DSC-2650/5

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.
