SN74HC74N (Copy)

The SN74HC86N is a high-performance CMOS quad 2-input exclusive-OR (XOR) gate IC. Manufactured by Texas Instruments, this IC features four independent XOR gates, each capable of performing the Boolean function Y = A ⊕ B (where ⊕ denotes XOR). The SN74HC86N is designed for use in digital circuits where phase difference detection, inversion, or buffering of signals is required.

Key Features:

1. Quad 2-Input XOR Gates:
   • The IC contains four XOR gates, each with two inputs and one output.
   • The XOR function outputs a high (1) signal when the inputs are different (A = 0, B = 1 or A = 1, B = 0) and a low (0) signal when the inputs are the same (A = 0, B = 0 or A = 1, B = 1).
2. CMOS Technology:
   • The SN74HC86N utilizes CMOS technology, resulting in low power consumption and high noise immunity.
   • This makes the IC suitable for applications requiring low power and high reliability.
3. Wide Operating Voltage Range:
   • The IC can operate within a wide voltage range of 2V to 6V, providing flexibility in different power supply environments.
4. High Speed and Low Propagation Delay:
   • The XOR gates have a maximum propagation delay of 21ns (typical), ensuring fast data processing in digital systems.
5. Buffered Inputs:
   • The inputs of the XOR gates are buffered, providing improved noise immunity and signal integrity.
6. Fan-Out Capability:
   • The SN74HC86N can drive up to 10 LSTTL loads, providing sufficient fan-out for most digital applications.
7. TTL-Compatible Logic Levels:
   • The IC operates with TTL-compatible logic levels, making it easy to interface with other TTL devices in digital circuits.
8. 14-Pin PDIP Package:
   • The IC is packaged in a 14-pin plastic dual-in-line package (PDIP), which is suitable for through-hole mounting on printed circuit boards.
9. Operating Temperature Range:
   • The SN74HC86N can operate within a temperature range of -40°C to +85°C, ensuring reliable performance in a variety of environments.

Applications:

• Phase Difference Detection:
  • The XOR function can be used to detect phase differences between two input signals.
• Inversion/Buffering:
  • The XOR gates can be configured to create inverters or buffers for digital signals.
• Digital Logic Circuits:
  • The SN74HC86N can be used in various digital logic circuits, such as counters, decoders, and mux/demux circuits.

In summary, the SN74HC86N is a versatile and reliable quad 2-input XOR gate IC with CMOS technology, a wide operating voltage range, high speed, and TTL-compatible logic levels. Its buffered inputs, fan-out capability, and compact PDIP package make it suitable for a wide range of digital systems and applications.
