HI-4853PSTF

Overview

The HI-4853PSTF is a line transceiver manufactured by Holt Integrated Circuits Inc. It features two transmitters and two receivers, utilizing differential signal types for both transmission and reception. The device is built on CMOS process technology and operates with a single power supply. It supports an extended temperature range from -55°C to 125°C. The component is housed in a 48-pin PQFP surface-mount package with dimensions of 7mm length and 1.4mm height.

Feature Summary

• Dual differential bus transceiver architecture
• Extended industrial and military temperature rating
• Single supply voltage operation

Applications

• Avionics data bus systems
• Flight control interfaces
• Engine management communication

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the procurement channel provides traceability documentation required for aerospace and defense applications. Confirm RoHS compliance status as per the latest regulatory updates before finalizing purchase orders.

Selection Notes

Select this component when designing systems requiring dual differential channels within a compact PQFP footprint. The wide operating temperature range makes it suitable for harsh environments where standard commercial grade parts would fail. Verify that the system power budget aligns with the single-supply requirement and that the 48-pin package fits the PCB layout constraints.
