Description
Pericom Semiconductor’s PI49FCT series of logic circuits are
produced using the Company’s advanced submicron CMOS
technology to achieve fast speed, low skew, fast slew rate, and low
propagation delay for most computing and communication
applications.
The PI49FCT32805 are non-inverting drivers. The outputs are
configured into 2 groups of 1-in, 5-out with independent output
enable. Group B has an extra MON output. Excellent output signals
to power and ground ratio minimize power and ground noise, and
also improves output performance.
PI49FCT32805 integrate series damping resistors on all outputs.

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V, +25°C ambient and maximum loading.
3. VOH = VCC – 0.6V at rated current.
4. This parameter is determined by device characterization but is not production tested.
5. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
