The MM74HC4052WM is a dual single-pole quad-throw analog switch implemented in advanced silicon-gate CMOS technology. It provides two independent 4-channel multiplexers within a 16-lead Small Outline Integrated Circuit (SOIC) package, specifically the JEDEC MS-013 wide variant. The device supports bidirectional signal transmission and features linearization circuitry to lower on-resistance and improve linearity. It allows control of analog signals up to ±6V peak using digital control signals ranging from 0 to 6V. Key electrical parameters include a maximum supply voltage of 6V for VCC and -6V for VEE, a typical on-resistance of 80Ω at 4.5V differential supply, and a maximum quiescent current of 80μA.
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate tape and reel packaging versus tube packaging. Ensure the procurement source provides valid traceability documentation for this discontinued legacy part number.
Select this component when a dual 4-channel analog switching solution is required within a standard SOIC footprint. Verify that the application operates within the specified ±6V analog input range and utilizes compatible 0-6V digital control levels. Consider the package width constraints of the M16B designation during PCB layout design.
This device belongs to the MM74HC405x family of analog multiplexers, which also includes the single 8-channel MM74HC4051 and the triple 2-channel MM74HC4053. All three devices share similar CMOS construction and electrical characteristics but differ in channel count and internal switch topology. The MM74HC4052 specifically addresses designs requiring two separate 4:1 switching paths.
Public confirmed substitute part numbers include 74HC4052BQ manufactured by NXP Semiconductors.
