• Power Down Protection Provided on Inputs and Outputs

• Balanced Propagation Delays

• Designed for 4.5 V to 5.5 V Operating Range

• Low Noise: VOLP = 1.6 V (Max)

• Pin and Function Compatible with Other Standard Logic Families

• Latchup Performance Exceeds 300 mA

• ESD Performance:

Human Body Model > 2000 V;

Machine Model > 200 V

• Chip Complexity: 304 FETs or 76 Equivalent Gates

• Pb−Free Packages are Available*

APPLICATION NOTES

• Do not force a signal on an I/O pin when it is an active output, damage may occur.

• All floating (high impedance) input or I/O pins must be fixed by means of pullup or pulldown resistors or bus terminator ICs.
