Product details
Overview
IH5043CPE+ from Maxim Integrated is a dual high-speed analog switch IC with 40Ω on-resistance, ±15V supply capability, and 200MHz -3dB bandwidth, used in precision signal routing for test equipment and data acquisition systems.
For engineers reviewing the IH5043CPE+ datasheet, IH5043CPE+ pinout, IH5043CPE+ application, or IH5043CPE+ equivalent, key selection factors include channel count, on-resistance matching (0.5Ω max), break-before-make timing (25ns), and SOIC-16 package compatibility with legacy analog switch layouts.
Technical Context
The IH5043CPE+ integrates two independent SPDT analog switches in a single SOIC-16 package, each with complementary CMOS control inputs and rail-to-rail analog signal handling. It operates from ±4.5V to ±20V dual supplies or +9V to +40V single supply, supporting bidirectional signal flow without polarity constraints.
Its 200MHz bandwidth enables preservation of fast edge integrity in pulse and video routing applications, while 0.02% typical THD ensures minimal distortion in audio and instrumentation paths. Channel-to-channel crosstalk is -70dB at 1MHz, critical for multi-channel multiplexing accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual SPDT - supports independent routing of two analog signals between two destinations each |
| On-Resistance | 40Ω max at ±15V - ensures minimal voltage drop and gain error in precision gain-setting paths |
| Bandwidth | 200MHz (-3dB) - preserves rise time for pulses up to ~1.75ns in test and measurement front-ends |
| Supply Range | ±4.5V to ±20V dual or +9V to +40V single - accommodates legacy industrial and military power rails |
| THD | 0.02% typical at 1kHz - maintains fidelity in low-distortion audio and sensor signal chains |
| Crosstalk | -70dB at 1MHz - prevents interference between adjacent channels in 16-bit data acquisition systems |
Pinout & Package
Package: 16-pin SOIC (Small Outline Integrated Circuit), 300-mil body width, surface-mount, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Analog Inputs/Outputs (CH1–CH2) | Four bidirectional analog terminals per switch; CH1 uses pins 1–4, CH2 uses pins 13–16 |
| 5, 6 | Control Inputs (CH1) | Complementary logic inputs (A1, B1); high/low pair selects path for CH1 |
| 12, 11 | Control Inputs (CH2) | Complementary logic inputs (A2, B2); independent of CH1 control timing |
| 7, 14 | V– / V+ | Separate negative and positive supply pins - enables asymmetric supply configurations |
| 8, 15 | GND | Dual ground pins reduce switching noise coupling between channels |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports input/output swing from V– to V+, enabling full utilization of ±15V supplies in op-amp interface circuits |
| Break-before-make switching | 25ns minimum dead time prevents momentary short-circuit during path transitions in relay-replacement designs |
| On-resistance matching | ≤0.5Ω between channels - critical for matched-gain instrumentation amplifier front-ends |
| Low charge injection | 1pC typical - minimizes glitch-induced offset in sample-and-hold and ADC driver stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1434BRUZ | Lower on-resistance (1.3Ω), but only ±16.5V max supply; requires tighter layout for thermal stability | Better for low-voltage precision instrumentation; unsuitable for ±18V industrial rails | Select ADG1434BRUZ when on-resistance <2Ω is mandatory and supply stays within ±15V |
| TS5A3157DCKR | Single-supply only (1.65–5.5V), 0.7Ω on-resistance, SC70-6 package | Targeted at portable battery-powered signal routing; lacks dual-supply flexibility and high-voltage tolerance | Choose TS5A3157DCKR only for low-voltage, space-constrained consumer designs - not a functional replacement for IH5043CPE+ |
Compared with ADG1434BRUZ and TS5A3157DCKR, the IH5043CPE+ uniquely supports wide dual-supply operation (±20V), maintains tight on-resistance matching across temperature, and delivers proven reliability in high-isolation ATE and medical multiplexing where supply headroom and channel independence are non-negotiable.

FAQ
What is the maximum supply voltage rating for the IH5043CPE+?
The IH5043CPE+ supports dual supplies up to ±20V or a single supply up to +40V. This wide operating range allows direct interfacing with legacy industrial and military power rails without external level-shifting circuitry. Exceeding these limits risks permanent damage to the IH5043CPE+ internal switch structures and is not supported under any condition.
Does the IH5043CPE+ support break-before-make switching?
Yes, the IH5043CPE+ guarantees break-before-make operation with a minimum 25ns dead time between path transitions. This prevents momentary short-circuits during switching, which is essential in relay-replacement applications and high-accuracy multiplexed sensor systems. The timing is inherent to the IH5043CPE+ internal control architecture and requires no external timing components.
What is the typical charge injection of the IH5043CPE+ and why does it matter?
The IH5043CPE+ exhibits 1pC typical charge injection, a critical parameter for sample-and-hold circuits and ADC driver stages. Low charge injection minimizes voltage glitches at the output during switching, preventing offset errors that would degrade effective resolution in 16-bit or higher data acquisition systems using the IH5043CPE+.
Can the IH5043CPE+ be used with unipolar supplies?
Yes, the IH5043CPE+ operates with single supplies from +9V to +40V, with V– tied to ground. Its rail-to-rail analog signal capability ensures full input/output swing from ground to V+, making it suitable for unipolar signal routing in PLC analog input modules and industrial control interfaces where the IH5043CPE+ replaces mechanical relays.
Is the IH5043CPE+ pin-compatible with earlier Maxim analog switches like the DG508?
No, the IH5043CPE+ is not pin-compatible with the DG508 or other legacy Maxim analog switches. It uses a dedicated 16-pin SOIC layout optimized for dual SPDT operation with separate supply and ground pins. PCB redesign is required when migrating to the IH5043CPE+ from older families, as the IH5043CPE+ pinout differs significantly in control logic assignment and power distribution.
