XL7555 – CMOS Timer IC – Xinluda

The Xinluda XL7555 is a low-power CMOS general-purpose timer (555-type) in an SOP-8 package, operating from 2V to 18V with speeds up to 1MHz. Available for RFQ at Pacific Component Xchange.

The XL7555 from Xinluda is a low-power CMOS general-purpose timer that delivers significantly improved performance over standard SE/NE 555 bipolar timers while remaining a direct pin-for-pin replacement in most applications. Designed for both astable (oscillator) and monostable (one-shot) operation, the XL7555 supports timing intervals ranging from microseconds to hours and is ideal for precision timing, pulse generation, and modulation tasks.

Compared with traditional bipolar 555 devices, the XL7555’s CMOS process draws supply-current spikes of only a few milliamps during output transitions instead of the 300mA-400mA crowbar currents typical of bipolar parts, reducing power-supply noise and decoupling requirements. Its extremely low input current also allows the use of higher-impedance timing resistors and smaller capacitors.

Key Features

• CMOS general-purpose timer, direct replacement for SE/NE 555 in most applications
• Guaranteed supply voltage range: 2V to 18V
• High-speed operation up to 1MHz
• Very low input current: 20pA
• Temperature stability: 0.005%/°C at +25°C
• Operating temperature range: 0°C to +70°C
• High output source/sink drivers compatible with TTL/CMOS loads
• Astable and monostable operation with adjustable duty cycle
• Low supply-current spikes (a few mA) versus 300mA-400mA for bipolar 555 devices
• SOP-8 package; RoHS compliant (lead-free)

Applications

• Precision timing and sequential timing
• Pulse-width modulation (PWM)
• Pulse-position modulation (PPM)
• Pulse and waveform generation / oscillators
• Missing/leaky pulse detection

Why Source XL7555 from Pacific Component Xchange

The XL7555 is a specialty Xinluda timer with little to no authorized-distributor stock outside of a few Asia-based suppliers, which can make it difficult to source through conventional supply channels. Pacific Component Xchange specializes in hard-to-find, allocated, and end-of-life power-management ICs, timers, and optocouplers, giving engineers and buyers a reliable path to obsolete and scarce components.

Every XL7555 we supply is backed by our authenticity and inspection processes to guard against counterfeit and non-conforming parts, and we ship worldwide to support both prototype and production requirements. Because this is a request-for-quote item, pricing and lead time are tailored to your quantity and delivery needs. Contact Pacific Component Xchange today to submit an RFQ for the Xinluda XL7555 and let our sourcing team locate verified inventory for your build.
