SA555DR
by TI(德州仪器)
Pulse generation and time delays are common jobs for the Texas Instruments SA555DR, a member of the familiar 555 timer family. External resistors and capacitors establish its timing behavior, making it useful for simple oscillators and one-shot circuits. This surface-mount version uses an SOIC-8 package. For schematic capture and layout, the free KiCad files supply an 8-pin symbol, the SOIC-8_L5.0-W4.0-P1.27-LS6.0-BL footprint with 8 pads and a 3D model. Practical use of the conversion includes real designs from 3 ProtoFlow engineers. The timer can be opened directly in ProtoFlow to build and place the complete timing circuit.
