The XD4538 from Xinluda is a dual, precision monostable multivibrator (one-shot) implemented in CMOS and pin-compatible with the industry-standard 4538 / CD4538 family. Each of the two independent monostable sections offers retriggerable, resettable operation with internally latched control inputs, making the XD4538 a versatile timing element for pulse generation, debouncing, and delay applications. Output pulse width and accuracy are set by external timing components (RX and CX), and the device does not allow the timing capacitor to discharge through the timing pin on power-down, so no external protection resistor is needed in series with the timing pin.
The Xinluda XD4538 is a hard-to-find part with little to no authorized-distributor stock, which can stall production runs and legacy-board repairs. Pacific Component Xchange specializes in sourcing scarce and obsolete power-management ICs and logic components like the XD4538. We support buyers who need reliable access to allocated, end-of-life, and low-availability parts, with a focus on authenticity verification, careful inspection, and global shipping. Whether you need a small quantity for a repair or volume for a production build, our team can locate genuine inventory and provide a fast quote.
Request a quote (RFQ) today and let Pacific Component Xchange handle the hard-to-find sourcing for your XD4538 requirements.
The XD4538 is a dual, precision monostable multivibrator (one-shot) from Xinluda. It contains two independent, retriggerable and resettable monostable sections and is functionally equivalent to the industry-standard CMOS 4538 / CD4538 logic device in a DIP-16 package.
The XD4538 operates over a wide supply voltage range of 3.0V to 15V, per the Xinluda datasheet. Absolute maximum DC supply voltage is -0.5V to +18V.
Output pulse width and timing accuracy are determined by external timing components, the resistor RX and capacitor CX. The device uses linear CMOS techniques for precise pulse-width control and does not require an external protection resistor in series with the timing pin.
Yes. Both monostable sections are retriggerable and resettable with internally latched control inputs. Two trigger inputs allow rising- or falling-edge triggering, and the active-LOW reset (Clear) inputs prevent triggering while active.
Pacific Component Xchange lists the Xinluda XD4538 in a 16-pin DIP (DIP-16) package, with VDD on pin 16 and VSS on pin 8.
Yes. The XD4538 is a hard-to-find part with limited authorized-distributor availability, and Pacific Component Xchange can source it. Submit an RFQ for current availability, lead time, and pricing.
