PI74ALVCH32374

32-Bit Edge Triggered D-Type Flip-Flop

with 3-State Outputs

Product Features

ProductDescription

Pericom Semiconductors PI74ALVCH series of logic circuits are

produced using the Companys advanced 0.5 micron CMOS

technology, achieving industry leading speed.

• PI74ALVCH32374 is designed for low voltage operation

• V = 2.3V to 3.6V

• Typical V

(Output Ground Bounce)

OLP

This 32-bit edge-triggered D-type flip-flop is designed for 2.3V to

< 0.8V at V = 3.3V, T = 25°C

3.6V V operation.

• Typical V

(Output V Undershoot)

OHV

The PI74ALVCH32374 is particularly suitable for implementing

buffer registers, I/O ports, bidirectional bus drivers, and working

registers. This device can be used as four 8-bit flip-flops or two

outputs in either a normal logic state (high or low logic levels) or a

high-impedance state. In that state, the outputs neither load nor

drive the bus lines significantly. The high-impedance state and the

increased drive provide the capability to drive bus lines without

• Bus Hold retains last active bus state during 3-State

eliminating the need for external pullup resistors

• Industrial operation at 40°C to +85°C

• Packages available:

96-ball, 13.5mm x 5.5mm x 1.4mm low profile fine

pitch ball grid array, LFBGA(NB)

To ensure the high-impedance state during power up or power

down, OE should be tied to V through a pullup resistor; the

minimumvalue of the resistor is determined by the current-sinking

capability of the driver.

Active bus-hold circuitry is provided to hold unused or floating

data inputs at a valid logic level.
