Product details
Overview
IH5143MJE from Rochester Electronics is a high-speed, latch-free CMOS analog switch with 80ns typical tON, 50ns typical tOFF, break-before-make switching action, and TTL/CMOS logic compatibility. It operates from ±15V supplies, supports ±10V analog signal swing, and delivers low 10nA typical quiescent current - ideal for precision military data acquisition systems requiring fast, reliable signal routing.
For engineers reviewing the IH5143MJE datasheet, IH5143MJE pinout, IH5143MJE application, or IH5143MJE equivalent, key selection criteria include guaranteed break-before-make timing, ±15V dual-supply operation, sub-100ns switching speed, low leakage in OFF state, and direct compatibility with TTL and CMOS control logic without level shifting.
Technical Context
The IH5143MJE implements a monolithic CMOS analog switch architecture using Harris' junction-isolated process to eliminate latch-up risk. It features complementary MOSFET pairs per channel with matched threshold voltages, enabling symmetrical ON-resistance (<100Ω) and low charge injection (5pC typical).
Its control inputs accept 0–5V logic levels independent of analog supply rails, and internal clamping diodes protect against overvoltage transients up to ±20V. The device guarantees break-before-make timing across temperature (−55°C to +125°C) and supply voltage variations.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Harris IH5143CD | Plastic DIP package; not MIL-qualified; rated only to +85°C | Suitable for commercial benchtop test equipment, not deployed avionics | Select IH5143MJE when Class Q qualification, hermetic sealing, or extended temperature range is mandatory |
| Intersil DG181DJ | Same pinout; 100ns tON; higher 200Ω RON; no guaranteed break-before-make | Acceptable for non-critical multiplexing where channel crosstalk is tolerable | Choose IH5143MJE where guaranteed timing margin and low RON flatness are required for precision measurement |
Compared with IH5143CD and DG181DJ, the IH5143MJE uniquely combines military-grade packaging, guaranteed break-before-make timing, and sub-100ns switching - making it the only option qualified for flight-critical analog signal routing in Class Q environments.

FAQ
What is the maximum analog signal voltage range supported by the IH5143MJE?
The IH5143MJE supports an analog signal range of ±10V when operated with ±15V supplies. Its rail-to-rail analog capability allows full utilization of the supply headroom without clipping, and internal protection structures withstand transient overvoltages up to ±20V - critical for ruggedized military signal paths where the IH5143MJE is commonly deployed.
Does the IH5143MJE require external pull-up or pull-down resistors on its logic inputs?
No, the IH5143MJE logic inputs are TTL/CMOS compatible and internally biased to recognize 0–0.8V as logic low and 2.0–5.0V as logic high without external biasing. This eliminates the need for pull-up resistors in microcontroller- or FPGA-driven systems, simplifying layout and reducing BOM count - a key advantage confirmed in the IH5143MJE datasheet and widely applied in compact crypto module designs.
Is the IH5143MJE pin-compatible with the Harris IH5040 family?
Yes, the IH5143MJE is explicitly stated as pin-compatible with the Harris IH5040 family. This compatibility enables drop-in replacement in legacy designs originally specified with IH5040-series switches, preserving PCB layout and firmware while upgrading to the faster switching speeds and improved reliability of the IH5143MJE - a documented migration path used in radar upgrade programs.
What is the guaranteed break-before-make time specification for the IH5143MJE?
The IH5143MJE guarantees break-before-make operation across its full operating temperature and voltage range, with minimum separation time exceeding 20ns between channel turn-off and turn-on events. This timing margin is built into the internal driver design and verified per MIL-STD-883 test methods - ensuring signal integrity in the IH5143MJE's target applications such as avionics multiplexing where channel crosstalk must be avoided.
Can the IH5143MJE operate from a single +15V supply instead of dual ±15V?
No, the IH5143MJE requires dual ±15V supplies to function correctly. Its internal switch architecture relies on symmetrical rail voltages to maintain matched RON, low distortion, and guaranteed break-before-make timing. Operation from a single supply violates the absolute maximum ratings and results in undefined behavior - a constraint clearly defined in the IH5143MJE datasheet and critical for proper implementation in radar front-end designs.
