What is the function of Pin 1 (A)? Pin 1 (A) is one of the input pins for the AND gate. It accepts a logic high (1) or low (0) signal. What is the function of Pin 2 (B)? Pin 2 (B) is the second input pin for the AND gate. Similar to Pin 1, it accepts either a high or low logic level. What is the purpose of Pin 3 (GND)? Pin 3 is the ground connection for the device. It must be connected to the system ground for proper operation. What does Pin 4 (Y) represent? Pin 4 (Y) is the output pin for the AND gate. The output will be high (1) only if both inputs (A and B) are high. What should I connect Pin 5 (Vcc) to? Pin 5 is the power supply input. It should be connected to a voltage source within the operating range of 2V to 5.5V. What happens if I leave the GND pin unconnected? If the GND pin (Pin 3) is unconnected, the device will not function, as there will be no reference ground for the logic signals. What type of logic operation does the SN74AHC1G08DBVR perform? It performs a 2-input AND operation, where the output is high only when both inputs are high. Can I use this part in a 5V system? Yes, the SN74AHC1G08DBVR is fully compatible with 5V systems, as it operates within a range of 2V to 5.5V. What is the maximum voltage I can apply to Pin 5 (Vcc)? The maximum voltage that can be applied to Pin 5 (Vcc) is 5.5V.What happens if I exceed the voltage range on Vcc?
Exceeding the voltage range (more than 5.5V) may damage the IC permanently.What is the maximum current draw from the Vcc pin?
The current draw is minimal; typical supply current is around 1 µA in the low-power mode.Can the output voltage on Pin 4 (Y) be used to drive other devices directly?
Yes, the output can drive standard CMOS logic gates or other low-power devices.What is the output logic level when both inputs are low?
When both inputs (A and B) are low (0), the output (Pin 4) will be low (0) as well.What is the delay time for the output to change?
The typical propagation delay (tpd) is 4 ns at Vcc = 5V, Ta = 25°C.Can the SN74AHC1G08DBVR be used in high-speed circuits?
Yes, it is suitable for high-speed circuits, thanks to its low propagation delay.What happens if I connect Pin 4 (Y) to ground?
If Pin 4 (Y) is connected to ground, the output will always be at a low logic level (0), irrespective of the input states.Is the SN74AHC1G08DBVR suitable for use in a low-voltage system?
Yes, the device is suitable for low-voltage systems, as it operates between 2V and 5.5V.What is the typical use case for the SN74AHC1G08DBVR?
