Mission Viejo, CA (January 16, 2014) - Holt Integrated Circuits announced the introduction of a new ARINC 429 line receiver family with fully integrated lightning protection circuitry. The built-in circuitry ensures compliance with RTCA/DO-160G, Section 22 Level 3 Pin Injection Test Waveform Set A (3 & 4), Set B (3 & 5A) and Set Z (3 & 5B), enabling direct connection to the ARINC 429 bus without external components. All devices operate from a 3.3V or 5.0V supply.
The new family comprises four devices: two single-channel receivers, HI-8450 and HI-8451 in an industry standard 8-pin SOIC package, and two quad-channel devices, HI-8454 and HI-8455 in a 20-pin TSSOP package or a 5mm square 32-pin QFN package. Each device has two test input pins which bypass analog inputs for test purposes. In the case of HI-8450, pulling both test pins high forces the receiver outputs to a high impedance state.
The new HI-8450, HI-8451 and HI-8454, HI-8455 are pin-compatible with Holt’s already popular ARINC 429 receivers HI-8591, HI-8588 and HI-8444, HI-8445 respectively. The new devices eliminate external lightning-protection input resistors, yet fully comply with RTCA/DO-160G Level 3 lightning requirements.
“Many recently introduced Holt products integrate previously external circuitry,” said George Noh, Director of Sales and Marketing at Holt. “Our strategy adds features like internal lightning protection, hardware-programmed “no MCU” operation, and on-chip DC/DC conversion for single supply operation to provide our customers with substantial cost and space savings.”
These devices are available in industrial −40oC to +85oC and extended −55oC to +125oC temperature ranges, with optional burn-in available for extended temperature range devices.
