XD555 – CMOS 555 Timer IC – Xinluda

The Xinluda XD555 is a low-power CMOS single-timer IC in a DIP-8 package, functionally interchangeable with the standard 555NE and capable of astable and monostable operation up to 2 MHz.

The XD555 from Xinluda is a single-chip CMOS timing circuit that delivers the classic 555 timer function with significantly lower power consumption. Built on a CMOS process, it is fully compatible with CMOS, TTL, and MOS logic and is functionally interchangeable with the industry-standard 555NE, making it a convenient drop-in upgrade for legacy designs that need reduced supply current and rail-to-rail output swing. Thanks to its high input impedance, the XD555 can operate at frequencies up to 2 MHz and works with smaller timing capacitors than a bipolar 555NE, enabling more precise delay and oscillation timing.

Key Features

• CMOS single-timer IC, functionally interchangeable with the 555NE
• Single-supply operation from 2 V to 15 V
• Operating frequency capability up to 2 MHz (high input impedance)
• Very low power consumption (typical 1 mW at V_DD = 5 V)
• CMOS output swings rail to rail; outputs compatible with CMOS, TTL, and MOS logic
• Supports astable (stable) oscillation and monostable timing modes
• Adjustable duty-cycle oscillation and reset function
• Operating temperature range -40 °C to +85 °C
• DIP-8 through-hole package; RoHS compliant

Applications

• Precision timing, delay, and pulse generation
• Astable and monostable multivibrator circuits
• Low-power oscillators and clock sources
• PWM and duty-cycle control
• Industrial and consumer electronics requiring 555NE-compatible timing

Why Source XD555 from Pacific Component Xchange

The Xinluda XD555 is a hard-to-find part with little to no authorized-distributor stock in North America. Pacific Component Xchange specializes in sourcing scarce and obsolete power-management ICs, timers, and optocouplers from a vetted global supply network. Every order is screened for authenticity and quality, and we ship worldwide. If you have an end-of-life design, an urgent line-down situation, or simply cannot find the XD555 through standard channels, request a quote (RFQ) from Pacific Component Xchange and our sourcing team will locate verified inventory at competitive pricing.
