Product Overview: MM74HC126MTC from ON Semiconductor

The MM74HC126MTC is a high-speed, quad bus buffer gate with 3-state outputs, designed and manufactured by ON Semiconductor. It is part of the 74HC series, which is well-known for its high-speed CMOS technology. This product is specifically tailored for driving bus lines or buffer memory address registers, making it a versatile component for a wide range of digital applications.

The device features four independent buffer gates, each with a separate output enable input. When the output enable (OE) input is low, the corresponding gate passes the input data to the output. Conversely, when OE is high, the output is in a high impedance state, which effectively isolates the bus line. This 3-state output configuration is crucial for preventing bus contention and allows for multiple devices to share a common bus line without interference.

The MM74HC126MTC operates over a wide voltage range of 2V to 6V, providing compatibility with a variety of logic levels and making it suitable for interfacing with both TTL and CMOS circuits. This flexibility ensures that the device can be integrated into mixed-voltage systems without additional level-shifting hardware, simplifying design and reducing overall system cost.

Packaged in a TSSOP-14 (Thin Shrink Small Outline Package), the MM74HC126MTC offers a compact footprint suitable for space-constrained applications. Its small size, combined with the high level of integration, allows for efficient use of board space in complex circuits.

With its fast propagation delay and low power consumption, the MM74HC126MTC is an excellent choice for high-speed digital systems. It is characterized for operation from -40°C to +85°C, ensuring reliable performance across a broad range of environmental conditions. ON Semiconductor's commitment to quality and performance makes the MM74HC126MTC a reliable component for designers looking to implement robust digital logic systems.

In summary, the MM74HC126MTC from ON Semiconductor is a feature-rich, high-speed quad bus buffer that offers designers a combination of performance, versatility, and reliability, making it an ideal choice for a variety of digital applications.
