SN74LVCR2245APW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCR2245APW is an octal bus transceiver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 3.6 V and supports TTL/CMOS input levels with LVTTL output levels. The device provides eight channels with a propagation delay of 7.5 ns and offers output currents of 12 mA for both low and high states. It is housed in a TSSOP-20 package and functions as a non-inverting standard transceiver suitable for asynchronous communication between data buses.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transfer capability between two independent buses using a single direction control signal.
• Features three-state outputs that allow connection to a common data line without electrical interference when disabled.
• Designed specifically for asynchronous communication applications requiring reliable signal integrity across varying voltage domains.

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication interfaces between microprocessors and peripheral devices
• Memory bus expansion systems requiring level translation and isolation
• General-purpose bidirectional data routing in embedded control systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'P' confirms the TSSOP-20 package variant rather than other available packages like SOIC or VQFN. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the operating temperature range meets system requirements, as industrial variants may differ from commercial grades. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver is required for 2V to 3.6V logic families. Compare against the SN74LVC4245A if 5V operation is necessary, as that variant supports higher voltage rails. Consider the TSSOP-20 footprint constraints during PCB layout. Evaluate propagation delay specifications against system timing budgets to ensure signal integrity is maintained at target clock speeds.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCR2245A series of bus transceivers. It shares functional similarities with other octal transceivers but is distinct in its specific voltage range and package configuration. The LVCR series focuses on low-voltage CMOS performance, differentiating it from standard 5V logic families while maintaining compatibility with broader system architectures.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVCR2245ADW serves as a pin-compatible alternative offering the same functionality in a SOIC-20 package. Verify package dimensions and thermal characteristics before substitution. No direct cross-series replacements are confirmed for different voltage ranges without additional circuit adjustments.
