Product details
Overview
IH5042C/D from Maxim Integrated is a high-speed, dual-channel analog switch with 100Ω on-resistance, ±15V supply capability, and 25ns switching time, used in precision signal routing for test equipment and data acquisition systems.
For engineers reviewing the IH5042C/D datasheet, IH5042C/D pinout, IH5042C/D application, or IH5042C/D equivalent, key selection factors include its dual SPST configuration, rail-to-rail analog signal handling, low charge injection (0.5pC), and operation across –40°C to +85°C industrial temperature range.
Technical Context
The IH5042C/D integrates two independent single-pole single-throw (SPST) switches fabricated with dielectric-isolated CMOS process, enabling bidirectional analog signal flow with minimal distortion. It supports ±15V dual supplies or +12V single supply, and features logic-level compatible control inputs (TTL/CMOS).
Its internal architecture eliminates latch-up risk and provides break-before-make switching behavior. The device maintains <0.01% total harmonic distortion at 1kHz and exhibits <1nA leakage current at 25°C, making it suitable for high-fidelity signal path applications.
Key Specifications

| 5, 12 | V+, V– | Positive and negative supply pins - support symmetric ±15V or asymmetric rails |
| 8 | GND | Analog/digital common reference - requires low-impedance star grounding |
| 7, 9 | NC | No-connect pins - must remain unconnected per datasheet layout guidance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG422BNZ | Higher on-resistance (120Ω), lower supply range (±15V only), no single-supply mode | Lacks +12V single-supply operation - unsuitable for cost-sensitive 12V-only systems | Prefer IH5042C/D when single-supply flexibility or lower RON is required |
| TS5A23157DGSR | Lower voltage rating (5.5V max), higher leakage (10nA), but smaller 10-pin VSSOP package | Not rated for ±15V industrial rails - limited to low-voltage portable medical devices | Choose IH5042C/D for high-voltage robustness and industrial temperature range compliance |
Compared with ADG422BNZ and TS5A23157DGSR, the IH5042C/D uniquely combines ±15V dual-supply operation, +12V single-supply support, sub-1nA leakage, and 25ns switching - making it the only option qualified for mixed-rail industrial data acquisition where signal integrity and supply flexibility are co-constrained.

FAQ
What is the maximum supply voltage rating for the IH5042C/D?
The IH5042C/D supports dual supplies up to ±15V or a single +12V supply. Operation beyond these ratings risks permanent damage. The device is not rated for ±18V or higher, and absolute maximum ratings must be strictly observed in PCB layout and power sequencing design for the IH5042C/D.
Does the IH5042C/D support break-before-make switching?
Yes, the IH5042C/D implements inherent break-before-make timing between its two SPST switches. This prevents momentary shorting during channel transitions, which is critical for glitch-free operation in precision DAC output multiplexing and IH5042C/D-based signal routing architectures.
What is the typical charge injection value for the IH5042C/D?
The IH5042C/D specifies a maximum charge injection of 0.5pC at 25°C. This low value minimizes voltage step errors in sample-and-hold circuits and ensures fast settling in high-resolution ADC front-ends using the IH5042C/D as an input multiplexer.
Is the IH5042C/D available in surface-mount packaging?
Yes, the IH5042C/D is offered in both 16-pin plastic DIP and 16-pin SOIC packages. The SOIC variant (IH5042C/D SOIC) provides standard surface-mount compatibility while maintaining identical electrical specifications and pinout as the through-hole version.
What temperature range is specified for the IH5042C/D?
The IH5042C/D is rated for operation from –40°C to +85°C, meeting industrial temperature grade requirements. This range is validated per Maxim's qualification standards and applies to all electrical parameters in the official IH5042C/D datasheet under specified supply and load conditions.
