IDT74FCT16245ETE description
The 16-bit transceivers are built using advanced dual
metal=B8=EA=B6=FBCMOS
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 ****ts. 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=A8C 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-topoint driving
where there is a single receiver, or a light lumped
