Clock busing with Hi-Z state control
TTL input and output levels, reducing problematic
“ground bounce”
Extremely low static power (1mW, typical)
Hysteresis on all inputs
ESD protection exceeds 2000V
Industrial Operation: –40°C to 85°C
Package available:
– 16-pin 300-mil wide plastic SOIC (S)
The PI49FCT3804 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.

(Above which the useful life may be impaired. For user guidelines, not tested.)
Note:
Stresses greater than those listed under MAXIMUM RATINGS
may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any
other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
reliability.
