Frequently Asked Questions
What is the supply voltage range for SN74HC02D?
The SN74HC02D operates from 2V to 6V supply voltage, making it compatible with both 3.3V and 5V logic systems. At 5V VCC, it achieves maximum speed (7ns propagation delay). At lower voltages, speed decreases but power consumption is reduced.
Is SN74HC02D compatible with TTL logic levels?
Yes, SN74HC02D has TTL-compatible input thresholds when operating at 4.5V-5.5V VCC. Input high threshold (VIH) is 1.5V minimum. For guaranteed TTL compatibility at 5V, consider the SN74HCT02D variant which has specified TTL-level thresholds.
What is the pinout of SN74HC02D?
SN74HC02D follows the standard 7402 pinout: Gate 1 inputs at pins 2,3 output pin 1; Gate 2 inputs 5,6 output 4; Gate 3 inputs 8,9 output 10; Gate 4 inputs 11,12 output 13. Pin 7 is GND, pin 14 is VCC.
What is the power consumption of SN74HC02D?
Static power consumption is extremely low at 20µA max quiescent current (VCC=6V). Dynamic power depends on frequency: approximately 23µW per gate per MHz at 5V. At 1MHz typical operation, total power is under 1mW, making it ideal for battery-powered designs.
