That means it can sink or source current without an external pull-up resistor — a clean signal to the processor reset pin with one fewer component to place and qualify. The SOT-23-5 package (SC-74A) is a five-pin surface-mount footprint, common and easy to rework. No last-time-buy notice, no end-of-life deadline to manage.","metaTitle":"TI TPS3123J18DBVT Simple Reset/Power-On Reset IC","metaDescription":"Texas Instruments TPS3123J18DBVT simple reset/power-on reset IC.
