Product Description
Pericom Semiconductor’s PI74LPT series of logic circuits are produced USING the Company’s advanced 0.6 micron CMOS
technology, achieving industry leading speed grades.
The PI74LPT16240 is an inverting 16-bit buffer/line driver designed
for applications driving high-capacitance loads and low impedance
backplanes. This high-speed, low power device offers bus/backplane
interface capability and a flow-through organization for ease of
board layout. This device is designed with three-state controls to
operate in a Quad-Nibble, Dual-Byte, or a single 16-bit word mode.
The PI74LPT16240 can be driven from either 3.3V or 5.0V devices
allowing this device to be used as a translator in a mixed
3.3/5.0V system.

Propagation Delays and Enable/Disable times should be degraded by 20%.
2. See test circuit and wave forms.
3. Minimum limits are guaranteed but not tested on Propagation Delays.
4. This parameter is guaranteed but not production tested.
5. Skew between any two outputs, of the same package, switching in the same direction. This parameter is guaranteed by design.
