The SN74HC125N is a quad buffer/driver with three-state outputs, designed by Texas Instruments. It belongs to the 74HC (High-speed CMOS) family, which is known for its high-speed operation and low power consumption. Here’s a detailed description of its features and specifications:
General Description:
- Functionality: The SN74HC125N contains four independent buffer/driver circuits, each with a three-state output. This means that each output can be in one of three states: high (logic 1), low (logic 0), or high-impedance (Z). The high-impedance state allows for multiple outputs to be connected to a common bus without interference.
- Logic Levels: It operates with standard CMOS logic levels, making it compatible with a wide range of digital circuits.
Pin Configuration:
- The device is typically available in a 14-pin Dual In-line Package (DIP) or surface-mount packages. The pins are arranged in two rows, with each pin serving a specific function:
- Inputs: Each of the four buffer circuits has an input pin (A1, A2, A3, A4).
- Outputs: Corresponding to each input, there are output pins (Y1, Y2, Y3, Y4).
- Enable Pins: Each buffer has an associated enable pin (OE1, OE2, OE3, OE4) that controls the output state. When the enable pin is high, the output is in a high-impedance state; when low, the output reflects the input state.
Electrical Characteristics:
- Supply Voltage (Vcc): The SN74HC125N operates over a supply voltage range of 2V to 6V, making it versatile for various applications.
- Input Voltage Levels: The input voltage levels are compatible with TTL logic, allowing for seamless integration with other logic families.
- Output Drive Capability: The device can drive loads of up to 15 mA per output, making it suitable for driving LEDs, other logic gates, or small loads directly.
- Propagation Delay: The typical propagation delay is around 15 ns at 5V, which allows for high-speed data transmission in digital circuits.
Applications:
- Bus Drivers: The three-state outputs make it ideal for use in bus systems where multiple devices share the same data lines.
- Signal Isolation: It can be used to isolate different parts of a circuit, preventing interference and ensuring signal integrity.
- Level Shifting: The SN74HC125N can be used for level shifting between different voltage domains in mixed-voltage systems.
Package Information:
- The SN74HC125N is available in various package types, including:
- DIP-14: A standard dual in-line package suitable for through-hole mounting.
- SOIC-14: A small outline integrated circuit package for surface mounting.
Conclusion:
The SN74HC125N from Texas Instruments is a versatile and reliable quad buffer/driver that is widely used in digital electronics. Its combination of high-speed performance, low power consumption, and three-state outputs makes it an essential component in many applications, from simple logic circuits to complex digital systems.
