74VCX86
Low Voltage Quad 2-Input Exclusive-OR Gate with
3.6V Tolerant Inputs and Outputs
General Description
Features
The VCX86 contains four 2-input exclusive OR gates. This
product is designed for low voltage (1.2V to 3.6V) VCC
applications with I/O compatibility up to 3.6V
■ 1.2V to 3.6V VCC supply operation
The 74VCX86 is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining
low CMOS power dissipation.
■ 3.6V tolerant inputs and outputs
■ tPD
3.0 ns max for 3.0V to 3.6V VCC
■ Power-off high impedance inputs and outputs
■ Static Drive (IOH/IOL)
r24 mA @ 3.0V VCC
■ Uses patented noise/EMI reduction circuitry
■ Latchup performance exceeds JEDEC 78 conditions
■ ESD performance:
Human body model ! 2000V
Machine model ! 250V
■ Leadless Pb-Free DQFN package

Note 2: 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 3: IO Absolute Maximum Rating must be observed.
Note 4: Floating or unused inputs must be held HIGH or LOW.

Note 6: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL) or LOW-to-HIGH (tOSLH).
