Fast CMOS
Buffer/Clock Driver
Product Features
• Low output skew: 0.8ns
• Clock busing with Hi-Z state control
• TTL input and output levels, reducing problematic
“ground bounce”
• High output drive, IOL = 64mA
• Extremely low static power (1mW, typ.)
• Hysteresis on all inputs
• Packages available:
– 16-pin 300 mil wide plastic SOIC (S)
– 16-pin 150 mil wide QSOP (Q)
Product Description
Pericom Semiconductor’s PI49FCT series of logic circuits are
produced using the Company’s advanced 0.8 micron CMOS
technology, achieving industry leading speed grades.
The PI49FCT804T is a non-inverting clock driver designed with two
independent groups of buffers. These buffers have Hi-Z state
Output Enable inputs (active LOW) with a 1-in, 4-out configuration
per group. Each clock driver consists of two banks of drivers,
driving four outputs each from a standard TTL compatible CMOS
input.

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 = 5.0V, +25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. This parameter is determined by device characterization but is not production tested.
