LM339DR
by TI(德州仪器)
The TI LM339DR integrates four voltage comparators in one surface-mount IC, making it useful for threshold detection and signal-level comparison. Its downloadable schematic symbol maps all 14 connections needed to represent the comparator channels and shared supply pins. PCB implementation uses the SOIC-14_L8.7-W3.9-P1.27-LS6.0-BL footprint with 14 pads, complemented by a 3D model for package and clearance inspection. This conversion has been used by 2 ProtoFlow engineers in real designs, adding practical verification to the conversion and editor checks. For direct reuse in a new circuit, the LM339DR library can be opened in ProtoFlow.
