Product Overview: CD74HCT126E Quad Buffer/Line Driver from Texas Instruments

The CD74HCT126E is a high-performance CMOS Quad Buffer/Line Driver designed by the renowned semiconductor manufacturer, Texas Instruments. This integrated circuit is specifically engineered to provide high-speed and high-drive capabilities while maintaining low power consumption, making it an ideal choice for a wide range of digital applications.

Featuring four independent buffer/line drivers with 3-state outputs, the CD74HCT126E is capable of driving bus lines or buffer memory address registers. Each buffer has its own output enable pin, allowing for greater flexibility and control in various circuit designs. When the output enable (OE) input is high, the output is in a high-impedance state, which effectively isolates the output from the bus line.

The device operates at a voltage range of 4.5V to 5.5V, which aligns with standard TTL levels, and is thus easily interfaced with TTL logic components. The CD74HCT126E is characterized for operation from -55°C to 125°C, ensuring reliable performance across a wide range of environmental conditions.

Key features of the CD74HCT126E include:

• Logic Type: Quad Buffer/Line Driver with 3-state outputs
• Supply Voltage: 4.5V to 5.5V, compatible with TTL levels
• Independent Channels: 4
• Output Enable Control: Separate OE for each channel
• Temperature Range: -55°C to 125°C
• Package: DIP-14 (Dual In-line Package with 14 pins)
• Typical Power Dissipation: Low
• High Noise Immunity: Yes

With its robust design and high noise immunity, the CD74HCT126E is suitable for interfacing with a variety of digital systems, such as computers, communication equipment, and data processing units. The device's packaging is a standard DIP-14, which is widely used in through-hole PCB designs.

In summary, the CD74HCT126E from Texas Instruments is a versatile and reliable component that offers the functionality of four independent buffers with the added advantage of 3-state outputs. Its compatibility with TTL logic levels and low power dissipation make it a go-to choice for designers looking to create efficient and high-performing digital circuits.
