The Xinluda XD74LS42 is a 4-line BCD-to-10-line decimal decoder built on the industry-standard 74LS42 architecture. It decodes four binary-coded-decimal (BCD) inputs into one of ten mutually exclusive active-low decimal outputs, with full input decoding that holds all outputs off for invalid (10-15) input codes. Constructed from eight inverters and ten four-input NAND gates, the XD74LS42 is a member of the low-power Schottky TTL family, offering reliable performance and broad compatibility with TTL, NMOS, and CMOS logic.
The Xinluda XD74LS42 has little to no authorized-distributor stock, making it a challenging part to source through conventional channels. Pacific Component Xchange specializes in hard-to-find and obsolete logic, power-management, and optocoupler devices. We help engineers and procurement teams secure the XD74LS42 and equivalent 74LS42 decoders when mainstream distributors show zero availability. Every order is backed by our commitment to authenticity and supply-chain verification, with global shipping to keep your production lines moving. Request a quote (RFQ) today and our sourcing team will respond with current availability, lead time, and pricing for the quantities you need.
The XD74LS42 is Xinluda's version of the standard 74LS42, a 4-line BCD-to-10-line decimal decoder built on low-power Schottky TTL technology. It converts four binary-coded-decimal inputs into one of ten mutually exclusive active-low decimal outputs.
The Xinluda XD74LS42 is supplied in a 16-pin dual in-line package (DIP-16), consistent with the rest of Xinluda's XD74LS through-hole logic family.
The device operates over a supply voltage range of 4.75 V to 5.25 V and an operating temperature range of 0 u00b0C to +70 u00b0C, typical of commercial-grade 74LS TTL logic.
Yes. The XD74LS42 follows the standard 74LS42 BCD-to-decimal decoder architecture and pinout, so it is functionally interchangeable with 74LS42 decoders from other manufacturers in equivalent DIP-16 designs. Confirm electrical parameters against your design requirements before substituting.
The Xinluda XD74LS42 has limited authorized-distributor availability. Pacific Component Xchange sources hard-to-find and obsolete logic ICs like this one. Submit an RFQ and our team will provide current availability, lead time, and pricing.
Yes. The 74LS42 provides full input decoding, ensuring all ten outputs remain off for any invalid BCD input code (decimal 10 through 15).
