SN74AHC05NSR TI Inverter | 6-Channel, Open Drain, 2V-5.5V

Product Overview

The SN74AHC05NSR from Texas Instruments is a high-performance hex inverter with open-drain outputs. It belongs to the AHC (Advanced High-Speed CMOS) family, offering a balance of speed and power consumption. The device contains six independent inverters, each with an open-drain output that can be connected to a pull-up resistor for wired-OR logic or level shifting. Operating from 2V to 5.5V, it is suitable for battery-powered and industrial applications. The open-drain outputs allow multiple outputs to be connected together to implement active-low wired-OR functions. The SN74AHC05NSR is available in a SOP-14 package, providing a compact solution for space-constrained designs.
