Each gate takes a single input and drives an open-drain output — the output transistor pulls low, but the high level is determined by an external pull-up resistor. This makes the part a wired-OR building block for bus arbitration, active-low interrupt consolidation, and level translation between 2V and 6V logic domains. Supply range covers 2V to 6V, and the quiescent current sits at 2 µA typical. Propagation delay is 20 ns at 6V into a 50 pF load. ## Open-drain output — what it buys you The open-drain output sinks 5.2 mA per channel. Multiple outputs can be tied together to a common pull-up resistor for wired-AND or wired-OR functions. ## Where it fits in a board Package is 14-TSSOP with 0.173\" body width and 4.40 mm pitch — a compact footprint for dense layouts. Surface-mount only; the tape-and-reel or cut-tape options suit both prototyping and production reels. For higher temperature or Schmitt-trigger inputs, the 74HCS04 or 74HCS14 peers offer -40°C to 125°C operation with integrated hysteresis. ## Active and available No last-time-buy or phase-out notices are in effect. The 74HC family is a mature logic series; second-source equivalents exist from multiple manufacturers, but the exact TI order code is the one to specify for BOM consistency.","metaTitle":"SN74HC05PWT 74HC Hex Inverter, Open Drain, 14-TSSOP","metaDescription":"TI SN74HC05PWT hex inverter with open-drain outputs. 2V-6V supply, 2 µA quiescent, 20 ns delay at 6V/50pF.

The output transistor can only sink current to ground; the high level is set by an external pull-up resistor. This allows wired-OR connections and level translation between different supply voltages within the 2V to 6V range."},{"question":"What is the difference between SN74HC05PWT and SN74HC05PWR?","answer":"The SN74HC05PWT and SN74HC05PWR are functionally identical — both are hex inverters with open-drain outputs in a 14-TSSOP package. The difference is the shipping medium: PWT is supplied in tape and reel (or cut tape), while PWR is also tape and reel but with a different reel diameter or quantity. For design fit, they are interchangeable."},{"question":"Can SN74HC05PWT be used as a level shifter?","answer":"Yes, because the open-drain output high level is set by the pull-up voltage, not the supply rail. You can drive the input from a 3.3 V logic signal and pull the output up to 5 V, translating the logic level. The input thresholds are compatible with 3.3 V logic at a 5 V supply."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74HC05PWT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74HC05PWT when reusing this data.
