DESCRIPTION:
The 16-bit transceivers are 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 are 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.
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...
