SN74LVCR2245APWT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCR2245APWT is an octal bus transceiver from the Texas Instruments LVCR logic series, housed in a TSSOP-20 surface-mount package. It features non-inverting, three-state outputs and operates within a supply voltage range of 2 V to 3.6 V. The device supports TTL/CMOS input levels and provides LVTTL output levels. Key electrical specifications include a propagation delay of 7.5 ns, with low-level and high-level output currents of 12 mA and -12 mA, respectively. It functions across a temperature range of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant (TSSOP-20) and suffix (PWT) against the target design requirements. Confirm that the operating voltage range of 2 V to 3.6 V aligns with the system power rails. Ensure thermal management capabilities are sufficient for the intended ambient temperature conditions up to +125°C. Cross-reference the datasheet for moisture sensitivity level and handling precautions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with a wide operating voltage range down to 2 V is required. The LVCR series offers a balance of speed and power consumption suitable for general digital applications. Consider the TSSOP-20 package if space constraints favor surface-mount technology over through-hole options. Verify compatibility with system logic levels before integration.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCR2245A family of octal bus transceivers. It shares functional characteristics with other variants in the series, such as the SOIC-20 packaged SN74LVCR2245ADW and the VQFN-20 packaged SN74LVCR2245ARGYR. These devices provide similar electrical performance but differ in physical footprint and packaging style to accommodate various PCB layout needs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible alternatives within the same family include SN74LVCR2245ADW (SOIC-20) and SN74LVCR2245ARGYR (VQFN-20). These parts offer identical logical functionality and electrical specifications, differing primarily in package type. Ensure the replacement package fits the existing board footprint or allows for re-layout.
