Note: 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.

Pericom Semiconductor's PI74ALVCH series of logic circuits are produced in the Company's advanced 0.5 micron CMOS technology, achieving industry leading speed.

The PI74ALVCH162827 is a 20-bit non-inverting buffer/driver designed for 2.3V to 3.6V VCC operation.

The 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 of PI74ALVCH162827 must both be low for the corresponding Y outputs to be active. If either output-enable input is HIGH, the outputs of that 10-bit buffer section are in the high-impedance state.

The outputs, PI74ALVCH162827 is designed to sink up to 12mA, include 26W resistors to reduce overshoot and undershoot.

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 PI74ALVCH162827 is determined by the current-sinking capability of the driver.

The PI74ALVCH162827 has "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.
