The HS-3282 is a high performance CMOS bus interface circuit that is intended to meet the requirements of ARINC Specification 429, and similar encoded, time multiplexed serial data protocols. This device is intended to be used with the HS-3182, a monolithic Dl bipolar differential line driver designed to meet the specifications of ARINC 429. The ARINC 429 bus interface circuit consists of two (2) receivers and a transmitter operating independently. The two receivers operate at a frequency that is ten (10) times the receiver data rate, which can be the same or different from the transmitter data rate. Although the two receivers operate at the same frequency, they are functionally independent and each receives serial data asynchronously. The transmitter section of the ARINC bus interface circuit consists mainly of a First-In First-Out (FIFO) memory and timing circuit.
The HS-3282 is a high‑performance CMOS ARINC 429 bus interface circuit that provides two independent receivers and a transmitter in a single low‑power LSI device. It supports ARINC Specification 429 as well as similar serial data protocols, offering selectable word lengths, parity options, and a wide temperature range.
Key features include data rates of 100 kbps or 12.5 kbps, selectable 25‑ or 32‑bit word lengths, a single 5 V supply, and operation over a full military temperature range. The device is available in CERDIP and CLCC packages and includes a comprehensive pinout and control‑word interface for flexible system integration.
