74LVCH8T245DWRG4

Overview

The SN74LVCH8T245DWRG4 is an octal bus transceiver from the Texas Instruments LVC family, designed for dual-supply voltage level translation. It operates with a supply voltage range of 1.65V to 5.5V and features three-state outputs. The device utilizes a 24-pin SOIC package and supports bidirectional data transfer between buses operating at different logic levels. It is rated for an industrial temperature range of -40°C to +85°C.

Feature Summary

• Configurable voltage-level shifting capability for connecting systems with different power domains
• Bidirectional data transmission between two independent buses
• Three-state outputs allowing direct connection to system buses

Applications

• Mobile applications requiring low-voltage operation
• Consumer products utilizing multiple voltage domains
• Computing and industrial control systems

Procurement Notes

Verify the complete part number including the G4 suffix, which indicates lead-free status and RoHS compliance. Confirm the package type is SOIC-24 and the temperature grade is industrial (-40°C to +85°C). Ensure the datasheet matches the specific revision for electrical characteristics. Cross-reference with authorized distributors to confirm authenticity and traceability.

Selection Notes

Select this component when interfacing between 1.8V or 3.3V logic and 5V logic buses. It is suitable for designs requiring bidirectional translation with configurable direction control. Consider the propagation delay and output drive strength requirements relative to the load capacitance. Compare with the non-G4 variant if environmental compliance is not a constraint, though functionality remains identical.

Part Context

This device belongs to the SN74LVC/LVCH family of high-speed CMOS logic. The 'H' denotes enhanced performance characteristics compared to standard LVC devices. It shares functional similarities with the SN74LVC8T245 but offers optimized switching speeds. The DWR suffix specifies the 24-SOIC package with a 7.50mm width.

Replacement Considerations

SN74LVC8T245DWR is a functionally equivalent alternative within the same family.
