Features, Applications

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)

Pericom Semiconductors PI49FCT series of logic circuits are produced using the Companys advanced 0.8 micron CMOS technology, achieving industry leading speed grades. The 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 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, +25C 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.
