2-input NOR gate 74HC1G02; 74HCT1G02
FEATURES
• Wide operating voltage:
2.0 to 6.0 V
• Symmetrical output impedance
• High noise immunity
• Low power dissipation
• Balanced propagation delays
• Very small 5 pins package
• Output capability: standard.
DESCRIPTION
The 74HC1G/HCT1G02 is a high
speed Si-gate CMOS device.
The 74HC1G/HCT1G02 provides the
2-input NOR function. The standard
output currents are half the values
compared to the 74HC/HCT02.
