74AC20PC

Overview

The onsemi 74AC20PC is a dual 4-input NAND gate manufactured using AC CMOS technology. It operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature from -40°C to +85°C. The device features outputs capable of sourcing and sinking 24mA. Propagation delays are specified at 10ns maximum for high-to-low transitions and 8ns maximum for low-to-high transitions at 5.0V. Input leakage current is limited to 1.0µA, with quiescent supply current capped at 20.0µA.
