SN74LVCH245APWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH245APWR is an octal bus transceiver from the Texas Instruments LVC family, designed for 1.65-V to 3.6-V VCC operation. It features eight non-inverting channels with three-state outputs in a TSSOP-20 package. Key electrical parameters include a propagation delay of 7 ns, low-level output current of 24 mA, and high-level output current of -24 mA. The device supports TTL/CMOS input levels and LVTTL output levels, operating within a temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package and reel packaging configuration. Confirm RoHS compliance status and ensure the logic series matches the LVCH requirement for the target voltage domain. Cross-reference the manufacturer part number against official datasheets to validate pinout compatibility before integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring voltage translation between 1.65-V and 3.6-V supplies. The LVCH series offers optimized performance for these lower voltage ranges compared to standard LVC devices. Ensure the application requires eight bidirectional channels and can accommodate the specified propagation delay and drive current characteristics.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVCH245A series of octal bus transceivers. It shares functional similarities with other members like the SN74LVC245A but is specifically optimized for the 1.65-V to 3.6-V supply range. The 'PWR' suffix indicates surface-mount packaging in a TSSOP-20 form factor suitable for automated assembly processes.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVCH245ADWR serves as a pin-compatible alternative in SOIC-20 packaging. For broader voltage compatibility including 5-V systems, consider the SN74LVC245APWR or SN74HC245 variants, noting differences in propagation delay and drive strength.
