Product Features
ProductDescription
PI74ALVTC16827isdesignedforlowvoltageoperation,
Pericom Semiconductors PI74ALVTC series of logic circuits are
produced using the Companys advanced 0.35 micron CMOS
technology, achieving industry leading speed.

The PI74ALVTC16827, is a 20-Bit non-inverting buffer/driver
designed for 1.65V to 3.6V Vcc operation.
HighDrive,32/64mA@3.3V
Uses patented noise reduction circuitry
Power-off high impedance inputs and outputs
Industrial operation at 40°C to +85°C
Packagesavailable:
A buffer/driver is composed of two 10-bit sections with separate
output-enable signals. For either 10-Bit buffer section, the two
output-enable (1OE1and1OE2or2OE1and2OE2inputsmustboth
belowforthecorrespondingYoutputstobeactive.Ifeitheroutput-
enable input is HIGH, the output of that 10-Bit buffer section are in
the high-impedance state.
56-pin240-milwideplasticTSSOP(A56)
56-pin173-milwideplasticTVSOP(K56)
To ensure the high-impedance state during power up or power
down, OE should be tied to Vcc through a pullup resistor whose
minimum value is determined by the current sinking capability of
the driver.
The family offers both I/O Tolerant, which allows it to operate in
mixed 1.65/3.6V systems, and Bus Hold, which retains the data
inputs last state preventing floating inputs and eliminating the
need for pullup/down resistors.
