Product Description

Pericom Semiconductor’s PI74LVTC series of logic circuits are

produced using the Company’s advanced CMOS technology,

achieving industry leading speed.

The PI74LVTC16244 is a non-inverting 16-bit buffer and line

the capability of interfacing to the 5V system environment. This

buffer/driver is designed specifically to improve both the perfor-

mance 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.

the device is in the high-impedance state. To ensure the high-

impedance state above 1.5V, 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.

power is off, preventing the backflow of damaging current through

the device. Power-up/down 3-state places the outputs in the high-

impedance state during power up or power down, preventing driver

conflict.
