Overview
The NC7SZ125M5X is a single buffer with three-state output from onsemi’s Ultra-High Speed (UHS) series of TinyLogic. Fabricated with advanced CMOS technology, this device achieves ultra-high speed with high output drive while maintaining low static power dissipation over a broad VCC operating range of 1.65 V to 5.5 V. The inputs and output are high impedance above ground when VCC is 0 V, and the inputs can tolerate voltages up to 5.5 V independent of the VCC operating voltage. This makes the NC7SZ125M5X highly versatile for various logic translation and buffering applications.
