DESCRIPTION:
The FCT3245/A octal transceivers are built using ad-
vanced dual metal CMOS technology. These high-speed,
low-power transceivers are ideal for synchronous communi-
cation between two busses (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 have series current limiting resistors.
These offer low ground bounce, minimal undershoot, and
controlled output fall times-reducing the need for external
series terminating resistors.
