74LVCHR162245AX4PA

Overview

The IDT74LVCHR162245AX4PA is a high-performance, low-power CMOS 16-bit dual-supply bus transceiver manufactured by Integrated Device Technology. It features 3-state outputs and is designed for applications requiring high data rates and low power consumption. The device operates as a bidirectional bus transceiver within the LVC/LCX/Z series, supporting true output logic. It utilizes a PDSO48 package configuration, suitable for dense circuit board layouts.

Feature Summary

• Dual-supply architecture enabling voltage translation between different logic families
• High-speed data rate capability for demanding digital interfaces
• Low-power CMOS technology for energy-efficient operation
• Three-state outputs to prevent bus contention during inactive states

Applications

• High-speed data routing in embedded systems
• Voltage level translation between disparate logic domains
• Memory interface buffering in consumer electronics
• Industrial control system signal isolation

Procurement Notes

Verify the manufacturer designation carefully, as IDT was acquired by Renesas Electronics. Ensure the part number suffix matches the specific package and tape-and-reel configuration required for your assembly process. Cross-reference with official Renesas or IDT documentation to confirm current production status and availability before finalizing procurement plans.

Selection Notes

Select this component when a 16-bit wide bus interface with independent supply rails is necessary. It is appropriate for designs requiring robust signal integrity at high frequencies while minimizing power dissipation. Consider the 48-pin SSOP package constraints regarding thermal management and PCB space. Validate that the input/output voltage levels align with the connected components' specifications.

Part Context

This device belongs to the 74LVC family of logic ICs, known for compatibility with various CMOS standards. It serves as a critical interface element in mixed-voltage systems. Similar parts in the lineup include the 74ALVCH162245A variants, which may offer different speed grades or packaging options. The component is widely used in portable devices and communication equipment.

Replacement Considerations

Check for direct equivalents such as the 74LVCR162245DLG4 from Texas Instruments, noting potential differences in pinout or electrical characteristics. Verify functional compatibility with other 16-bit bus transceivers from the same logic family before substitution.
