The MM74HC4052WMX is a dual 4-channel analog multiplexer implemented in advanced silicon-gate CMOS technology. It features bidirectional switching, low on-resistance, and linearization circuitry for improved linearity. The device supports analog signal ranges up to ±6V with digital control signals from 0 to 6V. It includes an inhibit control pin to disable all switches simultaneously. The component operates within a supply voltage range of 2V to 6V for VCC and 0V to -6V for VEE. It is housed in a 16-lead SOIC package (M16B) and is available in tape and reel packaging.
Verify the manufacturer designation, as the datasheet originates from Fairchild Semiconductor. Confirm that the 'X' suffix corresponds to tape and reel packaging as specified in the ordering code section. Ensure the M16B package number matches the wide SOIC physical dimensions required for the design.
Select this component for applications requiring dual independent 4-channel analog switching. Verify that the supply voltage configuration (VCC and VEE) aligns with the required analog signal swing. Check that the maximum quiescent current and leakage specifications meet the power budget constraints of the target system.
This part belongs to the MM74HC405x family, which also includes the MM74HC4051 (8-channel) and MM74HC4053 (triple 2-channel). All devices share similar CMOS technology and electrical characteristics but differ in channel count and configuration. The MM74HC4052 specifically provides two sets of 4-switch multiplexing.
Public confirmed substitute part numbers are not provided in the source material.
