The MM74HC4052MX is a dual 4-channel analog multiplexer/demultiplexer manufactured by onsemi using advanced silicon-gate CMOS technology. It operates within a supply voltage range of 2 V to 6 V for VCC and 0 V to -6 V for VEE, supporting bidirectional signal transmission. The device features low on-resistance (typical 30 Ω at VCC-VEE = 9V) and low off-leakage currents. It includes an inhibit control that disables all switches when HIGH. The component is housed in a 16-lead Small Outline Integrated Circuit (SOIC) package with JEDEC MS-012 narrow body specifications.
Verify the manufacturer origin carefully as this part number was originally from Fairchild Semiconductor and may now be produced under onsemi branding. Confirm the specific package variant matches the required board layout. Check current lifecycle status as older CMOS components may have limited availability or obsolescence risks.
Select this component when a dual 4-channel configuration is required rather than single 8-channel or triple 2-channel alternatives. Ensure the application supports the specified ±6V analog input range relative to the supply rails. Consider the SOIC-Narrow package dimensions during PCB footprint design.
This device belongs to the MM74HC405x family, which also includes the MM74HC4051 (8-channel) and MM74HC4053 (triple 2-channel). All three share similar electrical characteristics and pinout structures but differ in channel count and internal switching topology.
