Propagation delay is 20 ns typical at 6V with a 50 pF load, which sets the practical data rate ceiling for the open-drain bus; at lower supply voltages the delay increases, so budget extra margin if running at 2V. Quiescent current is just 2 µA max — the part draws almost nothing when the outputs are static, which matters for always-on logic in battery-powered equipment where every microamp counts. Input logic thresholds are 0.5V to 1.8V for low and 1.5V to 4.2V for high, compatible with both 3.3V and 5V CMOS families without extra glue. The SN74HC05NSR comes in a 14-SOIC package with 5.30 mm body width (the wider SOIC-14 variant, not the narrow 3.90 mm).","metaTitle":"SN74HC05NSR Texas Instruments 74HC Hex Inverter, Open-Drain","metaDescription":"TI SN74HC05NSR hex inverter with open-drain outputs, 6 circuits, 2V-6V supply, -40°C to 85°C, 14-SOIC.
