Product Features
16-Bit Inverting Buffer/Driver
with 3-State Outputs
Product Description
• The PI74VCX Family is designed for low voltage
operation, VDD = 1.8V to 3.6V
• 3.6V Tolerant Inputs and Outputs
• 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
• Packaging (Pb-free & Green available):
– 48-pin 240 mil wide plastic TSSOP (A)
The inverting 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 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.
The PI74VCX family is I/O Tolerant, allowing it to operate in
1.8/3.6V systems.
