Product Description
Pericom Semiconductor鈥檚 PI74AVC
+
series of logic circuits are
produced using the Company鈥檚 advanced submicron CMOS
technology, achieving industry leading speed.
The PI74AVC
+
16827, is a 20-bit non-inverting buffer/driver
designed for 1.65V to 3.6V V
CC
operation.
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 (1OE1 and 1OE2 or 2OE1 and 2OE2 inputs must both
be low for the corresponding Y outputs to be active. If either output-
enable input is HIGH, the output of that 10-bit buffer section are in
the high-impedance state.
To ensure the high-impedance state during power up or power down,
OE should be tied to V
CC
through a pullup resistor whose minimum
value is determined by the current sinking capability of the driver.
