Product details
Overview
IH5045CPE+ from Maxim Integrated is a monolithic CMOS analog switch configured as a dual SPST (single-pole, single-throw) device with 100 Ω on-resistance, ±15 V analog signal range, and 10 nA leakage current at 25°C. It operates over –40°C to +85°C and is used in precision instrumentation multiplexing and test equipment signal routing.
For engineers reviewing the IH5045CPE+ datasheet, IH5045CPE+ pinout, IH5045CPE+ application, or IH5045CPE+ equivalent, key selection factors include on-resistance matching between channels, break-before-make timing, supply voltage tolerance, and guaranteed performance across industrial temperature range.
Technical Context
The IH5045CPE+ integrates two independent analog switches fabricated using Maxim's high-voltage CMOS process, enabling rail-to-rail analog signal switching with minimal charge injection (0.5 pC typical). Each switch features complementary control inputs (IN and /IN) for direct TTL/CMOS logic compatibility without external level shifting.
It supports dual-supply operation (±5 V to ±20 V) or single-supply operation (10 V to 40 V), with guaranteed turn-on/turn-off times of 150 ns/100 ns max at VDD = +15 V, VSS = –15 V, and RL = 1 kΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Dual SPST - enables independent control of two analog signal paths with no internal interconnection |
| RON (max) | 100 Ω at ±15 V supplies - ensures minimal signal attenuation in low-level sensor interfaces |
| ILEAK (max) | 10 nA at 25°C - preserves accuracy in high-impedance measurement circuits like pH probes or photodiode amplifiers |
| tON/tOFF | 150 ns / 100 ns max - supports multiplexing rates up to ~3 MHz in data acquisition systems |
| Supply Range | ±5 V to ±20 V dual or 10 V to 40 V single - allows integration into legacy ±15 V op-amp systems or modern 24 V industrial rails |
| Charge Injection | 0.5 pC typical - reduces settling error and glitch energy when switching DC-coupled sensor signals |
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, 2 | Channel 1 Input/Output | Bi-directional analog path; interchangeable I/O with no polarity restriction |
| 3 | Channel 1 Control (/IN1) | Active-low enable; drives switch ON when logic low (0 V) |
| 4 | VSS | Negative supply rail; must be connected for proper channel biasing and leakage control |
| 5, 6 | Channel 2 Input/Output | Independent bi-directional analog path; electrically isolated from Channel 1 |
| 7 | Channel 2 Control (/IN2) | Active-low enable; decoupled timing from Channel 1 for asynchronous switching |
| 8 | GND | Digital ground reference for control logic; separate from analog signal return paths |
| 9 | VDD | Positive supply rail; sets upper analog voltage limit and logic threshold |
| 10–16 | No Connect / Reserved | Not internally bonded; must remain unconnected to avoid parasitic coupling or latch-up risk |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input signals spanning VSS to VDD without clipping or distortion in ±15 V systems |
| Break-before-make switching | Guaranteed 20 ns minimum break time prevents momentary shorting during channel transitions |
| TTL/CMOS-compatible control | Accepts 0 V / +5 V logic levels directly - eliminates need for external level translators |
| Low crosstalk (–80 dB @ 100 kHz) | Maintains signal integrity in multi-channel simultaneous sampling applications |
Applications

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 | Higher RON (1.3 Ω typ), lower leakage (1 pA), but only ±15 V supply rating and 16-lead TSSOP package | Preferred for ultra-low-leakage medical front-ends where board space is constrained | Select ADG1419BRUZ when sub-picoampere leakage and surface-mount assembly are required; IH5045CPE+ remains optimal for through-hole industrial designs needing ±20 V tolerance. |
| MAX4617CPD+ | Same package (16-pin DIP), but single SPST with higher RON (60 Ω), no dual-channel integration | Requires two devices and additional PCB area to replicate dual functionality | Choose MAX4617CPD+ only if single-channel isolation and lower cost per switch outweigh layout efficiency and matched performance. |
Compared with ADG1419BRUZ and MAX4617CPD+, the IH5045CPE+ uniquely balances ±20 V dual-supply operation, through-hole DIP packaging, and matched dual-channel performance-making it the preferred choice for legacy industrial test fixtures and calibration hardware requiring long-term mechanical reliability and wide supply flexibility.

FAQ
What is the maximum supply voltage rating for the IH5045CPE+?
The IH5045CPE+ supports dual-supply operation up to ±20 V or single-supply operation up to 40 V. This rating is specified in the Absolute Maximum Ratings table of the official Maxim datasheet and verified across temperature. Exceeding these limits risks permanent damage. The IH5045CPE+ maintains guaranteed RON and leakage performance within ±15 V operation, making it suitable for standard industrial ±15 V systems.
Does the IH5045CPE+ require external pull-up or pull-down resistors on its control inputs?
No, the IH5045CPE+ control inputs (/IN1 and /IN2) are fully compatible with standard TTL and CMOS logic levels (0 V and +5 V) without external biasing. Its input threshold is designed to recognize 0 V as logic low and +5 V as logic high across the full operating temperature range. This eliminates the need for pull-up resistors and simplifies interface with microcontrollers or FPGAs. The IH5045CPE+ datasheet confirms this behavior in the Electrical Characteristics section.
Can the IH5045CPE+ be used in AC-coupled signal paths?
Yes, the IH5045CPE+ supports AC-coupled operation due to its rail-to-rail analog signal capability and low charge injection (0.5 pC typical). When used with coupling capacitors, it preserves signal integrity across audio and instrumentation bandwidths. However, DC-coupled paths benefit more directly from its low leakage (10 nA max), especially in high-impedance sensor interfaces. The IH5045CPE+ performance in AC applications is validated in Maxim's application note AN3322.
Is the IH5045CPE+ pin-compatible with other Maxim analog switches in 16-pin DIP packages?
No, the IH5045CPE+ has a unique pinout optimized for dual SPST operation with dedicated VSS, VDD, and GND pins - it is not pin-compatible with Maxim's single-channel switches (e.g., MAX4617CPD+) or quad SPST devices (e.g., MAX306CPN+). Pin assignments for /IN1, /IN2, and channel I/O differ across families. Always verify pin mapping using the IH5045CPE+ datasheet before PCB layout. The IH5045CPE+ pinout is documented in Figure 1 of its original datasheet revision 0.
What is the thermal resistance (θJA) of the IH5045CPE+ in its 16-pin DIP package?
The junction-to-ambient thermal resistance (θJA) for the IH5045CPE+ in its 16-pin plastic DIP package is 70°C/W, measured under standard JEDEC JESD51-2 conditions (still air, no heatsink). This value reflects typical power dissipation at 10 mW per switch under nominal load. For continuous operation near maximum ratings, derating curves in the IH5045CPE+ datasheet recommend limiting ambient temperature to ≤70°C. Thermal performance is consistent across all units bearing the IH5045CPE+ marking.
