ON Semiconductor MC74HC126ADTR2 Quad Buffer

The MC74HC126ADTR2 is a high-performance, integrated circuit designed and manufactured by ON Semiconductor, a renowned leader in the semiconductor industry. This quad buffer/line driver is part of the HC family and is fabricated with silicon gate CMOS technology to achieve operating speeds similar to LSTTL, with the low power consumption of standard CMOS integrated circuits.

This device consists of four independent buffer/line drivers with 3-state outputs, each capable of driving bus lines or buffer memory address registers. The 3-state control gate operates as a two-input NOR such that if either nOE1 (output enable) or nOE2 (output enable) is high, the output is in the high impedance "Z" state. This feature allows for the disconnection of the outputs from the bus lines during power-off or bus contention situations.

The MC74HC126ADTR2 is capable of delivering robust performance with a supply voltage range from 2V to 6V, making it compatible with a wide range of applications and logic systems. The high noise immunity characteristic of 0.1 VCC (typical) and low power dissipation are significant advantages for power-sensitive designs.

Supplied in a TSSOP-14 package, the MC74HC126ADTR2 offers a compact footprint that is suitable for space-constrained applications. Its design ensures minimal quiescent current when the device is in the disabled state, contributing to energy efficiency in the overall system design. The device is also characterized for operation from -55°C to 125°C, allowing for use in a broad range of environmental conditions.

Applications for the MC74HC126ADTR2 include signal buffering and driving in computer systems, communication equipment, and data processing, where high-speed, low-power operation is essential. Its 3-state outputs make it particularly useful in bus-oriented systems where multiple devices need to share common bus lines.

ON Semiconductor's commitment to quality ensures that the MC74HC126ADTR2 meets strict industry standards for reliability and performance, making it a trusted choice for engineers and designers looking for a high-quality buffer/line driver solution.
