Description

The 16-bit transceivers are built using advanced dual metal CMOS technology. These high-speed, low-power transceiv- ers 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 trans- ceivers or one 16-bit transceiver. The direction control pin IDTCT (xDIR) controls the direction of data flow. The output enable pin (x) overrides the direction control and disables both ports. All inputs of IDTCT are designed with hysteresis for improved k noise margin.

The FCT16245T are ideally suited for driving high-capaci- tance loads and low-impedance backplanes. The output buff- ers are designed with power off disable capability to allow "live nsertion" of boards when used as backplane drivers.

The FCT162245T have 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 are plug-in replacements for the FCT16245T and ABT16245 for on-board interface applications.

The FCT166245T are suited for very low noise, point-to- point driving where there is a single receiver, or a light lumped
