HI-3002PCTF

Overview

The HI-3002PCTF is a dual bus transceiver manufactured by Holt Integrated Circuits. It integrates two differential line transceivers on a single CMOS chip, designed for robust data communication in demanding environments. The device operates within an extended temperature range of -55°C to 125°C and supports a single supply voltage with a typical value of 3.3V, ranging from 3.15V to 3.45V. Housed in a 48-pin PQFP surface-mount package measuring 7mm in length and 1.4mm in height, it provides electrical isolation between the bus lines and the logic interface.

Feature Summary

• On-chip integration of dual differential bus transceivers for compact system design
• Extended industrial and military-grade temperature operation capability
• CMOS process technology ensuring low power consumption and high noise immunity

Applications

• Avionics flight control systems requiring MIL-STD-1553B compliance
• Military embedded data bus networks
• Industrial automation controllers operating in harsh environments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Confirm that the 48-pin PQFP package matches the target PCB footprint. Ensure the supplier provides traceability documentation suitable for aerospace or defense procurement requirements.

Selection Notes

Select this component when a dual-channel differential interface is required within a single package footprint. Compare against the HI-6135PQTF if identical pinouts are needed but different electrical characteristics are acceptable. Verify that the 3.3V supply requirement aligns with the system power architecture before finalizing the design.

Part Context

This part belongs to the Holt Integrated Circuits family of data bus communication ICs, which serve the aerospace, military, and industrial sectors. The company specializes in mixed-signal solutions for embedded applications, including MIL-STD-1553 and ARINC 429 interfaces. This series supports critical infrastructure where reliability and environmental resilience are paramount.

Replacement Considerations

The HI-6135PQTF is a documented alternative within the same product family offering similar dual transceiver functionality. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
