Product Overview

The SN74LVC2G240 is a Texas Instruments dual 3-state buffer driver categorized under Signal_Chain. Its operating recommended supply range is 1.65 to 5.5 V, with a 1.5 V data-retention-only supply condition. Inputs are specified from 0 to 5.5 V, while outputs are specified from 0 to VCC in the high or low state and from 0 to 5.5 V in 3-state mode.

Input thresholds vary by supply range, including 0.65 × VCC minimum high-level input voltage at 1.65 V to 1.95 V and 0.7 × VCC minimum at 4.5 V to 5.5 V. Output drive ratings span -4 mA to -32 mA for high-level output current and 4 mA to 32 mA for low-level output current across the listed VCC conditions.

The device is listed in DCT SSOP-8, DCU VSSOP-8, and YZP DSBGA-8 packages, with package dimensions not provided in the extracted text. Timing data includes A-to-Y propagation delay ranges from 2.0 to 11.3 ns at 1.8 V ±0.15 V and 1.0 to 4.0 ns at 5 V ±0.5 V, supporting use in compact buffered logic and 3-state digital signal paths.
