PI74LCX241
Fast CMOS 3.3V 8-Bit
Buffer/Line Driver
Product Features
ProductDescription
• FunctionallycompatiblewithFCT3,LVT,and
Pericom Semiconductor’s PI74LCX series of logic circuits are
produced using the Company’s advanced 0.6 micron CMOS
technology achieving high speed while maintaining low power
operation.
ThePI74LCX241isan8-bitbuffer/linedriverdesignedfor driving
high capacitive memory loads. With its balanced-drive
characteristics, this high-speed, low power device provides lower
ground bounce, transmission line matching of signals, fewer line
reflections and lower EMI and RFI effects. This makes it ideal for
driving on-board buses and transmission lines.
74 series 241 families of products
• Tri-State outputs
• 5V Tolerant inputs and outputs
• 2.0V-3.6VV supplyoperation
CC
• Balanced sink and source output drives (24 mA)
• Low ground bounce outputs
• Power Down High Impedance inputs and outputs
• Supports live insertion
The PI74LCX241 can be driven from either 3.3V or 5.0V devices
allowing this device to be used as a translator in a mixed
3.3V/5.0Vsystem.
