74LVC162245AX4PF

Overview

The IDT74LVC162245AX4PF is a 16-bit bus transceiver from the LVC/LCX/Z series, manufactured by Integrated Device Technology. It features non-inverting bidirectional data flow with separate byte control inputs for each of its two bytes. The device operates within a supply voltage range of 1.2 V to 3.6 V and provides 3-state outputs. It utilizes a 48-pin TSSOP package (PDSO48) suitable for surface mount applications.

Feature Summary

• Supports bidirectional data transmission between two buses with independent byte control
• Provides 3-state outputs that enter high-impedance state when disabled
• Compatible with mixed 3.3 V and 5 V logic environments due to 5 V tolerant I/O

Applications

• Memory address drivers in embedded systems
• Clock drivers requiring low noise performance
• Bus transceivers in mixed-voltage digital circuits

Procurement Notes

Verify the specific suffix 'X4' against official IDT documentation to confirm if it denotes a specific tape-and-reel configuration or environmental rating. Ensure the manufacturer source is confirmed as Renesas or IDT legacy assets, as corporate ownership has changed. Cross-reference the pinout and electrical characteristics with the latest datasheet to avoid compatibility issues with newer revisions.

Selection Notes

Select this component when designing systems requiring 16-bit wide data paths with byte-level granularity. It is appropriate for applications needing interface translation between 1.2 V to 3.6 V logic levels and 5 V tolerant nodes. Consider the TSSOP-48 package constraints regarding thermal dissipation and board space compared to larger packages.

Part Context

This part belongs to the 74LVC162245 family of 16-bit bus transceivers. These devices are designed for low-voltage CMOS applications and offer high-speed operation with low power consumption. The family typically includes variants with different packaging options and temperature ranges, sharing the same core logical functionality and pinout architecture.

Replacement Considerations

Direct substitutes include the Nexperia 74LVC162245ADGG and NXP 74LVC162245A. Verify that replacement parts maintain the 30 Ω series termination resistors and 5 V tolerance specifications required by the original design.
