SN74LVCR2245APWE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCR2245APWE4 is an octal bus transceiver from the LVCR logic series, manufactured by Texas Instruments. It features eight bidirectional channels with three-state outputs in a TSSOP-20 package. The device operates within a supply voltage range of 2 V to 3.6 V and supports TTL/CMOS input levels while providing LVTTL output levels. Key electrical specifications include a propagation delay of 7.5 ns, a maximum power supply current of 10 uA, and output drive capabilities of 12 mA for both low and high states. It functions as a non-inverting bus switch designed for asynchronous communication between data buses.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transfer across eight independent channels with common direction control.
• Features three-state outputs that allow connection to multiple buses without signal contention.
• Designed specifically for asynchronous communication between data buses operating at low voltages.

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between data buses
• Memory and memory mapping applications
• Clock drivers and buffered oscillators

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance when sourcing. Confirm the TSSOP-20 package type matches the target PCB footprint. Ensure the voltage domain requirements align with the 2 V to 3.6 V operational range specified for this component variant.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal bus transceiver is required for low-voltage systems operating between 2 V and 3.6 V. The LVCR series is suitable for applications needing moderate speed with a 7.5 ns propagation delay. Consider the TSSOP-20 package if surface-mount space is limited compared to larger SOIC or QFN options available in the same family.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCR2245A series of octal bus transceivers. It shares core functional characteristics with other variants like the SN74LVCR2245ADW and SN74LVCR2245ARGYR, differing primarily in packaging technology such as SOIC-20 or VQFN-20. The device is part of Texas Instruments' broader portfolio of standard logic transceivers designed for general-purpose digital interfacing.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes within the same package include SN74LVCR2245ADW (SOIC-20) and SN74LVCR2245ARGYR (VQFN-20), though physical footprints differ. Verify that any replacement maintains the 2 V to 3.6 V supply range and 7.5 ns propagation delay specifications.
