The 74AHC1G126DBVRE4 is a single-pole double-throw (SPDT) switch integrated circuit from the Texas Instruments category of programmable logic ICs. The part is based on a high speed CMOS logic family, usable between a voltage range of 1.65V to 3.6V. This device is categorized under logic buffers, drivers, receivers, and transceivers, and is designed to switch between two voltage states, 1 and 0. With its wide operating range, logic input hysteresis, and low propagation delay, this device can be used in a variety of rugged applications, from medical equipment and computer graphics controllers to smart meters and industrial control systems.

In terms of its applications, the 74AHC1G126DBVRE4 is ideally used as a level shifter, or as a fast, wide-range logic level multiplexer/demultiplexer, or as a bus selector. It can also be used as a latch and can switch voltages up to 24V. The logic family is designed for both power and speed and can easily switch between supply voltages of 1.65V and 3.6V. This switch is capable of multiplexing 32 data bits when used with a 4-bit address.

The 74AHC1G126DBVRE4 is made up of four pins, including a ground pin (GND), an input pin (A, B), and two output pins (Y, Z). The A and B pins, the input pins, are connected to the logic and can accept logic inputs ranging from 1.65V to 3.6V. Both A and B pins must have the same voltage level, while the output pins (Y,Z) display the opposite voltage level. For example, if the input pin is at a 1V level, the output pin will be at a 0V level and vice versa.

The 74AHC1G126DBVRE4 features low propagation delays, low switch point hysteresis, Schmitt-trigger action, low power dissipation, low on-state resistance, and balanced switching action. In addition to its CMOS-compatible logical levels, it also features a standby supply current of 0.1uA and a minimum off-state output current of ± 0.4mA. The minimum input voltage of 1.65V and maximum input current of 0.4mA makes it ideal for use in many applications. Additionally, the maximum operating temperature is specified at +85°C.

The 74AHC1G126DBVRE4 is widely used in a large range of devices, such as LCD screens, satellites and digital audio receivers. It is also used in data selectors, field-programmable gate arrays (FPGAs), high-speed frequency dividers and data buses. The wide operating range feature of the device allows it to be used in many applications requiring logic level switching. This part is available in a variety of package sizes, including the TQFP-44 and the SOIC-16.

Overall, the 74AHC1G126DBVRE4 is a logic buffer, driver, receiver, and transceiver IC from the Texas Instruments programmable logic ICs family. It is an SDT switch with four pins, including two input pins and two output pins. It is designed to switch between two voltage levels with a wide operating range and multiple features, including low propagation delays, low switch point hysteresis, and others. It is ideal for switching and multiplexing applications, and is used in a range of devices such as LCD screens, satellites and data selectors.
