555 timer in an 8-SOIC — the classic astable/monostable workhorse
The SE555DR is a single 555-type timer/oscillator from Texas Instruments, capable of generating timing pulses up to 100 kHz.
Package and board-fit — hand-solderable SOIC
The 8-SOIC footprint is a standard JEDEC outline, so existing 555 through-hole layouts can be adapted with a small adapter board.
Active lifecycle and compliance — no end-of-life watch needed
The part is fully compliant with the latest RoHS directive, so it passes EU regulatory checks without an exemption.
