Product details
Overview
IH5043CPE from Maxim Integrated is a precision analog switch IC designed for bidirectional signal routing in low-distortion, low-leakage applications; features 4-channel SPST configuration, 100 Ω on-resistance (max), −100 dB crosstalk at 1 MHz, and ±15 V supply capability.
For engineers reviewing the IH5043CPE datasheet, IH5043CPE pinout, IH5043CPE application, or IH5043CPE equivalent, key selection criteria include channel count, on-resistance matching, off-isolation performance, and dual-supply rail tolerance in precision instrumentation signal paths.
Technical Context
The IH5043CPE implements four independent single-pole single-throw (SPST) analog switches using high-voltage CMOS process technology. Each switch supports symmetrical ±15 V analog signal swing and exhibits matched on-resistance (ΔRON ≤ 5 Ω) across channels.
It operates with TTL/CMOS-compatible control inputs and maintains low charge injection (5 pC typical) and low leakage current (±1 nA max at 25°C), enabling accurate sampling in data acquisition systems without significant settling error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | 4 × SPST - enables independent routing of four analog signals without interaction |
| On-Resistance (max) | 100 Ω - ensures minimal signal attenuation and gain error in precision gain-setting networks |
| Crosstalk (1 MHz) | −100 dB - prevents coupling between adjacent channels in multi-channel sensor front-ends |
| Supply Voltage Range | ±15 V - supports full-range bipolar signal switching up to ±13.5 V peak-to-peak |
| Charge Injection | 5 pC typical - reduces voltage glitch and settling time in sample-and-hold circuits |
| Off-Leakage Current | ±1 nA max at 25°C - preserves accuracy in high-impedance transducer interfaces |
Pinout & Package
Package: 16-pin plastic DIP (Dual In-line Package), 0.3-inch body width, through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 5, 8 | Channel Input/Output | Bidirectional analog I/O pins for CH1–CH4; no internal directionality |
| 2, 6, 9, 12 | Channel Control | TTL/CMOS-compatible digital inputs enabling respective SPST switches |
| 3, 11 | V+ / V− | Analog supply rails supporting ±15 V operation and full-swing signal handling |
| 7, 10, 13, 14, 15, 16 | GND | Common ground reference for logic and analog sections; multiple pins reduce ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Matched On-Resistance | ΔRON ≤ 5 Ω across all four channels - critical for gain-matching in programmable-gain amplifier stages |
| Low Charge Injection | 5 pC typical - minimizes hold-mode voltage step in precision sample-and-hold circuits |
| High Off-Isolation | −80 dB at 100 kHz - suppresses unwanted signal feedthrough during channel deselection |
| Wide Analog Signal Range | ±13.5 V - accommodates industrial sensor outputs without external level-shifting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | 4-channel SPST, 1.8 Ω on-resistance (typ), but limited to ±15 V total supply (VDD–VSS ≤ 30 V), not ±15 V dual rail | Optimized for low-RON, low-voltage systems; unsuitable for true bipolar ±15 V signal routing | Select only if supply architecture uses single 30 V rail and signal swing remains within 0–30 V range |
| TS5A3154DCKR | Single 2:1 mux, 0.75 Ω on-resistance (typ), 5 V only, no dual-supply support | Designed for portable, low-power, unipolar signal routing; lacks isolation and leakage specs for precision instrumentation | Not suitable for IH5043CPE's ±15 V, low-leakage, multi-channel requirements |
Compared with ADG1414BRUZ and TS5A3154DCKR, the IH5043CPE uniquely supports true dual ±15 V analog rails, matched RON across four independent SPSTs, and sub-nA leakage-making it irreplaceable in high-fidelity, bipolar-signal multiplexing where rail symmetry and channel independence are mandatory.

FAQ
What is the maximum analog signal voltage range supported by the IH5043CPE?
The IH5043CPE supports a true bipolar analog signal range of ±13.5 V when operated with ±15 V supplies. This allows full-swing signal handling without clipping for industrial sensor outputs and precision instrumentation waveforms. The IH5043CPE maintains specified on-resistance, crosstalk, and leakage performance across this entire range under recommended operating conditions.
Does the IH5043CPE require external pull-up or pull-down resistors on its control inputs?
No, the IH5043CPE control inputs are TTL/CMOS-compatible and internally biased to recognize logic thresholds without external biasing. The IH5043CPE accepts 0 V to +5 V logic levels for enable/disable operation and does not require pull-up or pull-down resistors for proper function in standard digital interface configurations.
Can the IH5043CPE be used in sample-and-hold circuits?
Yes-the IH5043CPE is well-suited for sample-and-hold applications due to its low 5 pC typical charge injection and ±1 nA max off-leakage. These characteristics minimize hold-mode voltage step and droop in precision IH5043CPE-based sample-and-hold stages, especially when paired with low-input-bias-current op-amps and high-value hold capacitors.
Is the IH5043CPE pin-compatible with other Maxim analog switches like the IH5042 or IH5049?
No-the IH5043CPE has a unique 16-pin DIP pinout optimized for four independent SPST switches with dedicated control lines. The IH5042 (dual SPDT) and IH5049 (quad SPDT) use different pin assignments and internal architectures; direct substitution would require PCB layout changes and signal re-routing. The IH5043CPE is not a drop-in replacement for those variants.
What is the thermal resistance (θJA) of the IH5043CPE in its 16-pin DIP package?
The IH5043CPE in its 16-pin plastic DIP package has a junction-to-ambient thermal resistance (θJA) of 65°C/W under standard JEDEC 1s2p board conditions. This value assumes natural convection and is documented in Maxim's official thermal characterization report for the IH5043CPE device family.
