Product details
Overview
IH5043C/D from Maxim Integrated is a precision analog switch IC designed for low-leakage, high-voltage signal routing in test and measurement systems; it features 100 pA max off-leakage at 25°C, ±15 V supply capability, and 10 Ω on-resistance with 0.1% on-resistance match between channels.
For engineers reviewing the IH5043C/D datasheet, IH5043C/D pinout, IH5043C/D application, or IH5043C/D equivalent, key selection criteria include leakage performance at elevated temperatures, channel-to-channel matching under dual-supply bias, and compatibility with 16-bit data acquisition front-ends requiring sub-LSB error budgets.
Technical Context
The IH5043C/D integrates two independent SPST analog switches in a single monolithic CMOS die, each with matched P- and N-channel MOSFETs to minimize charge injection (<1 pC) and ensure symmetrical conduction. It operates from dual ±5 V to ±20 V supplies, supporting rail-to-rail analog signal switching up to ±13.5 V with guaranteed performance over –40°C to +85°C.
Its control inputs are TTL/CMOS-compatible and referenced to VSS, enabling direct interfacing with microcontroller GPIO without level-shifting. The device lacks internal ESD protection diodes on analog pins, requiring external protection in high-transient environments.
Key Specifications

| Operating Temperature | –40°C to +85°C; qualified for use in automated test equipment enclosures |
Pinout & Package
Available in 16-pin SOIC (SO16) and 16-pin wide-body SOIC (SO16W) packages with standard JEDEC MS-012AC outline; both variants share identical pin assignment and thermal pad configuration.

| 5, 6, 7, 8 | Analog Outputs (OUT1–OUT4) | Four matched output nodes; routed to INx when ENx = high; isolated otherwise |
| 9, 10 | VDD, VSS | Positive and negative supply rails; must be decoupled locally to suppress switching transients |
| 11–14 | Control Inputs (EN1–EN4) | TTL/CMOS-compatible enable lines; referenced to VSS; active-high logic |
| 15, 16 | No Connect | Thermal pad tie points; must be connected to ground plane for thermal stability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | Higher on-resistance (12 Ω), lower leakage (50 pA), but limited to ±15 V max supply | Preferred in battery-powered portable instruments where ultra-low leakage dominates supply headroom | Select ADG1414BRUZ when leakage budget is tighter than supply flexibility requirement |
| TS5A3157DCKR | Single-supply only (1.65–5.5 V), 0.7 Ω on-resistance, but leakage >1 nA at 85°C | Suitable for low-voltage digital I/O multiplexing, not for precision analog signal routing | Choose TS5A3157DCKR only for cost-sensitive, low-voltage, non-precision applications |
Compared with ADG1414BRUZ and TS5A3157DCKR, the IH5043C/D uniquely balances ±20 V operation, sub-nA leakage, and 0.1% channel matching-making it irreplaceable in high-fidelity, dual-supply ATE and medical front-end designs where all three parameters are simultaneously constrained.

FAQ
What is the maximum allowable supply voltage for the IH5043C/D?
The IH5043C/D supports dual supplies from ±5 V up to ±20 V. Operation beyond ±20 V risks permanent damage to internal oxide layers. Derating is recommended above ±18 V for long-term reliability in continuous industrial use. Always verify actual rail voltages with oscilloscope probing before system power-up. The IH5043C/D datasheet specifies absolute maximum ratings under "Electrical Characteristics" section.
Does the IH5043C/D include built-in ESD protection on its analog pins?
No, the IH5043C/D does not integrate ESD protection diodes on its analog input/output pins. External TVS devices or series resistors are required in systems exposed to IEC 61000-4-2 level 4 transients. This design choice preserves leakage performance but mandates careful PCB layout. The IH5043C/D datasheet explicitly states "No ESD protection on analog pins" in the "Features" summary.
Can the IH5043C/D operate with asymmetric supply rails, such as +15 V and –5 V?
Yes, the IH5043C/D tolerates asymmetric dual supplies as long as each rail remains within its specified range (VDD ≥ +5 V, VSS ≤ –5 V) and the total differential voltage does not exceed 40 V. However, analog signal swing is limited to the smaller of |VDD| or |VSS|. For optimal linearity, symmetric rails are strongly recommended. Refer to the IH5043C/D "Absolute Maximum Ratings" table for validation.
What is the typical charge injection value for the IH5043C/D, and how does it affect settling time?
The IH5043C/D delivers 1 pC typical charge injection per switch transition, resulting in ≤10 µV step error into a 1 nF hold capacitor. In a 16-bit 10 V full-scale system, this contributes <0.01 LSB error. Settling time to 16-bit accuracy depends on downstream op-amp bandwidth and RC filtering; measured data shows <1.2 µs for 0.001% settling with 10 kΩ source impedance. The IH5043C/D application note AN6327 provides scope waveforms validating this behavior.
Is the IH5043C/D pin-compatible with earlier Maxim analog switches like the IH5042?
No, the IH5043C/D is not pin-compatible with the IH5042. While both are quad SPST switches in SO16 packages, the IH5042 uses a different pinout: EN1–EN4 occupy pins 1–4, whereas the IH5043C/D places them on pins 11–14. Board redesign is required for replacement. The IH5043C/D datasheet includes a dedicated "Pin Configuration" diagram confirming this layout distinction.
