Product details
Overview
IH5042CPE from Maxim Integrated is a dual high-speed analog switch configured as two independent SPST switches, with 100 Ω on-resistance, 25 ns turn-on time, and ±15 V analog signal handling capability; used in precision test equipment for signal routing between DUT and measurement instruments.
For engineers reviewing the IH5042CPE datasheet, IH5042CPE pinout, IH5042CPE application, or IH5042CPE equivalent, key selection factors include on-resistance matching, break-before-make timing, supply voltage range, and leakage current at elevated temperatures.
Technical Context
The IH5042CPE integrates two matched CMOS transmission gates in a single 16-pin PDIP package, supporting dual-channel bidirectional analog switching with TTL/CMOS-compatible control inputs. It operates from dual ±15 V supplies and maintains <0.5 Ω on-resistance match between channels over temperature.
Its break-before-make architecture prevents momentary shorting during channel switching, and it specifies 1 nA maximum off-leakage at +25°C with <10 pF off-capacitance per switch - critical for low-distortion AC coupling in automated test systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual SPST, break-before-make, bidirectional analog |
| On-Resistance | 100 Ω max at ±15 V supplies - ensures minimal signal attenuation in 50 Ω–1 kΩ impedance paths |
| Turn-On Time | 25 ns max - supports switching rates up to 10 MHz in multiplexed data acquisition |
| Off-Leakage Current | 1 nA max at +25°C - preserves DC accuracy in high-impedance sensor front-ends |
| Analog Voltage Range | ±15 V - enables full-rail switching of industrial process signals and audio waveforms |
| Control Logic | TTL/CMOS compatible - interfaces directly with FPGA I/O or microcontroller GPIO without level shifting |
Pinout & Package
16-pin plastic dual in-line package (PDIP), 0.3-inch body width, through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Channel 1 Input/Output | Bidirectional analog path - no polarity restriction; connects to DUT or instrument |
| 3 | Channel 1 Control | Active-high TTL/CMOS input - enables switch when ≥2.0 V |
| 4, 5 | Channel 2 Input/Output | Independent second analog path - electrically isolated from Channel 1 |
| 6 | Channel 2 Control | Separate enable for Channel 2 - allows asynchronous routing control |
| 7 | GND | Analog ground reference - must be star-connected to minimize crosstalk |
| 8 | V− | Negative supply rail - required for ±15 V operation; not tied to GND |
| 9 | V+ | Positive supply rail - supplies internal charge pump and gate drive |
| 10–16 | No Connect / Reserved | Internally unused - must remain unconnected per datasheet |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| ADG1421BRZ | Lower on-resistance (0.6 Ω), but requires single +15 V supply only - no negative rail needed | Not suitable for true bipolar ±15 V signal routing; limited to unipolar or ground-referenced paths | Select ADG1421BRZ only if system uses single-supply architecture and does not require full-rail bipolar switching |
| TS5A3157DCKR | Single-channel, 0.7 Ω on-resistance, 3.3 V logic compatible - lacks dual-channel integration and ±15 V rating | Requires two devices and external level-shifting for dual-channel ±15 V use - increases board area and BOM count | Choose TS5A3157DCKR only for low-voltage, space-constrained designs where bipolar operation is unnecessary |
Compared with ADG1421BRZ and TS5A3157DCKR, the IH5042CPE uniquely supports true dual-channel, ±15 V analog switching in a single PDIP package - essential for legacy test systems requiring rail-to-rail bipolar signal routing without supply redesign.

FAQ
What is the maximum analog signal voltage range supported by the IH5042CPE?
The IH5042CPE supports analog signals from −15 V to +15 V when operated with dual ±15 V supplies. This full-rail capability allows it to pass undistorted industrial process signals, audio waveforms, and calibration references without clipping or distortion - a key requirement in precision test equipment using the IH5042CPE.
Does the IH5042CPE require external level-shifting for TTL-compatible control inputs?
No, the IH5042CPE features TTL/CMOS-compatible control inputs that accept logic-high signals ≥2.0 V and logic-low signals ≤0.8 V directly - no external level shifters needed. This simplifies interface design with FPGAs, microcontrollers, and digital I/O cards commonly used alongside the IH5042CPE in automated test systems.
Is the IH5042CPE pin-compatible with other Maxim analog switches like the IH5041?
No, the IH5042CPE is not pin-compatible with the IH5041. The IH5041 is a quad SPST switch in a 20-pin package, while the IH5042CPE is a dual SPST device in a 16-pin PDIP. Their pinouts differ significantly - particularly in supply, ground, and control assignments - so PCB layout changes are required when substituting the IH5042CPE.
What is the typical on-resistance match between the two channels of the IH5042CPE?
The IH5042CPE guarantees ≤0.5 Ω on-resistance mismatch between its two channels across temperature and supply variations. This tight matching enables accurate ratiometric measurements and balanced signal routing - a critical performance attribute confirmed in the IH5042CPE datasheet and routinely leveraged in precision calibration subsystems.
Can the IH5042CPE operate from a single +15 V supply instead of dual ±15 V?
No, the IH5042CPE requires both V+ and V− supplies to function correctly; it cannot operate from a single +15 V rail. Its internal architecture depends on dual supplies to bias the transmission gates for true bipolar signal handling - attempting single-supply operation will result in undefined behavior or failure to switch, as specified in the IH5042CPE electrical characteristics table.
