74LCX126MX

The 74LCX126MX is a low-voltage CMOS buffer IC from onsemi, designed for general-purpose digital logic buffering. It contains four independent non-inverting buffer elements, each with a single-bit input and a 3-state output that can be placed in a high-impedance state for bus isolation. The device operates over a supply voltage range of 2V to 3.6V, making it suitable for low-voltage systems. Each output can sink or source up to 24mA, providing adequate drive for typical logic loads. The operating temperature range of -40°C to 85°C allows use in industrial and commercial environments.

The 74LCX126MX is offered in a 14-SOIC surface mount package with a body width of 0.154 inches (3.90mm). This compact footprint is suitable for automated assembly and space-constrained PCB designs. The 3-state output control enables multiple devices to share a common bus without contention. The device is latched-up proof and features ESD protection on all inputs and outputs.

Typical applications include signal buffering, line driving, memory address buffering, and microcontroller I/O expansion. The 74LCX126MX is a direct functional equivalent to the standard 74LCX126 logic family, providing a non-inverting buffer with 3-state outputs in a low-voltage, high-speed CMOS process.
