRIPTION:
The FCT16245T 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 FCT16245T is ideally suited for driving high-capacitance loads and low-
impedance backplanes. The output buffers are designed with power off disable
capability to allow "live insertion" of boards when used as backplane drivers.
