The MC74VHC4053MELG is a multiplexer switch IC manufactured by onsemi, featuring three independent single-pole double-throw (SPDT) analog switches. It operates within a supply voltage range of 2 V to 6 V for both single and dual power configurations. The device provides a maximum on-resistance of 100 Ohms with a channel-to-channel matching of 10 Ohms. Key electrical parameters include a -3dB bandwidth of 120 MHz, a propagation delay of 40 ns, and an off-time of 160 ns. It supports an operating temperature range from -55°C to +125°C and is housed in a 16-SOEIAJ surface-mount package.
This component is officially classified as obsolete and no longer manufactured by onsemi. Sourcing new original parts is not possible through standard distribution channels. Verification should focus on identifying qualified replacement components or evaluating existing stock from secondary market suppliers, ensuring compatibility with the required 16-SOEIAJ package and electrical specifications.
Designers requiring this specific part number must account for its end-of-life status. Selection should prioritize direct replacements that match the 100 Ohm on-resistance, 120 MHz bandwidth, and 16-pin SOIC/SOEIAJ footprint. Verify that alternative candidates support the same 2 V to 6 V supply range and -55°C to +125°C industrial temperature grade to maintain system performance without redesign.
The MC74VHC4053MELG belongs to the 74VHC4053 family of high-speed CMOS analog switches. This series is designed for low-voltage digital and analog applications, offering improved speed over standard HC logic families while maintaining compatibility with 5 V and 3.3 V systems. The ELG suffix typically denotes specific packaging and environmental compliance attributes defined by the manufacturer.
Publicly confirmed substitute part numbers include SN74LV4053ANSR from Texas Instruments and CD4053BM from Texas Instruments. These alternatives provide similar multiplexer functionality but may differ in specific electrical characteristics such as on-resistance or supply voltage ranges. Verify pinout compatibility and thermal performance before implementation.
