SN74AHC126D is a quad buffer drive for use in high-performance memory address, address and data bus systems. It is a 3V-5V logic device that performs the function of inverting and non-inverting buffer. SN74AHC126D drivers feature high output current capability and guaranteed minimum output drive capabilities. It features high noise immunity for compatibility with modern crowded high-speed differential bus environments. SN74AHC126D can provide both buffering and signal conditioning functions to meet the requirements of high-frequency applications.

SN74AHC126D belongs to MOS logic family and is compatible with most digital logic families like TTL, ECL, C-MOS and so on. It has two logic states connected to the two power supply rails Vcc and GND. Vcc represents a logic high whereas GND represents a logic low. This device is available in both Through-Hole and Surface Mount packages.

The SN74AHC126D is a high performance quad buffer driver. It has four independent input/output buffers, each consisting of two separate high-drive input stages and two high-drive output stages. The two input stages provide two different logic levels: logic high and logic low. The two output stages will open-drain outputs to either logic high or logic low depending upon the logic level of their respective inputs. Inputs are protected from damage caused by either overvoltage or driven beyond their specified power ratings.

In addition to its four buffer output stages, the SN74AHC126D also has an enable pin which can be used to enable or disable the entire device. This pin allows the device to be disabled whenever the logic levels of its inputs are not valid. This pin can also be used to enable and disable the output buffers independently.

The SN74AHC126D is a powerful device design for use in a wide range of applications such as memory address, address and data bus systems. It is also suitable for applications used in telecommunications and computing such as video/memory buses, router interconnects or as level translators for UARTs, SATA and Fibre Channel. In addition, it can be used for level shifting and inverting applications that require both TTL and CMOS logic levels.

When used as a buffer driver, the SN74AHC126D enables the system to drive larger distances over significant capacitance. The device provides four independent buffer output stages capable of driving up to 24mA at 3.3V. In addition, the device has guarantee minimum output drive capability of 24mA at 3.3V and 12mA at 5V. These outputs are also capable of driving inductive loads such as relays and solenoids.

The SN74AHC126D is an economical addition to systems which require multiple logic buffer outputs. It has a high noise immunity and is capable of driving loads over large capacitive distances. The device also has a guaranteed minimum output drive capability and is available in both Through-Hole and Surface Mount packages.
