Product Description

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 PI74ALVCH162260 is a 12-bit to 24-bit multiplexed D-type latch designed for 2.3V to 3.6 VCC operation. It is used in applications where two separate datapaths must be multiplexed onto, or demultiplexed from, a single data path.

Typical applications include multiplexing and/or demultiplexing address and data information in microprocessor or bus-interface applications. This device is also useful in memory-interleaving applications.

Product Features

• PI74ALVCH162260 is designed for low voltage operation

• VCC = 2.3V to 3.6V

• Hysteresis on all inputs

• Typical VOLP (Output Ground Bounce)

   < 0.8V at VCC = 3.3V, TA = 25°C

• Typical VOHV (Output VOH Undershoot)

   < 2.0V at VCC = 3.3V, TA = 25°C

• Bus Hold retains last active bus state during 3-STATE, eliminating the need for external pullup resistors
