DESCRIPTION:
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.
ground bounce, minimal undershoot, and controlled output fall times-
reducing the need for external series terminating resistors.
The FCT3245/A octal transceivers are built using advanced dual metal
The FCT3245/A has series current limiting resistors. These offer low
