That open-collector stage is the key feature: each output can sink up to 60 mA — enough to drive a small relay coil, an optocoupler LED, or a panel indicator without an external transistor. It also lets you wire multiple gate outputs together to form a wired-OR connection, useful for shared interrupt or status lines on a backplane. Supply voltage is a tight 4.75 V to 5.25 V, standard for 5 V TTL logic. The 9 ns propagation delay at 5 V with a 150 pF load keeps up with most board-level glue logic but won't stretch to high-speed clock trees. Operating temperature is 0°C to 70°C — commercial grade, so this is an indoor, controlled-environment part. ## Lifecycle and sourcing The SN74S38NS carries an Active product status and is ROHS3 compliant. For a BOM line that needs a 5 V open-collector NAND, this part is a straightforward fit — no end-of-life risk to plan around.","metaTitle":"SN74S38NS 74S Quad 2-Input NAND Gate, Open-Collector","metaDescription":"SN74S38NS 74S quad 2-input NAND gate with open-collector outputs, 60 mA sink, 9 ns delay at 5V, 150pF. 14-SOIC, 0-70°C.","metaKeywords":null},"attributes":{"series":"74S","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Series":"74S","Package":"Tube","Features":"Open Collector","Logic Type":"NAND Gate","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Number of Inputs":"2","Voltage - Supply":"4.75V ~ 5.25V","Number of Circuits":"4","Operating Temperature":"0°C ~ 70°C","Input Logic Level - Low":"0.5V","Supplier Device Package":"14-SO","Current - Output High, Low":"-, 60mA","Max Propagation Delay @ V, Max CL":"9ns @ 5V, 150pF"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.01","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.01000","currency":"USD"},{"qty":10,"price":"$2.70500","currency":"USD"},{"qty":25,"price":"$2.55200","currency":"USD"},{"qty":100,"price":"$2.17430","currency":"USD"},{"qty":250,"price":"$2.04156","currency":"USD"},{"qty":500,"price":"$1.78636","currency":"USD"},{"qty":1000,"price":"$1.48013","currency":"USD"},{"qty":2500,"price":"$1.44450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fabd99344b3a1a4932c1dc9f6eeebd36.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does SN74S38NS require a pull-up resistor?","answer":"Yes.
