TC74HC21AF(EL,F) is listed in the Inverter Gates range at ChipApex. The manufacturer field lists Toshiba Semiconductor and Storage. Its product description is IC GATE AND 2CH 4-INP 14SOIC. Review the specifications below when checking this part for your BOM.
The TC74HC21AF(EL,F) is a dual 4-input AND gate integrated circuit belonging to the HC/UH logic series. It utilizes CMOS technology and is housed in a 14-pin Plastic Dual Small Outline (PDSO14) package, also identified as SOIC-14. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports an operating temperature range from -40 °C to +85 °C. Key electrical characteristics include a load capacitance of 50 pF and a maximum propagation delay typical of the HC series.
Verify the specific ordering suffix (EL,F) against the manufacturer's current datasheet to confirm tape-and-reel packaging specifications. Ensure compliance with RoHS directives if required by your application, noting that some legacy listings may indicate non-compliance. Confirm pinout compatibility with existing PCB footprints before procurement.
Select this component when a compact solution for dual 4-input AND functionality is required in space-constrained designs. The HC series offers a balance of speed and power efficiency suitable for general digital applications. Consider the SOIC-14 package dimensions for board layout constraints and ensure the operating voltage range aligns with the system's power supply rails.
Toshiba Semiconductor and Storage manufactures this part as part of its broad portfolio of general-purpose logic ICs. The TC74HC21AF(EL,F) falls under the HC/UH series, designed for high-speed CMOS operations. Toshiba provides these components for use in consumer, industrial, and automotive electronics, leveraging their expertise in semiconductor manufacturing to deliver reliable logic solutions.
Equivalent parts from other manufacturers include the SN74HC21N or MC74HC21ADJR2G. Verify pin compatibility and electrical parameters such as propagation delay and output drive current before substitution. Ensure the replacement package matches the SOIC-14 form factor.
