PI74FCT399T
Fast CMOS Quad Dual-Port Register
Product Description:
ProductFeatures:
• PI74FCT399TispincompatiblewithbipolarFAST™Seriesat
a higher speed and lower power consumption
• TTL input and output levels
Pericom Semiconductor’s PI74FCT series of logic circuits are pro-
duced in the Company’s advanced 0.8 micron CMOS technology,
achieving industry leading speed grades.
These high-speed quad dual-port registers select 4-bit wide data
from one of the two sources (Ports) under control of a common
Select input (S). Synchronous with the LOW-to-HIGH transition
of the Clock input (CP), the selected data is transferred to a 4-bit
output register. The 4-bit D-type output register is fully edge-
triggered. Forpredictableoperation, theDatainputs(IAX, IBX)and
Select input (S) must be stable one set-up time prior to, and hold
time after, the LOW-to-HIGH transition of the Clock input.
• Extremelylowstaticpower
• Hysteresis on all inputs
• Industrial operating temperature range: –40°C to +85°C
• Packagesavailable:

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.

3. Per TTL driven input (VIN = 3.4V); all other inputs at Vcc or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
5. Values for these conditions are examples of the Icc formula. These limits are guaranteed but not tested.
6. IC =IQUIESCENT + IINPUTS + IDYNAMIC
