FAST CMOS 16-BIT
BIDIRECTIONAL
TRANSCEIVER
DESCRIPTION:
The FCT162245T 16-bit transceiver is built using advanced dual metal
CMOS technology. These high-speed, low-power transceivers are ideal for
synchronous communication between two buses (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 FCT162245T has balanced output drive with current limiting resistors.
This offers low ground bounce, minimal undershoot, and controlled output fall
times–reducing the need for external series terminating resistors. The
FCT162245T is a plug-in replacement for the FCT16245T and ABT16245 for
on-board interface applications.
