Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
DescriptionPericom Semiconductor's PI74ALVTC series of logic circuits are produced in the Company's advanced 0.35 micron CMOS technology, achieving industry leading speed.
The PI74ALVTC16244 buffer/driver is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.
The PI74ALVTC16244 can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides true outputs and symmetrical active-low output-enable (OE) inputs.
To ensure the high-impedance state during power up or power down, OE should be tied to Vdd through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The PI74ALVTC16244 offers both I/O Tolerant, PI74ALVTC16244 allows it to operate in mixed 1.8/3.6V systems, and "Bus Hold," which retains the data input's last state whenever the data input goes to high-impedance, preventing "floating" inputs and eliminating the need for pullup/ down resistors.
