ON Semiconductor MC74ACT125DTR2G Description

The MC74ACT125DTR2G is a quintessential component designed and manufactured by ON Semiconductor, renowned for its high-quality electronic components. This particular device is a quad buffer that features non-inverting 3-state outputs and is a part of the high-speed CMOS ACT family. The buffer is engineered to interface between two different logic voltage levels, providing the necessary logic level translation for data transmission across distinct voltage domains.

Constructed in a compact TSSOP-14 (Thin Shrink Small Outline Package with 14 leads) package, the MC74ACT125DTR2G is designed for space-constrained applications where board real estate is at a premium. This package type is not only space-efficient but also offers excellent thermal performance, making it suitable for high-density circuit designs.

With its operating voltage range of 4.5V to 5.5V, the device is compatible with TTL (Transistor-Transistor Logic) levels, which makes it a versatile choice for interfacing with legacy systems as well as modern low-voltage logic circuits. The MC74ACT125DTR2G boasts a robust latch-up performance, meeting the JEDEC standard JESD17, which ensures reliable operation under a wide range of conditions.

The device's inputs tolerate voltages up to 5.5V, allowing direct interfacing with higher voltage logic levels without the risk of damage. This feature is particularly important in mixed-voltage systems, where signal integrity and protection are critical. Additionally, the MC74ACT125DTR2G offers a high drive capability, with outputs capable of sourcing or sinking 24 mA, providing sufficient current to drive multiple loads or long transmission lines.

Its fast propagation delay and transition times are characteristic of the ACT series, making the MC74ACT125DTR2G an ideal choice for high-speed data transmission applications. The 3-state outputs also allow for connection to a common bus, which can be controlled by the output enable pins, enhancing the flexibility of the device in complex digital systems.

In summary, the ON Semiconductor MC74ACT125DTR2G is a reliable and efficient quad buffer that offers high-speed operation, level translation capabilities, and a compact footprint, making it a valuable component for a diverse range of electronic applications.
