74HC04D,653

The 74HC04D,653 is a hex inverter integrated circuit (IC) manufactured by Nexperia, which is part of the 74HC (High-speed CMOS) logic family. This IC is designed to perform logical inversion on digital signals, meaning it takes an input signal and outputs the opposite logic level. Here’s a detailed description of its features and specifications:

General Description:

• Type: Hex Inverter
• Function: The 74HC04D contains six independent inverters, each capable of inverting a single input signal. This makes it useful for a variety of digital logic applications where signal inversion is required.

Pin Configuration:

• The IC typically comes in a 14-pin Dual In-line Package (DIP) or surface-mount package (SOIC), with the following pin configuration:
  • Pin 1 to Pin 6: Inputs for the first six inverters (A1 to A6).
  • Pin 2 to Pin 7: Outputs for the corresponding inverters (Y1 to Y6).
  • Pin 8: Ground (GND).
  • Pin 14: VCC (Power Supply).

Electrical Characteristics:

• Supply Voltage (VCC): The IC operates typically at a supply voltage range of 2V to 6V, making it compatible with various logic levels.
• Input Voltage Levels: The input high voltage (VIH) is typically around 2V (for a 5V supply), and the input low voltage (VIL) is around 0.8V.
• Output Voltage Levels: The output high voltage (VOH) approaches VCC, while the output low voltage (VOL) is close to ground.
• Propagation Delay: The typical propagation delay time (the time it takes for an input change to affect the output) is around 10-15 ns at 5V, which indicates the speed of the device.
