ON Semiconductor MC74HC126ADR2 Product Overview

The MC74HC126ADR2 is a high-performance integrated circuit manufactured by ON Semiconductor, known for its reliability and versatility in various electronic applications. This quadruple bus buffer gate with 3-state outputs is part of the high-speed CMOS family and is designed to operate with an input voltage range from 2V to 6V, making it suitable for interfacing with TTL levels.

Key Features

• Logic Type: Buffers & Line Drivers
• Number of Channels: 4
• Output Type: 3-State
• Input Voltage: 2V to 6V
• High Output Current: -7.8 mA, 7.8 mA
• Propagation Delay Time: 8ns at 6V
• Operating Temperature: -55°C to 125°C
• Mounting Type: Surface Mount
• Package / Case: SOIC-14

The MC74HC126ADR2 features four independent buffer gates, each with a 3-state output that can be used as a line driver or bus buffer. The 3-state outputs ensure that the device can be connected directly to a bus-structured system without causing any conflicts. When the output enable (OE) input is high, the output is in a high impedance state, which effectively isolates the bus line.

Applications

The versatility of the MC74HC126ADR2 makes it an ideal choice for a wide range of applications. It is commonly used in:

• Bus driving
• Memory address driving
• Input/Output port driving
• Buffering for data transmission systems

With its robust design, the MC74HC126ADR2 is also suitable for use in harsh environments, offering reliable performance over a wide range of operating temperatures.
