The 74LS04 is a member of the 74LSxx series of integrated circuits (ICs) and is specifically a hex inverter gate. It contains six independent inverter gates, each performing the logical operation of inverting the input signal. Here are some key features and specifications of the 74LS04:
Type: Hex Inverter Gate.
Number of Gates:
The 74LS04 contains six individual inverter gates.
Logic Symbol:
The logic symbol for an inverter gate is often represented by a triangle, and its truth table is such that it produces the complement (inverse) of the input signal.
Input Voltage Range:
The 74LS04 typically operates with TTL (Transistor-Transistor Logic) levels, and the input voltage high (VIH) is usually specified as a voltage above a certain threshold, while the input voltage low (VIL) is specified as a voltage below a certain threshold.
Output Voltage Range:
The output voltage levels are compatible with TTL logic, providing a high voltage (VOH) close to the supply voltage and a low voltage (VOL) close to ground.
Propagation Delay:
The propagation delay is the time it takes for a change in the input to result in a change at the output and is typically specified in nanoseconds.
Supply Voltage (VCC):
The operating supply voltage for the 74LS04 is typically in the range of 4.75V to 5.25V.
Operating Temperature Range:
The operating temperature range is typically specified, and the 74LS04 is designed to operate within a certain temperature range.
Package:
The 74LS04 is commonly available in a variety of packages, such as DIP (Dual In-line Package) and SOP (Small Outline Package).
Applications:
The 74LS04 is used in digital electronic circuits for tasks such as signal inversion, level shifting, and logical operations.
