Hex open-drain buffer with wide supply range
The SN74LVC07ADBR is a hex non-inverting buffer with open-drain outputs from the 74LVC logic family. Each of the six elements handles one bit, and the open-drain output lets multiple buffers drive a common bus line through a pull-up resistor — useful for wired-OR or level-translation applications where the output voltage is set by the pull-up rail, not the supply. The low-side sink current is 24 mA per output, enough to drive an LED or a low-power relay coil directly without an external transistor.
The SSOP footprint is a standard JEDEC MO-150 variant; the 0.65 mm pin pitch breaks out cleanly on a two-layer board with 6/6 mil trace/space rules.
