HI-1573PSIF

Overview

The HI-1573PSIF is a low-power CMOS dual transceiver manufactured by Holt Integrated Circuits Inc. It is designed to meet MIL-STD-1553 and ARINC 708A specifications. The device operates on a single 3.3V supply, with a voltage range of 3.15V to 3.45V. It features two independent transmitter/receiver channels for bidirectional data bus communication. The component is housed in a 20-pin ESOIC (Exposed Pad Small Outline Integrated Circuit) package with dimensions of 0.295 inches (7.50mm) width. It supports surface mount installation and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Compliance with MIL-STD-1553A/B and ARINC 708A standards
• Single 3.3V power supply operation
• Low power dissipation under 0.5W
• Exposed pad package for thermal management

Applications

• MIL-STD-1553 data bus systems
• ARINC 708A avionics interfaces
• Military and aerospace communication modules

Procurement Notes

Verify the exact suffix 'PSIF' against the manufacturer's official datasheet to confirm the specific tape-and-reel packaging and temperature grade. Ensure the exposed pad configuration matches the target PCB footprint requirements. Confirm RoHS compliance status through the current production documentation provided by Holt Integrated Circuits.

Selection Notes

Select this component when a 3.3V powered, dual-channel MIL-STD-1553 transceiver is required in a small outline package. Compare pinout compatibility with existing designs using the 20-pin ESOIC form factor. Verify that the industrial temperature range (-40°C to 85°C) meets the environmental constraints of the intended application environment.

Part Context

The HI-1573 series includes variants such as HI-1573PCIF (QFN) and HI-1573CDI (DIP). The PSIF variant specifically denotes the plastic small outline package with an exposed thermal pad. This family serves as a monolithic solution for replacing discrete transistor-based transceivers in legacy MIL-STD-1553 architectures.

Replacement Considerations

Direct replacements include HI-1573PCI or HI-1573PSM if package compatibility allows. Verify pin-to-pin equivalence before substitution. Check if the alternative package offers identical thermal performance and electrical characteristics for the specific bus load conditions.
