ETC 74LCX07MX

Revised July 2001
74LCX07
Low Voltage Hex Buffer with Open Drain Outputs
General Description
Features
The LCX07 contains six buffers. The inputs tolerate voltages up to 7V allowing the interface of 5V systems to 3V
systems.
■ 5V tolerant inputs
The outputs of the LCX07 are open drain and can be connected to other open drain outputs to implement active
HIGH wire AND or active LOW wire OR functions.
The 74LCX07 is fabricated with advanced CMOS technology to achieve high speed operation while maintaining
CMOS low power dissipation.
■ 2.3V–5.5V VCC specifications provided
■ 2.9 ns tPD max (VCC = 3.3V), 10 µA ICC max
■ Power down high impedance inputs and outputs
■ +24 mA output drive (VCC = 3.0V)
■ Implements patented noise/EMI reduction circuitry
■ Latch-up performance exceeds 500 mA
■ ESD performance:
Human body model > 2000V
Machine model > 200V

Note 1: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated
at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the Absolute Maximum Ratings. The Recommended Operating Conditions table will define the conditions for actual device operation.
Note 2: IO Absolute Maximum Rating must be observed.
Note 3: Unused inputs must be held HIGH or LOW. They may not float.
