Description
The SN74HC126DR has a low power consumption characteristic while providing significant drive capability, making it suitable for a variety of digital applications. Its inputs are compatible with TTL logic levels, and its outputs can directly drive CMOS loads. The device comes in a small outline package (SOIC), marked as "DR" in the part number, which is ideal for space-constrained applications. This component is commonly used in digital circuits requiring signal buffering, voltage conversion, or isolated signal lines.
Equivalent
- NXP 74HC126D
- ON Semiconductor MC74HC126AD
- STMicroelectronics M74HC126B1R
- Fairchild Semiconductor (now ON Semiconductor) 74HC126MTC
These alternatives are functionally similar and can be used as substitutes, but always verify pin compatibility and electrical specifications in the datasheets.
Features
1. High-Speed Operation: It belongs to the HC (High-Speed CMOS) family, ensuring fast switching speeds and low propagation delay.
2. 3-State Outputs: Each output can be independently controlled to be in a high, low, or high-impedance state, facilitating bus-oriented applications.
3. Wide Operating Voltage: Compatible with a range of supply voltages, typically from 2V to 6V, allowing for flexible use in different systems.
4. Low Power Consumption: The CMOS technology ensures minimal power dissipation even at high frequencies.
5. Input Compatibility: Inputs are TTL-compatible, making it suitable for interfacing with TTL logic levels.
6. High Noise Immunity: Improved noise margins due to the CMOS design.
7. Package: Available in a SOIC-14 package which is ideal for surface-mount applications.
These features make SN74HC126DR suitable for applications requiring reliable signal buffering and bus interfacing capabilities.
Pinout
Key specifications:
- Pin Count: 14 pins
- Function:
- Inputs: 4 data inputs (one for each buffer)
- Outputs: 4 three-state outputs
- Output Enable Pins: 4 output enable controls (one for each buffer)
The SN74HC126DR operates efficiently in both high-speed and low-power applications, making it suitable for a wide range of digital applications where buffering and signal driving with selectable output states are necessary. Each buffer in the device has an individual enable pin that controls the output state, allowing for versatile interfacing and signal management.
