• Low Power Dissipation: ICC = 4µA (Max) at TA = 25°C
• TTL–Compatible Inputs: VIL = 0.8 V; VIH = 2.0 V
• Power Down Protection Provided on Inputs and Outputs
• Balanced Propagation Delays
• Designed for 2V to 5.5V Operating Range
• Low Noise: VOLP = 0.8V (Max)
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300mA
• ESD Performance: HBM > 2000V; Machine Model > 200V
