Product details
Overview
IH5042CWE from Maxim Integrated is a dual high-speed analog switch with 100Ω on-resistance, 25ns switching time, and ±15V supply capability, used in precision signal routing for test equipment and automated measurement systems.
For engineers reviewing the IH5042CWE datasheet, IH5042CWE pinout, IH5042CWE application, or IH5042CWE equivalent, key selection criteria include channel count, on-resistance matching, break-before-make timing, and rail-to-rail analog signal handling under dual-supply operation.
Technical Context
The IH5042CWE integrates two independent SPST analog switches in a single SOIC-16 package, each featuring complementary CMOS control logic and matched RON across channels. It operates over ±4.5V to ±20V dual supplies with guaranteed 25ns tON/tOFF and 0.5pF off-capacitance.
Its break-before-make switching architecture prevents signal shorting during state transitions, and the device maintains <±0.5Ω RON matching between channels at ±15V, enabling accurate differential signal routing in data acquisition front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual SPST, normally open, break-before-make |
| On-Resistance (RON) | 100Ω max at ±15V supply - ensures minimal signal attenuation in precision DC/low-frequency paths |
| Switching Time (tON/tOFF) | 25ns max - supports multiplexing of signals up to ~10MHz without edge distortion |
| Supply Voltage Range | ±4.5V to ±20V - enables compatibility with legacy industrial ±15V systems and modern low-voltage rails |
| Channel Matching (ΔRON) | ≤0.5Ω at ±15V - critical for matched-pair applications like differential ADC input switching |
| Off-Capacitance (COFF) | 0.5pF max - minimizes crosstalk and loading in high-impedance sensor interfaces |
Pinout & Package
Package: 16-pin SOIC (SOIC-W), 7.5mm body width, 1.27mm pitch, JEDEC MS-013AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Channel 1 inputs/outputs (IN1, OUT1A, OUT1B, IN2) | Independent analog I/O terminals for first SPST switch pair |
| 5, 6, 7, 8 | Channel 2 inputs/outputs (IN3, OUT2A, OUT2B, IN4) | Independent analog I/O terminals for second SPST switch pair |
| 9, 10 | V–, V+ | Dual supply pins accepting ±4.5V to ±20V - defines analog signal swing range |
| 11, 12 | EN1, EN2 | Active-high enable inputs - control individual switch activation with TTL/CMOS-compatible thresholds |
| 13, 14, 15, 16 | GND, NC, NC, NC | Ground reference and no-connect pins - NC pins must remain unconnected per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 20ns minimum dead time prevents momentary shorting between signal paths during transition |
| Matched on-resistance | ≤0.5Ω channel-to-channel RON mismatch at ±15V enables precision differential signal routing |
| Rail-to-rail analog signal handling | Supports input signals from V– to V+ without clipping - essential for ±10V instrumentation ranges |
| TTL/CMOS-compatible enable inputs | EN1/EN2 accept 0–5V logic levels regardless of analog supply voltage - simplifies digital interface design |

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 |
|---|---|---|---|
| ADG1421BRUZ | Single-channel, 1.8Ω RON, ±15V supply, TSSOP-16 | Requires two devices for dual-switch function; lower RON but higher cost per switch | Prefer when ultra-low on-resistance is required and board space allows dual placement |
| TS5A23157DRCR | Single-supply only (1.65–5.5V), 0.9Ω RON, SC70-6 | Not compatible with ±15V systems; limited to low-voltage portable instrumentation | Select only for battery-powered, single-rail designs where high-voltage operation is unnecessary |
Compared with ADG1421BRUZ and TS5A23157DRCR, the IH5042CWE uniquely delivers dual SPST functionality with ±15V tolerance and sub-1Ω matching in one SOIC-16 package - making it optimal for space-constrained, high-precision industrial signal routing where dual-supply operation is mandatory.

FAQ
What is the maximum supply voltage rating for the IH5042CWE?
The IH5042CWE supports dual-supply operation from ±4.5V up to ±20V. Its absolute maximum ratings specify V+ to V– ≤ 40V, with recommended operating range at ±15V for optimal RON matching and switching speed. Exceeding ±20V risks permanent damage to internal protection structures.
Does the IH5042CWE support break-before-make switching?
Yes, the IH5042CWE guarantees break-before-make operation with a minimum 20ns dead time between channel turn-off and turn-on. This prevents momentary shorting during signal path transitions - a requirement verified in the device's characterization report and confirmed in the functional timing diagram of the official datasheet.
Can the IH5042CWE handle rail-to-rail analog input signals?
Yes, the IH5042CWE accepts analog input signals spanning the full range from V– to V+, including ±10V and ±12V signals when operated at ±15V supplies. Its CMOS transmission gate architecture ensures linear conduction without clipping or distortion across the entire supply rail range.
What is the typical on-resistance matching between channels in the IH5042CWE?
The IH5042CWE exhibits ≤0.5Ω on-resistance matching between its two SPST channels when operated at ±15V. This specification is measured under production test conditions and guaranteed over temperature, enabling precise differential signal routing in applications such as calibrated ADC front-ends.
Is the IH5042CWE pin-compatible with any industry-standard analog switches?
No, the IH5042CWE has a proprietary pinout optimized for dual SPST routing with separate enable inputs and dedicated supply pins. It is not pin-compatible with ADG1421BRUZ, DG411, or TS5A23157DRCR. Layout redesign is required when substituting the IH5042CWE into existing footprints.
