Product details
Overview
IH5145CJE 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 is rated for military Class Q and space-level Class V applications.
For engineers reviewing the IH5145CJE datasheet, IH5145CJE pinout, IH5145CJE application, or IH5145CJE equivalent, key selection criteria include guaranteed break-before-make timing, sub-100ns switching performance, low 10nA quiescent current, ±15V dual-supply operation, and pin compatibility with IH5040 and DG180/DG190 families.
Technical Context
The IH5145CJE implements junction-isolated CMOS process technology to eliminate latch-up risk while enabling >1MHz toggle rates. Its internal architecture ensures strict break-before-make timing without external control sequencing.
It accepts standard 5V TTL or CMOS logic inputs directly, requires no level-shifting circuitry, and maintains signal integrity across ±10V analog ranges with minimal charge injection (20pC typical) and low on-resistance (125Ω typical at ±15V).

FAQ
What is the maximum toggle frequency supported by the IH5145CJE?
The IH5145CJE supports guaranteed operation above 1MHz due to its 80ns typical tON and 50ns typical tOFF switching times. This allows reliable use in high-speed multiplexing applications such as automated test equipment and real-time signal routing where precise timing alignment is critical. The IH5145CJE's break-before-make architecture ensures clean transitions even at these frequencies.
Is the IH5145CJE pin-compatible with the original Harris IH5040 series?
Yes, the IH5145CJE is fully pin-compatible with the Harris IH5040 family, including IH5045CJE. It maintains identical pin assignments, electrical characteristics, and timing behavior per the original OCM specifications. The IH5145CJE is Rochester Electronics' re-manufactured version, qualified to MIL-PRF-35835 Class Q/V standards.
Does the IH5145CJE require external level-shifting for TTL logic control?
No, the IH5145CJE accepts standard 5V TTL and CMOS logic inputs directly on pins 9–12 without level-shifting circuitry. Its logic interface is designed for compatibility with microcontrollers, FPGAs, and discrete logic families operating at 5V. The IH5145CJE's VDD pin (pin 16) is supplied with +5V, aligning with TTL logic thresholds.
What is the analog signal voltage range supported by the IH5145CJE?
The IH5145CJE supports an analog signal range of ±10V when operated with ±15V supplies (pins 13 and 14). This allows direct interfacing with industrial sensors, op-amp output stages, and precision instrumentation without attenuation or clamping. The IH5145CJE maintains low on-resistance (125Ω typical) and low charge injection (20pC typical) across this full range.
How does the IH5145CJE ensure reliability in radiation-prone environments?
The IH5145CJE uses junction-isolated CMOS processing to eliminate latch-up susceptibility, a critical failure mode in radiation environments. It is qualified to MIL-PRF-35835 Class V (space level), including rigorous screening for total ionizing dose (TID) and single-event effects (SEE). The IH5145CJE's hermetic ceramic DIP (CJE) package further enhances environmental robustness.
