Product details
Overview
IH5050CPE+ 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 IH5050CPE+ datasheet, IH5050CPE+ pinout, IH5050CPE+ application, or IH5050CPE+ equivalent, key selection criteria include channel count, on-resistance matching, break-before-make timing, and TTL/CMOS-compatible control logic.
Technical Context
The IH5050CPE+ integrates two independent SPST analog switches in a single 16-pin plastic DIP package, each featuring matched on-resistance (ΔRON ≤ 2Ω) and low charge injection (0.5pC). It operates over ±4.5V to ±20V dual supplies with guaranteed performance at ±15V.
Its control inputs accept TTL- and CMOS-level signals, enabling direct interface with microcontrollers and FPGAs without level-shifting. The device exhibits no latch-up under normal operating conditions and supports rail-to-rail analog signal switching.
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 measurement paths. |
| RON Matching | ≤2Ω - maintains amplitude consistency between channels in differential or dual-path systems. |
| Switching Time | 25ns (tON/tOFF) - supports multiplexing of signals up to ~10MHz without edge distortion. |
| Charge Injection | 0.5pC - reduces settling error in sample-and-hold and ADC front-end applications. |
| Supply Range | ±4.5V to ±20V - accommodates industrial sensor interfaces and legacy ±15V instrumentation rails. |
Pinout & Package
Package: 16-pin plastic DIP (0.300" wide), through-hole mounting, JEDEC MS-001 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Channel 1 Input/Output | Bi-directional analog path; symmetric RON allows either terminal as input or output. |
| 3 | Channel 1 Control (IN1) | TTL/CMOS-compatible digital input; active-high enables Channel 1 switch. |
| 4, 5 | Channel 2 Input/Output | Independent bi-directional analog path; electrically isolated from Channel 1. |
| 6 | Channel 2 Control (IN2) | TTL/CMOS-compatible digital input; active-high enables Channel 2 switch. |
| 7 | GND | Analog/digital common reference; must be connected to system ground plane. |
| 8 | V– | Negative supply rail; required for full ±15V operation and signal swing. |
| 9–12 | No Connect | Internally unused; must remain unconnected per datasheet. |
| 13 | V+ | Positive supply rail; powers internal logic and switch driver circuitry. |
| 14, 15 | Channel 1 Output/Input | Redundant I/O terminals for Channel 1; electrically identical to Pins 1 and 2. |
| 16 | Enable (EN) | Global enable input; low disables both channels simultaneously. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 5ns minimum break time prevents momentary shorting during channel transitions. |
| Low off-leakage current | 1nA max at 25°C - preserves accuracy in high-impedance sensor and integrator circuits. |
| Matched on-resistance | ≤2Ω channel-to-channel mismatch - critical for gain-matching in dual-path instrumentation. |
| Rail-to-rail analog range | Supports signals from V– to V+ - eliminates need for external level-shifting in ±15V systems. |
| TTL/CMOS-compatible control | Direct interface with 5V logic families - simplifies digital control without external buffers. |

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 36V); higher RON (1.3Ω typical); 10ns faster switching. | Requires level-shifting for ±15V signal paths; better suited for battery-powered, low-voltage systems. | Select ADG1419BRUZ when single-supply operation and sub-10ns switching dominate over bipolar rail support. |
| TS5A3159DCKR | Lower voltage rating (5.5V max); smaller SC70-6 package; 0.7Ω RON; 10ns switching. | Not suitable for ±15V instrumentation; intended for portable consumer electronics with 3.3V logic. | Choose TS5A3159DCKR only for space-constrained, low-voltage, high-speed signal routing where bipolar supplies are absent. |
Compared with ADG1419BRUZ and TS5A3159DCKR, the IH5050CPE+ uniquely supports true ±15V analog signal handling with matched RON and break-before-make timing-making it irreplaceable in legacy industrial and test equipment requiring bipolar rail compatibility and channel matching.

FAQ
What is the maximum supply voltage rating for the IH5050CPE+?
The IH5050CPE+ supports dual supplies from ±4.5V to ±20V, with full specification guaranteed at ±15V. Exceeding ±20V risks permanent damage. The IH5050CPE+ must have both V+ and V– rails properly decoupled with 0.1µF ceramic capacitors close to Pins 8 and 13 to ensure stable switching behavior and prevent oscillation.
Does the IH5050CPE+ support rail-to-rail analog signal switching?
Yes, the IH5050CPE+ supports rail-to-rail analog signal switching across its full specified supply range (±4.5V to ±20V). Signals from V– to V+ pass through the switch with minimal distortion, making the IH5050CPE+ suitable for applications such as ±10V sensor interfaces and precision DAC output routing without external level-shifting circuitry.
What is the purpose of the NC pins (9–12) on the IH5050CPE+?
Pins 9–12 on the IH5050CPE+ are internally not connected and serve no electrical function. They must remain unconnected in PCB layout to avoid unintended coupling or mechanical stress. These pins exist solely for mechanical symmetry and package standardization in the 16-pin DIP footprint; their presence does not affect the operation or performance of the IH5050CPE+.
How does the global enable (EN) pin function on the IH5050CPE+?
The EN pin (Pin 16) on the IH5050CPE+ provides system-level control: when pulled low, it disables both analog switches regardless of IN1/IN2 states, forcing open-circuit isolation. When high, individual channel control via IN1 and IN2 resumes. This feature allows safe power-down sequencing and fault containment in multi-channel IH5050CPE+ systems without modifying individual control lines.
Is the IH5050CPE+ pin-compatible with other Maxim analog switches like the IH5049?
No, the IH5050CPE+ is not pin-compatible with the IH5049. The IH5049 is a quad SPST switch in a 16-pin package with different pin assignments, including separate V+ and V– for each pair of switches. The IH5050CPE+ uses a shared dual-supply configuration and global EN, resulting in distinct pinout and control architecture-requiring dedicated PCB layout for the IH5050CPE+.
