Unlike a standard push-pull output, an open-drain stage can only pull the output low (sink current) — the high level is set by an external pull-up resistor tied to whatever voltage the downstream logic needs. This is the standard method for level-shifting a 5 V logic output down to 3.3 V or up to 12 V, or for building a wired-OR bus where multiple outputs share a common pull-up. ## Supply range and speed — where the 74HC family lands Runs from 2 V to 6 V supply, drawing just 2 µA quiescent. The 20 ns propagation delay at 6 V with a 50 pF load is typical for the 74HC family — fast enough for most control and interface logic below 20 MHz, but not for high-speed clock distribution. ## Package and board fit 14-SOIC with a 3.90 mm body width — the narrow SOIC footprint that matches the industry-standard JEDEC MS-012 variation. The tube delivery means the parts come in anti-static tubes, not tape-and-reel; if your pick-and-place line is set up for tape, factor in a tube-to-tape conversion step or order the tape-and-reel variant (SN74HC05DR). The 1.75 mm seated height keeps it under most enclosure and mezzanine clearance limits.","metaTitle":"SN74HC05D Texas Instruments Hex Inverter, Open Drain","metaDescription":"SN74HC05D hex inverter with open-drain outputs. 2V-6V supply, 2 µA quiescent, 20ns prop delay.

The SN74HC05D has standard input thresholds (0.5 V to 1.8 V low, 1.5 V to 4.2 V high), while the HCS04 has hysteresis (1 V to 3 V low, 1.5 V to 4.2 V high). On a clean digital bus with fast edges, they swap directly. On a noisy or slow-rising signal, the HC05 may oscillate or double-trigger where the HCS04 would not.
