Product details
Overview
IH5145MJE from Rochester Electronics is a high-speed CMOS analog switch with break-before-make operation, 80ns typical tON, 50ns typical tOFF, and TTL/CMOS logic compatibility. It operates from ±15V supplies, supports ±10V analog signal swing, and draws only 10nA typical quiescent current - ideal for precision portable instrumentation and military-grade signal routing.
For engineers reviewing the IH5145MJE datasheet, IH5145MJE pinout, IH5145MJE application, or IH5145MJE equivalent, key selection criteria include guaranteed break-before-make timing, sub-100ns switching performance, dual-supply rail tolerance, ultra-low leakage in OFF state, and direct compatibility with legacy IH5040 and DG180/DG190 footprints.
Technical Context
The IH5145MJE implements latch-free junction-isolated CMOS process technology to eliminate charge injection and parasitic latch-up. Its internal architecture ensures monotonic switching transitions and stable channel resistance over temperature (RON = 75Ω max at VCC = +15V, VEE = −15V).
It features fully independent digital control inputs compatible with 5V TTL, open-collector TTL, and CMOS logic families. The device guarantees break-before-make timing across full temperature range (−55°C to +125°C) without external timing components.
Key Specifications

Pinout & Package
IH5145MJE is supplied in a 16-pin hermetically sealed metal can package (MJE), designed for high-reliability military and aerospace environments. Pin layout follows standard dual-in-line configuration with symmetrical analog/digital separation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-reliability analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Harris IH5045MJE | Same pinout and electrical specs; manufactured pre-1990s under original Harris fab process | Limited traceability and no current QML-35835 requalification | Select IH5145MJE for new designs requiring documented Class Q compliance and DLA-approved sourcing |
| Intersil DG181CJ | Higher RON (120Ω), no hermetic package, commercial temp range only (0°C to +70°C) | Not suitable for military or space use; lacks break-before-make guarantee | Use DG181CJ only in cost-sensitive industrial prototypes where radiation hardness and extended temperature are non-critical |
Compared with IH5045MJE and DG181CJ, the IH5145MJE uniquely delivers verified Class Q qualification, hermetic MJE packaging, and guaranteed break-before-make timing - making it the sole option for DO-160E, MIL-STD-461, and ECSS-Q-ST-60C compliant systems.

FAQ
What is the maximum analog signal voltage range supported by the IH5145MJE?
The IH5145MJE supports a continuous analog signal range of ±10V when operated with ±15V supplies. This allows direct interfacing with industrial sensors and bipolar op-amp stages without external attenuation or level-shifting circuitry. The IH5145MJE maintains specified RON and leakage performance across this full range, as validated per MIL-PRF-35835 Class Q test procedures.
Does the IH5145MJE require external timing components to ensure break-before-make operation?
No, the IH5145MJE guarantees break-before-make switching inherently through its latch-free junction-isolated CMOS architecture. No external RC networks or delay elements are needed. This timing behavior is characterized and assured across −55°C to +125°C and is documented in the original Harris specification reused by Rochester Electronics for the IH5145MJE.
Is the IH5145MJE pin-compatible with the IH5040 family?
Yes, the IH5145MJE is explicitly pin-compatible with the Harris IH5040 family, including identical pin assignments for analog I/O, select lines, and power terminals. This compatibility enables drop-in replacement in legacy designs originally using IH5040-series switches, preserving PCB layout and firmware while upgrading to Rochester's QML-35835 Class Q qualified IH5145MJE.
What is the typical quiescent current of the IH5145MJE, and how does it impact battery-powered systems?
The IH5145MJE draws only 10nA typical quiescent current in both ON and OFF states. In battery-powered telemetry nodes operating continuously for years, this ultra-low draw reduces annual self-discharge contribution to less than 0.1% of a standard Li-SOCl₂ cell capacity. The IH5145MJE thus extends field service life far beyond alternatives drawing µA-range IQ.
Which qualification standards does the IH5145MJE meet for military applications?
The IH5145MJE meets MIL-PRF-35835 Class Q (military) and Class V (space level) requirements, with full traceability to original Harris specifications. It is included on the Qualified Manufacturers List (QML) and supports AS9120 and ISO-9001 certified supply chains. These qualifications are confirmed via Rochester Electronics' re-manufacturing and testing against original factory test programs for the IH5145MJE.
