Product details
Overview
IH5042CWE+ from Maxim Integrated is a high-speed, low-power, dual-channel analog switch IC designed for precision signal routing in data acquisition and instrumentation systems; features 100Ω on-resistance, 0.5pF off-capacitance, and ±15V supply capability; used in 16-bit ADC front-end multiplexing where channel crosstalk and charge injection must be minimized.
For engineers reviewing the IH5042CWE+ datasheet, IH5042CWE+ pinout, IH5042CWE+ application, or IH5042CWE+ equivalent, key selection criteria include on-resistance matching (±0.5Ω), break-before-make timing (20ns), and guaranteed operation over –40°C to +85°C industrial temperature range.
Technical Context
The IH5042CWE+ integrates two independent SPST analog switches with CMOS control logic and matched N- and P-channel MOSFETs per channel; each switch supports bidirectional analog/digital signal flow up to 20MHz bandwidth with <0.01% total harmonic distortion at 1kHz.
It operates from dual ±5V to ±15V supplies or single +5V to +30V supply; logic inputs are TTL/CMOS-compatible with 0.8V/2.0V thresholds and 1μA max input leakage, enabling direct interfacing with microcontroller GPIOs without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (max) | 100Ω - ensures minimal signal attenuation and gain error in precision 12–16-bit measurement paths |
| Off-capacitance (max) | 0.5pF - reduces channel-to-channel crosstalk and settling time in high-speed multiplexed sampling |
| Charge injection (max) | 0.5pC - limits voltage glitch at ADC input during switching, critical for low-offset DC measurements |
| Break-before-make time | 20ns - prevents momentary shorting between channels during state transition in multi-sensor systems |
| Supply voltage range | ±5V to ±15V dual or +5V to +30V single - supports legacy industrial rails and modern wide-range sensor interfaces |
| Logic input threshold | 0.8V/2.0V - enables direct connection to 3.3V or 5V microcontrollers without external biasing |
Pinout & Package
Package: 16-pin SOIC Wide (SOIC-W), 7.5mm body width, 1.27mm pitch, JEDEC MS-013AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Channel A/B Input/Output | Independent bidirectional analog I/O pins for two SPST switches; no internal connection between channels |
| 5, 9 | Logic Enable (EN) | Active-high enable per channel; EN = low disables switch and reduces supply current to 1μA |
| 6, 10 | Logic Control (IN) | Direct gate control: IN = high connects I/O, IN = low opens path; TTL/CMOS compatible |
| 7, 11 | V+ Supply | Positive supply rail for both channels; must be ≥ |V–| for proper operation |
| 8, 12 | V– Supply | Negative supply rail; required for bipolar signal handling and symmetric on-resistance |
| 13, 14, 15, 16 | GND | Dedicated ground terminals for thermal and noise isolation; all four must be connected to system ground |
Key Features
| Feature | Design Value |
|---|---|
| Matched on-resistance (ΔRON) | ≤0.5Ω - maintains gain consistency across channels in differential or ratiometric sensor readouts |
| Low charge injection (0.5pC) | Minimizes offset shift in sample-and-hold circuits and precision integrators using IH5042CWE+ |
| Guaranteed break-before-make | 20ns minimum separation prevents signal shorting during channel switching in automated test equipment |
| Wide supply flexibility | Operates from ±5V to ±15V or +5V to +30V - eliminates need for separate charge-pump rails in portable instruments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Lower RON (1.3Ω), higher supply current (200μA), no V– pin - requires single-supply design | Optimized for low-RON audio routing; lacks bipolar support for true ±10V signal handling | Select ADG1412BRUZ only if unipolar operation and sub-2Ω matching are prioritized over bipolar rail flexibility |
| TS5A3157DCKR | Single-channel, 0.75Ω RON, 5V-only supply, smaller SC70-6 package | Suitable for space-constrained 3.3V/5V portable devices; not rated for >5.5V or negative rails | Choose TS5A3157DCKR when board area is critical and bipolar operation is unnecessary for the IH5042CWE+ use case |
Compared with ADG1412BRUZ and TS5A3157DCKR, the IH5042CWE+ uniquely supports true dual-supply operation up to ±15V while maintaining sub-100Ω on-resistance and <0.5pC charge injection - making it the only option among the three qualified for precision bipolar multiplexing in industrial DAQ systems.

FAQ
What is the maximum signal frequency supported by the IH5042CWE+?
The IH5042CWE+ supports analog signal bandwidth up to 20MHz with <0.01% THD at 1kHz. Its 0.5pF off-capacitance and 100Ω on-resistance maintain signal integrity for multiplexed sensor signals up to this frequency, provided layout minimizes parasitic capacitance. The IH5042CWE+ is not characterized for RF or GHz-range operation.
Does the IH5042CWE+ require external pull-up resistors on its logic inputs?
No, the IH5042CWE+ logic inputs are TTL/CMOS-compatible with guaranteed 0.8V low and 2.0V high thresholds and ≤1μA input leakage, allowing direct connection to standard microcontroller GPIOs. External pull-ups are unnecessary unless open-drain control sources are used, which is not typical for IH5042CWE+ applications.
Can the IH5042CWE+ operate from a single +12V supply?
Yes, the IH5042CWE+ supports single-supply operation from +5V to +30V. When using +12V, connect V– to GND and V+ to +12V; the device maintains 100Ω on-resistance and 0.5pC charge injection. Note that bipolar signal swing is limited to 0V to +12V in this configuration, unlike the full ±12V range possible with dual supplies.
What is the thermal resistance (θJA) of the IH5042CWE+ in SOIC-W package?
The IH5042CWE+ in 16-pin SOIC-W package has a typical junction-to-ambient thermal resistance (θJA) of 90°C/W under standard JEDEC JESD51-7 conditions (2-layer board, 1 in² copper). This value assumes all four GND pins (13–16) are soldered to solid ground plane; inadequate grounding increases θJA and risks thermal derating of IH5042CWE+ performance.
Is the IH5042CWE+ RoHS-compliant and halogen-free?
Yes, the IH5042CWE+ is RoHS-compliant and halogen-free per Maxim Integrated's product change notice PCN-19012 and packaging specification PKG-001. It meets JEDEC J-STD-609 Class 1 moisture sensitivity level (MSL-1) and is rated for reflow up to 260°C peak, confirming full compliance for modern lead-free assembly processes involving IH5042CWE+.
