16-Bit Buffer/Driver

with 3-State Outputs

Product Features

Product Description

• The PI74VCX Family is designed for low voltage

operation, CD = 1.8V to 3.6V

• 3.6V Tolerant Inputs and Outputs

Pericom Semiconductor’s PI74VCX series of logic circuits is

produced in the Company’s advanced 0.35 micron CMOS

technology, achieving industry leading speed.

• Supports Live Insertion

• Balanced Drive, ±24mA

• Uses patented Noise Reduction Circuitry

• Typical VOLP (Output Ground Bounce) <0.6V

at VDD = 2.5V, TA = 25ºC

• Typical VOHV (Output VOH Undershoot) < -0.6V

at VDD = 2.5V, TA = 25ºC

• Power-Off high impedance inputs and outputs

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

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 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 Vcc through a pullup resistor; the

minimum value of the resistor is determined by the current-sinking

capability of the driver.

• Packages available:

– 48-pin 240 mil wide plastic TSSOP (A)

The PI74VCX family is I/O Tolerant, allowing it to operate in

1.8/3.6V systems.

– 48-pin 300 mil wide plastic SSOP (V)
