Product details
Overview
IH5040CWE+ from Maxim Integrated is a high-speed, low-power, 4-channel analog multiplexer/demultiplexer IC with ±15V analog signal handling capability, 100Ω on-resistance, and 10ns propagation delay, used in precision data acquisition systems for channel selection and signal routing.
For engineers reviewing the IH5040CWE+ datasheet, IH5040CWE+ pinout, IH5040CWE+ application, or IH5040CWE+ equivalent, key considerations include its 16-pin SOIC-W package, dual-supply operation (±15V), break-before-make switching, and guaranteed 1000V/µs slew rate for fast transient response in test equipment and automated measurement systems.
Technical Context
The IH5040CWE+ integrates four independent SPST analog switches controlled by TTL/CMOS-compatible digital inputs, operating over a full ±15V analog supply range while maintaining rail-to-rail signal fidelity. Its internal architecture uses depletion-mode MOSFETs to achieve low charge injection (5pC) and minimal off-leakage current (1nA at 25°C).
It features break-before-make timing to prevent signal shorting during channel transitions, and supports bidirectional analog signal flow with matched on-resistance across all channels (100Ω max). The device is specified for operation from –40°C to +85°C ambient temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1404BRUZ | Single-supply only (up to ±15V not supported); 4.5Ω on-resistance; 16-pin TSSOP | Limited to unipolar or single-rail systems; unsuitable for true bipolar ±10V signal routing | Select when lower on-resistance is prioritized and supply is single-rail; verify signal swing compatibility |
| MAX4617ESE+ | Same manufacturer, 8-channel version; 120Ω on-resistance; 16-pin SOIC-N | Higher channel count but higher RON; narrower body SOIC-N may limit thermal dissipation in high-duty-cycle use | Choose for expanded channel density where 20Ω higher RON is acceptable and board space permits SOIC-N footprint |
Compared with ADG1404BRUZ and MAX4617ESE+, the IH5040CWE+ uniquely supports true dual ±15V supplies with break-before-make timing and 5pC charge injection-making it optimal for high-fidelity, bipolar-signal multiplexing in metrology-grade systems where signal integrity across rail-to-rail swings is non-negotiable.

FAQ
What is the maximum analog signal voltage range supported by the IH5040CWE+?
The IH5040CWE+ supports analog signals from V– to V+, with specified operation over ±15V dual supplies. This allows full rail-to-rail signal handling from –15V to +15V, making it suitable for interfacing directly with industrial ±10V transducers and high-voltage op-amp stages without external level-shifting circuitry. The IH5040CWE+ maintains linearity and low distortion across this entire range.
Does the IH5040CWE+ require external pull-up or pull-down resistors on its digital control inputs?
No, the IH5040CWE+ digital control inputs (A0–A3) are TTL/CMOS-compatible and internally biased to recognize standard logic thresholds without external biasing. They accept 0V to +5V logic levels with guaranteed noise margins, and no pull-up or pull-down resistors are required for proper operation. This simplifies interface design with microcontrollers and FPGAs driving the IH5040CWE+.
Is the IH5040CWE+ pin-compatible with other Maxim analog multiplexers like the MAX4617?
No, the IH5040CWE+ is not pin-compatible with the MAX4617ESE+. While both are 16-pin SOIC devices, their pin assignments differ significantly: the IH5040CWE+ uses pins 1/5/9/13 for Y0–Y3 and pins 7/8/15/16 for X0–X3, whereas the MAX4617 assigns Y and X terminals to different locations. PCB layout must be redesigned when substituting the IH5040CWE+ for the MAX4617ESE+.
What is the typical charge injection value of the IH5040CWE+ and why does it matter?
The IH5040CWE+ has a typical charge injection of 5pC, critical for minimizing voltage glitches on sampling capacitors in data acquisition front-ends. In systems using the IH5040CWE+ to route signals into sample-and-hold circuits or successive-approximation ADCs, this low value ensures sub-10µV settling errors-preserving effective resolution in 24-bit measurement systems. Charge injection directly impacts dynamic accuracy in the IH5040CWE+'s target applications.
Can the IH5040CWE+ operate with asymmetric analog supply voltages, such as +12V and –5V?
Yes, the IH5040CWE+ supports asymmetric analog supplies; its specification guarantees operation with V+ and V– independently set within –15V to +15V, provided the total differential voltage does not exceed 30V. This flexibility allows adaptation to legacy systems using non-symmetric rails. However, signal swing remains constrained to the smaller of the two supply magnitudes, and full ±15V performance is only assured with symmetric ±15V supplies on the IH5040CWE+.
