Product Description
Pericom Semiconductor聮s PI74ALVCH series of logic circuits are
produced using the Company聮s advanced 0.5 micron CMOS
technology, achieving industry leading speed.
This 18-bit buffer and line driver is designed for 2.3V to 3.6V V
CC
operation.
PI74ALVCH16825 improves the performance and density of 3-
state memory address drivers, clock drivers, and bus-oriented
receivers and transmitters.
Providing true data, the device can be used as two 9-bit buffers or
one 18-bit buffer.
The 3-state control gate is a 2-input AND gate with Active-Low
inputs so that if either Output Enable (OE1 or OE2) input is HIGH,
all nine affected outputs are in the high-impedance state.
To ensure the high-impedance state during power up or power
down, OE should be tied to Vcc through a pull-up resistor; the
minimum value of the resistor is determined by the current-sinking
capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating
inputs at a valid logic level.
