Product Description
Pericom Semiconductor’s PI74SSTV16857 series of logic circuits
are produced using the Company’s advanced 0.35 micron CMOS
technology, achieving industry leading speed.
The 14-bit PI74SSTV16857 universal bus driver is designed
for 2.3V to 2.7V V
the RESET input which is LVCMOS.
Data flow from D to Q is controlled by the differential clock , CLK,
CLK and RESET. Data is triggered on the positive edge of CLK.
CLK must be used to maintain noise margins.
RESET must be supported with LVCMOS levels as V
be stable during power-up. RESET is asynchronous and is intended
for power-up only and when low assures that all of the registers reset
to the Low State, Q outputs are low, and all input receivers, data and
clock, are switched off.
Pericom’s PI74SSTV16857 is characterized for operation from
0° to 70°C.
