Quiescent current is 2 µA max, which matters for battery-backed or always-on sections where the inverter sits idle between transactions. The input logic levels are 0.5 V to 1.8 V low and 1.5 V to 4.2 V high across the supply range — the wide low threshold means a 3.3 V signal driving a 5 V-powered inverter still registers a valid low without a level shifter ahead of the input. ROHS3 compliant — no restricted substances above the threshold; the part ships with standard TI compliance documentation (RoHS, REACH) on request.","metaTitle":"SN74HC05PWR Texas Instruments 74HC Hex Inverter, Open Drain","metaDescription":"SN74HC05PWR hex inverter with open-drain outputs, 2V-6V supply, 20ns propagation delay at 6V.

The pinout and package are the same 14-TSSOP, but the HCS04's hysteresis changes the noise immunity and timing.

The open-drain version lets you wire multiple outputs together on a single pull-up resistor (wired-OR) or drive a load at a higher voltage than the logic supply, which a totem-pole output cannot do without a buffer."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74HC05PWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74HC05PWR when reusing this data.
