Description
Pericom Semiconductor ’s PI49FCT3805 is a 3.3V non-inverting
clock driver and the PI49FCT3806 is a 3.3V inverting clock driver
designed with two independent groups of buffers. These buffers
have 3-state Output Enable inputs (active LOW) with a 1-in, 5-out
confi guration per group. Each clock driver consist of two banks of
drivers, driving fi ve outputs each from a standard TTL compatible
CMOS input.
Features
• 3.3V version of PI49FCT805/806
• Extremely low output skew: 0.5ns
• Monitor ouput pin
• Clock busing wih 3-state control
• TTL input and CMOS output compatible
• Industrial operation at –40°C to 85°C
• Extremely low static power (1mW, typ.)
• Hysteresis on all inputs
• Packaging (Pb-free & Green available):
– 20-pin 300-mil wide SOIC (S)
– 20-pin 150-mil wide QSOP (Q)
– 20-pin 209-mil wide SSOP (H)

Note:
Stresses greater than those listed under MAX I MUM RAT -
INGS may cause permanent damage to the device. This is
a stress rating only and functional operation of the device
at these or any other con di tions above those indicated in
the operational sec tions of this specifi cation is not implied.
Exposure to absolute maximum rating conditions for ex-
tended periods may affect reliability.
Maximum Ratings
(Above which the useful life may be impaired. For user guidelines, not tested.)
Notes:
1. For Max. or Min. conditions, use appropriate value specifi ed 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.
