CLVC16T245MDGGEP

Overview

The CLVC16T245MDGGEP is a 16-bit dual-supply bus transceiver from Texas Instruments, designed for configurable voltage translation between mixed I/O systems. It operates with supply voltages ranging from 1.65 V to 5.5 V on both ports, eliminating the need for power supply sequencing. The device features three-state outputs and supports partial power-down applications via an Ioff function. Packaged in a 48-TSSOP format, it facilitates flexible design integration for translating signals across different voltage levels without external components.

Feature Summary

• Dual-supply architecture supporting independent A and B port voltage ranges from 1.65 V to 5.5 V
• Configurable voltage translation capabilities for mixed I/O system integration
• Ioff feature enabling safe partial power-down mode to prevent excessive current draw
• Three-state outputs allowing direct connection to bus lines

Applications

• Mixed voltage interface circuits requiring signal level translation
• Partial power-down applications in portable electronics
• Systems eliminating power supply sequencing requirements
• High-density data bus interfaces with varying logic levels

Procurement Notes

Verify the specific suffix 'MDGGEP' against official Texas Instruments documentation to confirm military or enhanced performance grade specifications. Ensure the ordering part number matches the exact package variant and temperature range required for your application. Cross-reference with the SN74LVC16T245 family datasheet for electrical characteristics and pinout compatibility before finalizing procurement.

Selection Notes

Select this component when designing systems that require bidirectional data transfer between domains operating at different voltage levels within the 1.65 V to 5.5 V range. The dual-supply capability simplifies board layout by removing the need for complex sequencing logic. Consider the Ioff feature if the system requires isolation during power-off states to minimize standby power consumption.

Part Context

This device belongs to the Texas Instruments LVC (Low Voltage CMOS) family of voltage-level translators. It is specifically engineered to bridge communication gaps between legacy 5 V logic and modern low-voltage digital systems. The 16-bit width allows for parallel data transmission, making it suitable for wide buses such as memory interfaces or microcontroller data paths.

Replacement Considerations

Public confirmed substitute part numbers include SN74LVC16T245DGGR and SN74LVCH16T245DGGR. Verify pin compatibility and electrical parameters against the original datasheet before substitution.
