IDT74FCT3245/A

3.3V CMOS OCTAL

BIDIRECTIONAL

TRANSCEIVER

DESCRIPTION:

The FCT3245/A octal transceivers are built using advanced dual metal

CMOS technology. These high-speed, low-power transceivers are ideal

for asynchronous communication between two buses (A and B). The

direction control pin (DIR) controls the direction of data flow. The output

enable pin (OE) overrides the direction control and disables both ports. All

inputs are designed with hysteresis for improved noise margin.

The FCT3245/A has series current limiting resistors. These offer low

ground bounce, minimal undershoot, and controlled output fall times-

reducing the need for external series terminating resistors.
