The 'DR' suffix means it ships on tape-and-reel, ready for automated pick-and-place. ## Supply voltage and timing limits With a 4.5V to 16V supply range, the NE555DR covers the common 5V and 12V rails found in most digital and mixed-signal boards. The 100 kHz maximum frequency sets the upper bound for astable oscillator designs — above that, the output pulse width degrades. Supply current is 10 mA typical, which is the 555's own draw; the load on the output pin adds to that. For a 5V rail, the 10 mA supply current leaves headroom for a few hundred milliamps of output drive, enough to toggle a small relay or drive an LED directly. It is ROHS3 compliant (lead-free). For BOM planning, there is no need to qualify a second-source today — but if you are designing a new board, the 8-SOIC footprint is shared by many 555 variants, so a pin-compatible swap (e.g., from another TI 555 derivative) is straightforward if supply ever tightens. The 1.27 mm pin pitch is generous — easy to hand-solder or rework with a fine-tip iron. No exposed thermal pad, so the part does not need a ground-plane slug for cooling. The pin 1 identifier is a small dot on the top of the package; confirm orientation before placement. The part's low thermal mass means it will not soak heat; use a 300°C tip and short dwell to avoid lifting the pads.","metaTitle":"NE555DR Texas Instruments 555 Timer SOIC-8","metaDescription":"NE555DR — TI 555-type timer/oscillator in 8-SOIC. 100 kHz max frequency, 4.5V–16V supply, 0°C–70°C.

The pin functions are identical (GND, TRIG, OUT, RESET, CTRL, THRES, DISCH, VCC). The only difference is the package: the NE555DR is an 8-SOIC (3.90 mm wide), while the through-hole NE555 comes in an 8-DIP. If your board has an SOIC-8 footprint, the NE555DR drops in. If your board is designed for DIP, you need an adapter or a different package variant."},{"question":"Does NE555DR have a datasheet?","answer":"Yes — Texas Instruments publishes a full datasheet for the NE555DR.
