Six open-drain channels for level translation and bus isolation
The Texas Instruments SN74LV07ANS is a hex (six-element) non-inverting buffer with open-drain outputs from the 74LV logic family. Each of the six channels handles one bit, and the open-drain output lets the part sink current to a pull-up voltage independent of the supply rail — useful for level-shifting a 3.3 V logic signal to a 5 V bus, or for wired-OR connections where multiple outputs share a line.
16 mA sink — enough for LEDs, relay coils, and bus lines
Each output can sink up to 16 mA when low (the high-level output is open, so no sourcing current). This sink rating drives small relays, optocoupler LEDs, or termination resistors on a bus line. Because the output is open-drain, the pull-up resistor and its voltage set the actual high-level voltage — choose a pull-up to match the downstream logic family or load requirement.
