Pericom Semiconductor’s PI74ALVTC series of logic circuits are
produced using the Company’s advanced 0.35 micron CMOS
technology, achieving industry leading speed.
The PI74ALVTC16344 is a 1-bit to 4-bit buffer/driver designed
for 1.65V to 3.6V VCC operation.
The address/driver is designed for applications where four separate
memory locations must be addressed by a single address.
To ensure the high-impedance state during power up or power
down, OE should be tied to VCC through a pullup resistor; the
minimum value of the resistor 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
input’s last state preventing “floating” inputs and eliminating the
need for pullup/down resistors.
