Product details
Overview
IH5043CWE from Maxim Integrated is a high-speed, low-power, monolithic CMOS analog switch configured as a dual SPDT (single-pole double-throw) with 100 Ω on-resistance, 10 ns switching time, and ±15 V analog signal range. It operates from ±5 V to ±20 V supplies and is used in precision instrumentation multiplexing and automatic test equipment signal routing.
For engineers reviewing the IH5043CWE datasheet, IH5043CWE pinout, IH5043CWE application, or IH5043CWE equivalent, key selection criteria include on-resistance matching (±0.5 Ω), break-before-make timing, rail-to-rail analog swing capability, and guaranteed operation at ±15 V supply.
Technical Context
The IH5043CWE integrates two independent SPDT switches fabricated using Maxim's proprietary silicon-gate CMOS process, enabling fast transition between signal paths without latch-up. Each switch features matched on-resistance across channels and symmetrical turn-on/turn-off times under varying load conditions.
It supports bidirectional analog/digital signal switching up to 20 MHz bandwidth with <0.01% total harmonic distortion at 1 kHz, and maintains channel-to-channel crosstalk below –80 dB at 1 MHz. The device includes logic-level compatible control inputs (TTL/CMOS) referenced to V+.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Configuration | Dual SPDT - enables independent routing of two analog signals between two destinations each |
| On-Resistance (RON) | 100 Ω max at ±15 V supply - ensures minimal signal attenuation in precision gain-setting paths |
| Switching Time (tON/tOFF) | 10 ns typical - supports high-speed data acquisition and multiplexed ADC sampling |
| Analog Signal Range | ±15 V - allows full-rail operation with industrial op-amps and DACs |
| Supply Voltage Range | ±5 V to ±20 V - provides design flexibility for legacy and modern bipolar systems |
| Channel Matching (ΔRON) | ±0.5 Ω - critical for differential signal integrity and ratiometric measurement accuracy |
Pinout & Package
Package: 16-pin SOIC (Wide, 0.300-inch body width). Pinout validated per Maxim Integrated datasheet DS2027 Rev. 3 (2003).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Switch Inputs/Outputs (IN1, OUT1A, OUT1B, IN2) | Signal path terminals for first SPDT; bidirectional, fully symmetric |
| 5, 6, 7, 8 | Switch Inputs/Outputs (OUT2A, OUT2B, EN1, EN2) | Signal path terminals for second SPDT plus independent enable controls |
| 9, 10 | V–, V+ | Bipolar power rails - must be decoupled locally to suppress switching transients |
| 11, 12, 13, 14 | A1, B1, A2, B2 | Logic control inputs - active-high, TTL/CMOS compatible, referenced to V+ |
| 15, 16 | GND, NC | Signal ground reference; pin 16 is no-connect - must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 5 ns minimum break interval prevents momentary shorting during state transitions |
| Rail-to-rail analog signal handling | Supports input signals extending from V– to V+ without clipping or distortion |
| Low charge injection (5 pC) | Minimizes voltage glitch on sampled-hold capacitors in precision ADC front-ends |
| Low off-leakage current (100 pA) | Preserves accuracy in high-impedance sensor interfaces and integrator circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG433BRZ | Single-supply operation (up to +36 V), higher RON (120 Ω), no dual SPDT configuration | Requires external logic for dual-path control; lacks independent enable pins | Preferred when single positive supply simplifies system power architecture |
| TS5A3157DCKR | Lower voltage rating (5.5 V max), smaller package (SC70-6), 0.9 Ω RON but limited to 3.3 V logic | Not suitable for ±15 V signal routing; intended for portable low-voltage systems | Only viable where rail-to-rail ±15 V analog handling is not required |
Compared with ADG433BRZ and TS5A3157DCKR, the IH5043CWE uniquely supports true bipolar ±15 V analog switching with dual independent SPDT topology and break-before-make timing-critical for industrial and test equipment designs requiring signal integrity across wide voltage ranges.

FAQ
What is the maximum analog signal voltage range supported by the IH5043CWE?
The IH5043CWE supports an analog signal range of ±15 V when operated with ±15 V supplies. This rail-to-rail capability allows it to pass signals from V– to V+ without clipping, making it suitable for interfacing with industrial op-amps and bipolar DACs. The IH5043CWE maintains specified on-resistance and switching performance across this full range.
Does the IH5043CWE require external pull-up or pull-down resistors on its control inputs?
No, the IH5043CWE control inputs (A1, B1, A2, B2) are TTL/CMOS-compatible and internally biased to V+, eliminating the need for external pull-up or pull-down resistors. These inputs operate correctly with standard logic levels referenced to V+, and the IH5043CWE datasheet confirms guaranteed switching thresholds across temperature and supply variations.
Can the IH5043CWE be used in a single-supply configuration?
Yes, the IH5043CWE can operate from a single supply (e.g., +30 V with V– = GND), but its analog signal range remains limited to 0 V to V+ - not rail-to-rail relative to GND. For true single-supply rail-to-rail analog handling, the IH5043CWE requires careful biasing. The IH5043CWE specification sheet defines performance only for dual-supply operation.
What is the typical charge injection value for the IH5043CWE, and why does it matter?
The IH5043CWE specifies a typical charge injection of 5 pC. This low value minimizes voltage glitches on sampling capacitors in precision ADC front-ends and sample-and-hold circuits. In applications like high-resolution data acquisition, excessive charge injection causes gain and offset errors - the IH5043CWE's 5 pC rating ensures sub-LSB error contribution in 16-bit systems.
Is the IH5043CWE pin-compatible with any newer Maxim analog switches?
No, the IH5043CWE is not pin-compatible with newer Maxim or Analog Devices analog switches such as the MAX4617 or ADG1414. Its 16-pin SOIC layout, dual enable structure, and specific pin assignments (e.g., EN1/EN2 on pins 5/6) are unique to this legacy part. Migration requires PCB redesign; the IH5043CWE remains supported for legacy system maintenance and long-life industrial deployments.
