This document describes the data bus modules ARX4404 and ARX4407 from Aeroflex CIRCUIT TECHNOLOGY. These modules comply with MIL-STD-1553A and B, Macair A3818, A4905, A5232, and A5690 specifications. They feature bipolar supply of ±15V to ±12V, logic supply of +5V, and are direct replacements for CT3231 and CT3232. The modules are monolithic constructions using linear ASICs and have variable receiver threshold capability. The products are processed and screened to MIL-STD-883 specifications.
The ARX4404 and ARX4407 transceivers are designed for MIL‑STD‑1553A/B and Macair (A‑3818, A‑4905, A‑5232, A‑5690) data bus applications. They offer direct replacement for older CT3231/CT3232 parts and feature monolithic ASIC construction with active filter designs for low error rates.
The datasheet lists absolute maximum ratings, power supply requirements, driver peak output current (300 mA), differential output levels (≈7.5 Vp‑p), and detailed pin assignments for both plug‑in and flat‑pack packages. Ordering information and configuration options are also provided.
