HC55185FCRZ

Telecom Overview

The Intersil HC55185FCRZ is a high-speed, low-power CMOS hex bus transceiver designed for bidirectional data transfer between two buses. It operates with a supply voltage range of 2.7V to 3.6V and features three-state outputs to isolate the device when disabled. The component supports a maximum data rate of 100 Mbps and includes an output enable pin (OE) and direction control pin (DIR). It is housed in a 24-pin TSSOP package with a lead-free finish, suitable for applications requiring reliable data transmission in low-voltage digital systems.

Telecom Feature Summary

• Bidirectional data transfer capability between two independent buses
• Low power consumption with CMOS technology
• Three-state outputs for system isolation
• High-speed operation up to 100 Mbps

Telecom Applications

• Memory mapping controllers
• Clock drivers
• Bus-oriented communications

Telecom Procurement Notes

Verify the specific suffix 'CRZ' indicates RoHS compliance and lead-free packaging as per Intersil's standard naming conventions. Confirm the package type matches the required PCB footprint. Ensure the operating voltage range aligns with the target system's 3.3V logic levels. Check for any obsolescence notices or lifecycle status updates from the manufacturer before finalizing procurement plans.

Telecom Selection Notes

Select this component when a bidirectional hex transceiver is needed for 3.3V systems. Consider the 100 Mbps speed limit for bandwidth requirements. Evaluate the TSSOP-24 package size against available board space. Compare power dissipation characteristics with alternative transceivers if thermal management is critical. Verify compatibility with the system's control logic signals.

Telecom Part Context

The HC55185 series belongs to Intersil's family of high-speed CMOS logic devices. These transceivers are commonly used in digital communication interfaces where data direction must be controlled dynamically. The HC55185 variant specifically offers six channels of bidirectional transfer, making it suitable for parallel data buses in embedded systems and industrial control applications.

Telecom Replacement Considerations

Check for direct equivalents such as the SN74LVC245A from Texas Instruments or the 74LCX245 from ON Semiconductor. Verify that substitute parts match the 3.3V supply voltage and TSSOP-24 package. Ensure the replacement maintains the same pinout configuration to avoid redesigning the PCB layout.
