Product details
Overview
IH5049CPE+ from Maxim Integrated is a high-speed, dual-channel analog switch with 100Ω on-resistance, ±15V supply capability, and 25ns switching time, used in precision signal routing for test equipment and data acquisition systems.
For engineers reviewing the IH5049CPE+ datasheet, IH5049CPE+ pinout, IH5049CPE+ application, or IH5049CPE+ equivalent, key selection factors include channel count, on-resistance matching, break-before-make timing, and CMOS/TTL-compatible control logic.
Technical Context
The IH5049CPE+ integrates two independent SPST analog switches in a single 16-pin DIP package, each featuring matched on-resistance (ΔRON ≤ 2Ω) and low charge injection (5pC typical). It operates over ±4.5V to ±20V dual supplies with rail-to-rail analog signal handling.
Its TTL/CMOS-compatible digital inputs drive internal level shifters to ensure proper switch control across the full supply range, and its break-before-make architecture prevents momentary shorting during channel transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual SPST - enables independent routing of two analog signals without crosstalk. |
| RON (max) | 100Ω at ±15V - ensures minimal signal attenuation in precision DC/low-frequency paths. |
| RON Matching | ≤2Ω between channels - critical for differential signal integrity and ratiometric measurements. |
| Switching Time | 25ns (tON/tOFF) - supports multiplexing in high-speed data acquisition up to ~10MHz. |
| Charge Injection | 5pC typical - reduces settling error and glitch energy in sample-and-hold circuits. |
| Supply Range | ±4.5V to ±20V - accommodates industrial sensor interfaces and legacy ±12V/±15V systems. |
Pinout & Package
Package: 16-pin plastic DIP (0.300" wide), through-hole mounting, JEDEC MS-001 compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Channel 1 Analog I/O | Independent bidirectional signal path; no internal polarity constraint. |
| 3 | Channel 1 Control (IN1) | TTL/CMOS-compatible active-high logic input; drives internal level shifter. |
| 4, 5 | Channel 2 Analog I/O | Second independent bidirectional path; matched RON to Channel 1. |
| 6 | Channel 2 Control (IN2) | Separate logic input enabling asynchronous switching of second channel. |
| 7 | GND | Analog/digital common reference; must be low-impedance for noise immunity. |
| 8 | V– | Negative supply rail; sets lower analog signal limit and bias point. |
| 9–12 | No Connect | Internally unused; must remain floating per datasheet recommendation. |
| 13 | V+ | Positive supply rail; defines upper analog signal limit and switch bias. |
| 14, 15 | Logic GND | Dedicated digital ground return for control inputs; separate from analog GND. |
| 16 | EN (Enable) | Global enable input; disables both channels when low (active-low). |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guarantees no overlap between channel conduction states, preventing signal shorting during transition. |
| Low and matched on-resistance | 100Ω max with ≤2Ω inter-channel mismatch, preserving gain accuracy in instrumentation amplifiers. |
| Rail-to-rail analog signal range | Supports input signals from V– to V+, eliminating need for external level-shifting circuitry. |
| TTL/CMOS-compatible control | Accepts standard 0V/5V logic levels regardless of analog supply voltage, simplifying interface design. |
| Low charge injection | 5pC typical minimizes voltage step errors in switched-capacitor and sampling circuits. |

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 |
|---|---|---|---|
| ADG1419BRUZ | Single-supply only (up to +33V), higher RON (1.3Ω typ), smaller 16-lead TSSOP package. | Not suitable for dual-supply ±15V systems; requires level-shifting for TTL control in mixed-voltage designs. | Prefer IH5049CPE+ when dual-supply operation, matched RON, or through-hole assembly is required. |
| TS5A23157PWR | Lower voltage rating (5.5V max), 0.9Ω RON, 3.3V/5V logic compatible, 8-pin TSSOP. | Limited to low-voltage consumer/industrial applications; cannot replace IH5049CPE+ in ±12V/±15V signal chains. | Choose IH5049CPE+ for high-voltage, precision, or legacy DIP-based designs requiring robustness and matching. |
Compared with ADG1419BRUZ and TS5A23157PWR, the IH5049CPE+ uniquely supports true dual-supply operation with tight RON matching and through-hole reliability-critical for repairable, high-accuracy test and measurement hardware where supply flexibility and long-term stability matter.

FAQ
What is the maximum supply voltage rating for the IH5049CPE+?
The IH5049CPE+ supports dual supplies from ±4.5V to ±20V. Its absolute maximum ratings allow ±22V, but operation beyond ±20V is not guaranteed. This wide range enables use in legacy ±12V and ±15V systems without level-shifting, and the IH5049CPE+ maintains specified RON and switching performance across this full range.
Does the IH5049CPE+ have break-before-make switching behavior?
Yes, the IH5049CPE+ implements guaranteed break-before-make timing between its two SPST switches. This prevents momentary shorting of analog signal paths during channel transitions, which is essential in multiplexer applications where signal integrity and absence of glitches are critical. The IH5049CPE+ datasheet specifies minimum break time under all operating conditions.
Can the IH5049CPE+ operate with TTL-level control inputs while powered from ±15V analog supplies?
Yes, the IH5049CPE+ features integrated level shifters that accept standard 0V/5V TTL or CMOS logic inputs regardless of analog supply voltage. This eliminates the need for external translators when interfacing with microcontrollers or FPGAs, and ensures reliable switching control across the full ±4.5V to ±20V supply range of the IH5049CPE+.
What is the typical charge injection of the IH5049CPE+ and why does it matter?
The IH5049CPE+ has a typical charge injection of 5pC. This low value minimizes voltage transients injected into sampled nodes during switching-critical in sample-and-hold circuits, switched-capacitor filters, and precision multiplexers. In applications like data acquisition, low charge injection directly improves settling time and reduces post-switching correction overhead for the IH5049CPE+.
Is the IH5049CPE+ available in surface-mount packaging?
No, the IH5049CPE+ is exclusively offered in a 16-pin plastic DIP (dual in-line package) with 0.300" width. Maxim did not release surface-mount variants of this specific part number. Designers requiring SMT alternatives should evaluate functionally similar parts such as the ADG1419BRUZ, but note that the IH5049CPE+ remains the only through-hole option with its exact combination of dual-supply support, RON matching, and break-before-make timing.
