PI29FCT52T
PI29FCT53T
Fast CMOS
Registered Transceivers
Product Description:
Pericom Semiconductor's PI29FCT series of logic circuits are pro-
duced in the Company's advanced 0.8 micron CMOS technology,
achieving industry leading speed grades.
The PI29FCT52T and the PI29FCT53T are 8-bit registered
transceivers designed with two 8-bit back-to-back registers to store
data flowing in both directions between two bidirectional buses.
Separate clock enable and 3-state output enable signals are provided
for each register. The PI29FCT52T is a non-inverting option of the
PI29FCT53T.
Product Features:
PI29FCT52/53T is pin compatible with bipolar FASTTM
Series at a higher speed and lower power consumption
TTL input and output levels
Extremely low static power
Hysteresis on all inputs
Industrial operating temperature range: 40C to +85C
Packages available:
24-pin 300 mil wide plastic DIP (P)
24-pin 150 mil wide plastic QSOP (Q)
24-pin 150 mil wide plastic TQSOP (R)
24-pin 300 mil wide plastic SOIC (S)

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.
