SN74LVTH240PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH240PWR is a 3.3-V ABT octal buffer and line driver with 3-state outputs, manufactured by Texas Instruments in a TSSOP-20 package. It operates within a supply voltage range of 2.7 V to 3.6 V and supports an input voltage up to 5.5 V for mixed-mode signal compatibility. The device features two independent 4-bit buffers with separate output-enable inputs. Electrical characteristics include a high-level output current of -32 mA and a low-level output current of 64 mA at 3.3 V. Typical propagation delay is 2.6 ns at 3.3 V with a 50 pF load.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation allowing 5-V input tolerance with 3.3-V VCC operation
• Includes active bus-hold circuitry on data inputs to maintain valid logic states without external resistors
• Provides Ioff and power-up 3-state support to prevent damaging backflow currents during hot insertion

Buffers, Drivers, Receivers, Transceivers Applications

• Memory module data buffering
• Clock distribution and buffering
• High-density digital signal processing systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-20 package and tape-and-reel carrier configuration. Confirm that the RoHS compliance status and lead finish (NIPDAU) meet the assembly requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the system environmental specifications before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring 3.3-V logic levels with 5-V tolerant inputs. The LVTH series is suitable for applications needing higher drive strength compared to standard LV logic. Consider the TSSOP-20 package constraints regarding thermal dissipation and board space. Verify that the required propagation delay and output current capabilities fit the system timing and load requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH240 family of 3.3-V ABT octal buffers. It is functionally similar to other variants like SN74LVTH240DW or SN74LVTH240DBR but differs in packaging. The PWR suffix specifically denotes the TSSOP surface-mount package supplied in a tape-and-reel format for automated assembly processes.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include SN74LVTH240PW (tube version) and SN74LVTH240DWR (SOIC package). Verify package dimensions and moisture sensitivity levels when substituting.
