Product details
Overview
IH5040CPE from Maxim Integrated is a monolithic 4-channel analog multiplexer/demultiplexer IC with CMOS architecture, ±15V analog signal handling capability, on-resistance of 125 Ω (max), and channel-to-channel crosstalk of –60 dB at 1 MHz. It operates over –40°C to +85°C and is used in data acquisition systems requiring high-voltage analog switching.
For engineers reviewing the IH5040CPE datasheet, IH5040CPE pinout, IH5040CPE application, or IH5040CPE equivalent, key selection considerations include its dual-supply operation, low charge injection (10 pC), break-before-make switching, and compatibility with TTL/CMOS control logic.
Technical Context
The IH5040CPE integrates four independent SPST analog switches controlled by a common 2-bit binary address decoder. Each switch features matched on-resistance and guaranteed break-before-make timing to prevent signal shorting during channel transitions.
It uses standard CMOS fabrication with polysilicon-gate process, enabling rail-to-rail analog signal swing up to ±15 V and supporting bidirectional signal flow without polarity restrictions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ | 8-channel, single-supply (±15 V not supported); RON = 100 Ω; no break-before-make guarantee | Requires external level-shifting for bipolar signals; unsuitable for ±15 V rail-to-rail operation | Prefer IH5040CPE where dual-supply operation and guaranteed break-before-make are mandatory |
| MAX4617CPE+ | Quad SPST, single-supply only (12 V max); RON = 60 Ω; charge injection = 25 pC | Limited to unipolar signals; higher charge injection increases settling error in precision sampling | Choose IH5040CPE for industrial bipolar sensor interfaces demanding low glitch and wide supply range |
Compared with ADG408BRZ and MAX4617CPE+, the IH5040CPE uniquely delivers guaranteed break-before-make timing, ±15 V analog rail support, and 10 pC charge injection-critical for high-fidelity multiplexed data acquisition in harsh environments.

FAQ
What is the maximum analog signal voltage range supported by the IH5040CPE?
The IH5040CPE supports analog signals from –15 V to +15 V when operated with dual ±15 V supplies. This rail-to-rail capability allows direct interfacing with industrial sensors and legacy op-amp circuits without level-shifting. The IH5040CPE maintains specified on-resistance and crosstalk performance across this full range.
Does the IH5040CPE require separate logic and analog supply connections?
Yes, the IH5040CPE uses dedicated pins for logic supply (VDD/VSS) and analog supply (V+/V–). This separation prevents digital noise coupling into analog paths and enables independent optimization of each supply domain. The IH5040CPE functions correctly with 5 V logic and ±15 V analog rails simultaneously.
Is break-before-make timing guaranteed for the IH5040CPE?
Yes, the IH5040CPE guarantees a minimum 25 ns break-before-make interval during channel switching. This specification is tested and ensured across temperature and supply variations, preventing transient shorting between channels. The IH5040CPE's internal decoder architecture enforces this timing without external timing components.
Can the IH5040CPE be used with unipolar analog signals only?
Yes, the IH5040CPE supports unipolar operation (e.g., 0 V to +15 V) when V– is tied to ground, but its full design value emerges in bipolar applications. The IH5040CPE retains low crosstalk and matched on-resistance in both configurations, making it flexible for mixed-signal systems where signal polarity varies.
What is the typical charge injection value for the IH5040CPE, and why does it matter?
The IH5040CPE specifies a maximum charge injection of 10 pC per switch transition. This low value minimizes voltage glitches in sample-and-hold circuits and ADC input stages, directly improving effective resolution and reducing settling time. For precision applications, the IH5040CPE's 10 pC rating is a key differentiator versus alternatives with >20 pC.
