ON Semiconductor MC74VHCT125ADTR2G Quadruple Bus Buffer Gates with 3-State Outputs

The MC74VHCT125ADTR2G from ON Semiconductor is a high-performance, quadruple bus buffer gate featuring 3-state outputs designed to interface between two different voltage domains. This integrated circuit is part of the high-speed CMOS VHCT family and is fabricated with silicon gate CMOS technology. It boasts a significant advantage in power and speed performance over standard CMOS logic types while retaining the low power dissipation of CMOS.

This device is particularly useful in driving bus lines or buffer memory address registers due to its high drive and wide voltage range capability. Each of the four gates is equipped with a separate output enable input, which controls the 3-state output. When the output enable (OE) input is high, the output is in a high-impedance state, which effectively disconnects the output from the bus. This allows for multiple devices to be connected to the same bus line without interference.

The MC74VHCT125ADTR2G operates at a voltage range of 4.5V to 5.5V, which allows it to interface with 5V logic systems while maintaining the speed of CMOS technology. It is also TTL input compatible, allowing direct interfacing with TTL logic levels without the need for additional components. The device features a balanced propagation delay and transition times, which provides reliable, high-speed operation.

ON Semiconductor has packaged this device in a TSSOP-14 (Thin Shrink Small Outline Package), which offers a compact footprint for space-constrained applications. The MC74VHCT125ADTR2G is provided in tape and reel packaging, making it suitable for automated assembly processes and mass production.

With its robust design and compatibility with multiple logic levels, the MC74VHCT125ADTR2G is an excellent choice for a variety of applications, including bus driving, buffer memory addressing, and interfacing in systems that require high-speed, low-power operation.

Overall, the MC74VHCT125ADTR2G from ON Semiconductor represents a reliable and efficient solution for designers looking to optimize their digital systems for performance and power consumption.
