LM7555 CMOS Timer IC | 8-Pin | Jaycar

You know the 555. You've probably got a drawer full of them. But if your project runs on a coin cell or you need that last 10% of battery life to stretch, the LM7555 is the drop-in CMOS upgrade. Same 8-pin footprint, same astable and monostable modes, but the CMOS core draws a fraction of the current. Swap it in, keep your existing resistor-capacitor values, and your timing window stays exactly where you set it. No redesign needed. Just quieter power draw when your circuit is sitting idle

• 8-pin DIP package — direct drop-in for standard 555 timer layouts
• CMOS core delivers significantly lower quiescent current than bipolar 555
• Supports both astable (free-running) and monostable (one-shot) modes
• Suited to battery-powered timing, delay, and pulse-generation circuits
