SN74LV240ADGSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV240ADGSR is an octal inverting buffer/driver with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features a maximum propagation delay of 6.5 ns at 5 V. The device supports mixed-mode voltage operation, allowing inputs to accept voltages up to 5.5 V regardless of the VCC level. It includes Ioff support for partial power-down mode and back drive protection. The component utilizes CMOS technology and is housed in a 20-pin VSSOP (DGS) package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGSR' corresponds to the VSSOP-20 package and tape-and-reel quantity. Confirm RoHS compliance and lead finish details via the manufacturer's official Package Option Addendum. Ensure the design accounts for the specified thermal resistance values associated with this package type during PCB layout.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with inverted logic and 3-state control. It is suitable for applications needing wide voltage compatibility between 2 V and 5.5 V. Consider its low static current and latch-up performance exceeding 250 mA per JESD 17 for robust industrial or consumer electronics environments.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV240A family of octal buffers/drivers. The 'LV' designation indicates Low-Voltage CMOS technology optimized for 2 V to 5.5 V operation. The 'DGSR' suffix specifies the VSSOP surface-mount package and reel packaging format, distinguishing it from other variants like SSOP or SOIC packages.
