Product Overview
The SN74LVC1G125 is a Texas Instruments single bus buffer gate for Signal_Chain logic interfacing. Its logic function is a single line driver with a 3-state output, and the output is disabled when the OE input is high. The device supports normal operation across a 1.65 V to 5.5 V recommended supply range, with 1.5 V specified for data retention only.
Input handling includes 5.5 V input tolerance and recommended input voltage from 0 V to 5.5 V. Recommended output voltage is 0 V to VCC. The device specifies input threshold limits across 1.65 V to 5.5 V supplies, along with output drive conditions from 4 mA at 1.65 V to 32 mA at 4.5 V.
Available package cases include SOT-23 5-pin, SC70 5-pin, SON 6-pin, DSBGA 5-pin, and X2SON 4-pin options. Pin functions identify OE and A as inputs and Y as the output. The part supports Ioff for live insertion, partial-power-down mode, and back-drive protection, with operation specified over -40°C to 125°C.
