The MC74LVX8051M is an analog multiplexer/demultiplexer manufactured by onsemi, utilizing silicon-gate CMOS technology. It features a single-pole, eight-position plus common off configuration housed in a SOEIAJ-16 package. The device operates with a power supply voltage range of 2.5 V to 6.0 V and supports analog voltages varying across the complete power supply range from VCC to GND. Key electrical parameters include a maximum ON resistance (Ron) of 40 Ohms at 3.0 V, propagation delays ranging from 1.0 ns to 8.0 ns depending on the signal path and voltage, and a bandwidth of 80 MHz. The component functions within a temperature range of -55°C to +85°C.
Verify the specific ordering suffix 'M' corresponds to the SOEIAJ-16 package type during procurement. Confirm RoHS compliance status if required, as Pb-Free variants exist under different suffixes such as 'MG'. Ensure that the selected packaging format matches the production requirements, noting that rail packaging is specified for this suffix. Cross-reference the manufacturer part number with official distributor catalogs to confirm current availability and lead times.
Select the MC74LVX8051M when an 8-channel analog switch is required with a wide analog signal range spanning the full supply voltage. This component is suitable for designs needing low crosstalk and high bandwidth up to 80 MHz. Consider the SOEIAJ-16 package constraints regarding board space and thermal dissipation. Verify that the control logic levels align with the system's digital interface, noting compatibility with both CMOS and LSTTL standards.
The MC74LVX8051 belongs to the LVX series of high-performance silicon-gate CMOS analog switches from onsemi. It serves as a functional equivalent to older metal-gate devices like the MC14051B while offering superior speed and linearity. The LVX family is designed for low-voltage applications, providing robust performance in portable and battery-operated electronics where power efficiency and signal integrity are critical.
The MC74LVX8051DR2G is a confirmed substitute part number offering identical functionality in a SOIC-16 package. Designers transitioning from other packages should verify pinout compatibility and ensure that the new package dimensions fit the existing footprint or modify the PCB layout accordingly.
