It packages six independent inverter gates — each with a single input and a standard totem-pole output — into a 14-SOIC (3.90 mm width) surface-mount package. The part runs from a 4.75 V to 5.25 V supply rail, the classic 5 V TTL window, with a propagation delay of 22 ns at 5 V into a 15 pF load. Typical use: signal polarity inversion, logic-level buffering, or oscillator building blocks on 5 V digital PCBs. The commercial temperature range (0°C to 70°C) fits indoor equipment, office peripherals, and bench test fixtures — not engine compartments or outdoor telecom cabinets. ## Supply rail and timing — what the ratings mean for your BOM The 4.75 V to 5.25 V supply is tight — no margin for a droopy 5 V rail. If your system runs a regulated 5 V bus, this part fits. The 22 ns propagation delay at 5 V, 15 pF sets the clock-to-output ceiling for a single gate. In a daisy-chained inverter string for a ring oscillator or a clock buffer, that delay accumulates across six gates. The 12 mA quiescent current (max) is the total draw for all six channels; on a mixed-logic board with a dozen 7400-family parts, that quiescent sum adds up on the 5 V regulator budget. ## Lifecycle — active, no LTB concern The SN7404D carries an Active lifecycle status. The ROHS3 compliance covers current European and global RoHS exemptions — no special handling or exemption expiry to track.","metaTitle":"SN7404D Hex Inverter, 14-SOIC, 22ns @ 5V, Active","metaDescription":"Texas Instruments SN7404D hex inverter in 14-SOIC, 4.75V–5.25V supply, 22ns prop delay, 0°C–70°C.

A functional alternative in the same 14-SOIC footprint is the 74HCS04 from the 74HCS series, which adds Schmitt-trigger inputs and operates from 2 V to 6 V with a wider -40°C to 125°C temperature range. The 74ALS11 is a triple 3-input AND gate, not a direct inverter replacement.
