SN74LVC1G07DBVR

SN74LVC1G07DBVR is a single non-inverting buffer with an open-drain output in a five-pin SOT-23 (DBV) package. The selection point is what the open-drain stage enables: the output transistor only pulls down, so the pull-up resistor can tie to a rail different from the chip's own 1.65 V to 5.5 V supply, giving simple level translation for slow control signals, and several outputs can be wire-ANDed onto one shared line for wired-logic flags, alerts and enable gating. The output stage withstands voltages above the supply, so a 3.3 V-powered gate can pull a 5 V line without damage. Partial-power-down protection prevents back-drive into unpowered sections, which makes the part a safe default at domain boundaries in power-sequenced systems. Selection advice: budget the pull-up resistor deliberately — a smaller value sharpens the rising edge but burns static current whenever the line is low, and the resistor, not the chip, sets the rise time on capacitive buses. For push-pull drive at the same position, the LVC1G34 in this catalog is the direct alternative; pick the 1G07 when the shared-line or cross-rail behaviour is the actual requirement.
