SN74HC05APWRG4

Overview

The SN74HC05APWRG4 is a hex inverter integrated circuit from Texas Instruments, belonging to the HC CMOS logic family. It contains six independent inverters with open-drain outputs, performing the Boolean function Y = A in positive logic. The device operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a TSSOP-14 package. It functions reliably across an operating temperature range of -40°C to +85°C. Key electrical specifications include a propagation delay of 20 ns, a high-level output current of -4 mA, and a low-level output current of 4 mA.
