74LVCHR162245APAG8

Overview

The Renesas Electronics 74LVCHR162245APAG8 is a high-speed, low-power 16-bit bus transceiver designed for asynchronous communication between two buses. It operates within a supply voltage range of 3 V to 3.6 V and features 3-state outputs. The device utilizes LVCHR logic technology, achieving a typical propagation delay of 4.8 ns. It is housed in a TSSOP-48 package suitable for surface mount installation. The component supports an operating temperature range from -40°C to +85°C and draws a typical operating supply current of 10 uA.

Feature Summary

• Provides bidirectional data transfer across 16 channels with 3-state output capability
• Optimized for high-speed asynchronous communication between system buses
• Features low power consumption characteristics inherent to the LVCHR logic family

Applications

• Asynchronous communication interfaces between system buses
• High-speed data routing in computing systems
• Memory bus interfacing applications

Procurement Notes

Verify the specific suffix 'PAG8' to confirm the TSSOP-48 package type and tape-and-reel shipping configuration. Ensure the order matches the Renesas Electronics manufacturer designation exactly. Confirm RoHS compliance status through official documentation prior to procurement. Validate that the required operating voltage range aligns with the 3 V to 3.6 V specification.

Selection Notes

Select this component when designing systems requiring 16-bit wide data paths with low skew and high speed. The LVCHR series offers improved performance over standard LVC devices. Consider the TSSOP-48 footprint constraints during PCB layout. Verify that the 3.6 V maximum supply voltage meets the target system requirements.

Part Context

This part belongs to the Renesas 74LVCHR series of bus transceivers. It shares the functional architecture with other members like the 74LVC162245 but offers enhanced speed characteristics. The device is distinct from buffer drivers such as the 74LVC162244, which lacks bidirectional control. It serves as a modern replacement for older FCT or ALVC families in high-density designs.
