74LVCR2245ADBQRG4

Overview

The SN74LVCR2245ADBQRG4 is an octal bus transceiver manufactured by Texas Instruments, belonging to the LVC/LCX/Z logic family. It features bidirectional data transmission with three-state outputs and common direction control. The device operates within a supply voltage range of 1.65 V to 3.6 V. It utilizes a 20-pin TSSOP package (DBQ suffix) designed for surface-mount applications. Key electrical characteristics include a load capacitance of 50 pF and compliance with RoHS standards. The component supports low-voltage digital systems requiring efficient level shifting and bus isolation.

Feature Summary

• Octal bidirectional bus transceiver architecture
• Three-state output capability for bus isolation

Procurement Notes

Verify the complete part number including the G4 suffix for lead-free/RoHS compliance status. Confirm the DBQR package variant matches design requirements. Check manufacturer datasheets for specific operating conditions and thermal limits. Ensure compatibility with system voltage levels before integration.

Selection Notes

Select this component for designs requiring octal bidirectional data transfer in low-voltage environments. The common direction control simplifies interface logic compared to individual pin controls. Verify that the 50 pF load capacitance meets system trace requirements. Consider the TSSOP package dimensions for PCB layout constraints.

Part Context

This device is part of Texas Instruments' SN74LVC series, optimized for low-voltage digital applications. It serves as a standard solution for connecting microprocessors to memory or peripheral devices. The LVCR variant specifically targets cost-sensitive consumer and industrial markets while maintaining performance at reduced supply voltages.

Replacement Considerations
