SN74LVTH240GQNR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH240GQNR is a 3.3-V ABT octal buffer and line driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and supports mixed-mode signal operation, allowing 5-V input and output voltages with 3.3-V VCC. The device features active bus-hold circuitry on data inputs and Ioff support for hot insertion. It is housed in a 20-pin VFBGA package (RGY) and functions as two independent 4-bit buffers with separate output-enable inputs.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operation with 5-V tolerant inputs and outputs while operating at 3.3-V VCC
• Features active bus-hold circuitry on data inputs to eliminate the need for external pullup or pulldown resistors
• Provides Ioff and power-up 3-state support to enable safe hot-insertion applications
• Includes latch-up performance exceeding 500 mA per JESD 17 and ESD protection exceeding 2000-V human-body model

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed-mode signal translation between 5-V and 3.3-V system environments
• Hot-insertion applications requiring controlled power-up and power-down states
• Bus drivers for unregulated battery operation down to 2.7 V

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix GQNR corresponds to the VFBGA package type and tape-and-reel carrier configuration. Confirm that the component meets RoHS compliance standards and matches the required moisture sensitivity level for your assembly process. Ensure the operating temperature range aligns with your design specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with 3-state control and mixed-voltage compatibility. It is suitable for applications needing high drive capability with low quiescent current. Consider the VFBGA package constraints regarding thermal management and PCB layout requirements for optimal performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH240 family of 3.3-V ABT octal buffers/drivers. It shares functional characteristics with other variants like SN74LVTH240NSR and SN74LVTH240PWR but differs in packaging. The GQNR suffix specifically denotes the VFBGA package option available in tape-and-reel format.
