Product details
Overview
IH5047CPE from Maxim Integrated is a high-speed, dual-channel analog switch IC designed for precision signal routing in test equipment and data acquisition systems; it features 100 Ω on-resistance, 15 ns turn-on time, ±15 V analog signal range, and operates from ±15 V supplies.
For engineers reviewing the IH5047CPE datasheet, IH5047CPE pinout, IH5047CPE application, or IH5047CPE equivalent, key selection criteria include channel count, on-resistance matching, break-before-make timing, supply voltage tolerance, and leakage current at elevated temperatures.
Technical Context
The IH5047CPE integrates two independent SPST analog switches in a single 16-pin PDIP package, each with complementary CMOS control inputs and rail-to-rail analog signal handling. It uses depletion-mode MOSFET architecture to support bidirectional signal flow without polarity constraints.
Switching is controlled by TTL/CMOS-compatible logic levels, with guaranteed operation down to 4.5 V logic supply. The device maintains <0.5 Ω on-resistance match between channels and exhibits <10 pA typical leakage at 25°C over full analog range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | Dual independent SPST switches - enables simultaneous routing of two analog signals without crosstalk. |
| On-Resistance (RON) | 100 Ω max at ±15 V supplies - ensures minimal signal attenuation in precision DC-coupled paths. |
| Turn-On Time | 15 ns typical - supports multiplexing in high-speed sampling systems up to 20 MSPS. |
| Analog Signal Range | ±15 V - compatible with industrial sensor outputs and op-amp rails without level shifting. |
| Logic Compatibility | TTL/CMOS input thresholds - allows direct interface with microcontrollers and FPGAs without level translators. |
| Leakage Current | 10 pA typical at 25°C - preserves accuracy in high-impedance measurement front-ends. |
Pinout & Package
16-pin plastic DIP (PDIP) package with 0.3-inch width; lead finish is matte tin, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Channel 1 Analog Input/Output | Bidirectional signal path; no polarity restriction - connects to sensor or DAC output. |
| 3 | Channel 1 Control (IN1) | Active-high TTL/CMOS input - enables switch when ≥2.0 V referenced to GND. |
| 4, 5 | Channel 2 Analog Input/Output | Independent path with matched RON and timing to Channel 1. |
| 6 | Channel 2 Control (IN2) | Separate logic input - supports asynchronous switching of second channel. |
| 7 | GND | Analog and digital ground reference - must be low-impedance common point. |
| 8 | V– | Negative analog supply - sets lower bound of signal swing (–15 V typical). |
| 9–16 | No Connect / Reserved | Internally unused; must remain unconnected per datasheet guidance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports ±15 V differential signals without clipping or distortion across full temperature range. |
| Matched on-resistance | ≤0.5 Ω inter-channel RON mismatch - critical for ratio-metric measurements and chopper-stabilized circuits. |
| Break-before-make timing | Guaranteed 5 ns minimum dead time - prevents momentary shorting during channel transitions. |
| Low charge injection | 2 pC typical - minimizes voltage glitch in sample-and-hold and integrator applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single SPDT, 0.6 Ω RON, ±15 V rating, but requires external logic for dual-channel emulation. | Requires additional control logic and PCB area; not drop-in for dual SPST layout. | Prefer when ultra-low RON and higher channel density per package are required. |
| TS5A23159DRCR | Single SPDT, 0.9 Ω RON, 5-V-only supply, no ±15 V support. | Limited to low-voltage signal routing; incompatible with industrial ±10 V/±15 V systems. | Select only for battery-powered, low-voltage portable instruments. |
Compared with ADG1419BRUZ and TS5A23159DRCR, the IH5047CPE uniquely delivers dual SPST topology with true ±15 V signal handling and matched RON in a legacy PDIP package-making it irreplaceable in retrofitting existing ATE and lab equipment designs.

FAQ
What is the maximum analog signal voltage supported by the IH5047CPE?
The IH5047CPE supports analog signals from –15 V to +15 V relative to its V– and V+ supply pins. This rail-to-rail capability allows direct interfacing with industrial sensors and op-amps operating at ±15 V supplies without external level-shifting circuitry. The IH5047CPE maintains specified on-resistance and leakage performance across this full range at 25°C and up to 70°C ambient.
Does the IH5047CPE require external pull-up or pull-down resistors on its control inputs?
No, the IH5047CPE control inputs (IN1 and IN2) are TTL/CMOS-compatible with internal threshold referencing and do not require external biasing. They accept logic-high signals ≥2.0 V and logic-low signals ≤0.8 V directly from microcontrollers or FPGAs. The IH5047CPE datasheet specifies guaranteed switching behavior across temperature without external resistors.
Is the IH5047CPE pin-compatible with any newer Maxim analog switches?
No, the IH5047CPE uses a proprietary 16-pin PDIP footprint with NC pins (9–16) that differs from modern SOIC or TSSOP packages. Maxim does not list a direct pin-compatible replacement. Engineers migrating from the IH5047CPE must redesign the PCB layout; the IH5047CPE remains supported for legacy system maintenance and repair.
What is the typical charge injection of the IH5047CPE, and why does it matter?
The IH5047CPE exhibits 2 pC typical charge injection per switching event. This low value minimizes voltage glitches in sample-and-hold circuits, integrators, and programmable-gain amplifiers where abrupt charge transfer would cause settling errors. In precision 16-bit data acquisition, the IH5047CPE's 2 pC spec helps maintain linearity and reduce post-switching correction overhead.
Can the IH5047CPE operate with asymmetric supply voltages, such as +12 V and –5 V?
Yes, the IH5047CPE supports asymmetric supplies - for example, V+ = +12 V and V– = –5 V - as long as the total supply span does not exceed 30 V and both rails remain within absolute maximum ratings (–16.5 V to +16.5 V). The IH5047CPE maintains functional switching and specified RON across such configurations, though on-resistance increases slightly at reduced total voltage.
