74LS12N is listed in the Inverter Gates range at ChipApex. The manufacturer field lists Rochester Electronics, LLC. Its product description is IC GATE NAND 3CH 3-INP 14DIP. Review the specifications below when checking this part for your BOM.
The SN74LS12N is a NAND gate integrated circuit manufactured by Rochester Electronics, LLC. It belongs to the LS (Low-power Schottky) series and operates within the TTL logic family. The device contains three independent 3-input NAND gates housed in a 14-pin Plastic Dual In-line Package (PDIP). Key electrical characteristics include open-collector outputs, which facilitate wired-AND connections and voltage level shifting. The component is designed for standard digital logic applications requiring reliable switching performance.
Verify the manufacturer marking matches Rochester Electronics, LLC, as this part is often sourced from authorized distributors of surplus or obsolete inventory. Confirm the package type is PDIP-14 and check for leaded solder finish specifications if RoHS compliance is not required. Ensure the datasheet version aligns with the specific lot date code to guarantee parameter consistency during integration.
Select this component when designing circuits that require multiple independent NAND gates with open-collector outputs in a compact DIP package. The LS series offers a balance of speed and power dissipation suitable for general-purpose digital designs. Consider the open-collector nature for applications needing pull-up resistors or driving loads at voltages higher than the logic supply.
This component is part of the broader 74xx series of logic ICs, specifically the LS variant known for improved power-speed product compared to standard TTL. Rochester Electronics specializes in maintaining supply chains for legacy and discontinued semiconductor parts, ensuring availability for long-life industrial and aerospace applications where original OEM sources may no longer produce these devices.
Direct pin-compatible replacements include other manufacturers' SN74LS12N equivalents such as those from Texas Instruments, National Semiconductor, or Motorola. Ensure any substitute maintains the same LS series electrical characteristics and open-collector output configuration to preserve circuit functionality without modification.
