MAX4634EUB+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4634EUB+T is a fast, low-voltage, 4-channel CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +5.5V supply and features a maximum on-resistance (RON) of 4Ω at +25°C with a +5V supply. The device guarantees RON matching between channels to 0.3Ω and RON flatness of 1Ω over the specified signal range. Off-leakage current is limited to 0.1nA (max) at +25°C. Switching times include a turn-on time (tON) of 18ns and a turn-off time (tOFF) of 11ns at +25°C. It is housed in a 10-pin μMAX package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix matches the required package type, as the MAX4634 family includes both μMAX and TDFN variants. Confirm RoHS compliance status indicated by the '+' suffix. Ensure the specific temperature grade corresponds to the design requirements. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring a single-supply analog switch with low on-resistance and fast switching characteristics. Consider the 10-pin μMAX package for space-constrained surface-mount applications. Evaluate the +1.8V to +5.5V supply range against system power constraints. Verify that the 4-channel configuration meets the multiplexing needs without requiring additional components.
