74HC126N Buffers, Drivers, Receivers, Transceivers by Nexperia Semiconductor (NXP) (Obsolete Lifecycle)

Description

The 74HC126N is a quad buffer from NXP, designed for digital logic applications. It's a non-inverting buffer with three-state output, allowing it to be used as an open-drain or push-pull device. This IC contains four independent buffers, each capable of driving a load capacitance of up to 50 pF. The buffers have a high input impedance and can operate at frequencies up to 100 MHz. The 74HC126N is commonly used in digital systems where level translation or buffering is required. Its low power consumption and high speed make it suitable for use in a wide range of applications, including industrial control systems, automotive electronics, and consumer devices.

Package

The package type of 74HC126N is PDIP-14 (Plastic Dual In-Line Package, 14 pins).

Pinout

The 74HC126N is a 14-pin DIP (Dual In-Line Package) buffer IC from NXP. It's a non-inverting buffer with four independent buffers, each capable of driving one bit of data.

Here's the pin count and function:

• Pin 1: VCC (5V power supply)
• Pins 2-3: A (input)
• Pins 4-5: Y (output)
• Pins 6-7: B (input)
• Pins 8-9: Z (output)
• Pins 10-11: C (input)
• Pins 12-13: W (output)
• Pin 14: GND (ground)

Each buffer has a high-impedance input and can be used to drive a load, such as an LED or another IC. The device operates from a single +5V power supply and is compatible with the 74HC logic family.

Manufacturer

The manufacturer of the 74HC126N is NXP. NXP is a leading semiconductor company that specializes in the design, manufacture, and marketing of semiconductors, such as microcontrollers, radio frequency identification (RFID) products, analog and power management devices, and others. The company was previously known as Philips Semiconductors until 2006 when it merged with Freescale Semiconductor to form NXP.
