Logic Block Diagram

Product Description

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

The PI74ALVCH162244 is an non-inverting 16-bit buffer/driver designed for low voltage 2.3V to 3.6V VCC operation.

The 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 device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides non-inverting 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 VCC through a pullup resistor in which the minimum value is determined by the current-sinking capability of the driver.

The PI74ALVCH162244 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.
