Product Description
Pericom Semiconductor’s PI74LCX series of logic circuits are produced in the Company’s advanced 0.6 micron CMOS technology achieving high speed while maintaining low power operation.
The PI74LCX541 is an 8-bit buffer/line driver designed for 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. This device offers a flow-through organization for ease of board layout.
The PI74LCX541 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/5.0V system.

Maximum Ratings
(Above which the useful life may be impaired. For user guidelines, not tested.)
Note:
Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the de­vice. This is a stress rating only and functional opera­tion of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

Notes:
1 . For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type. 2 . Typical values are at V
CC
= 3.3V, +25°C ambient.
3 . Per TTL driven input; all other inputs at VCC or GND.
