The XD74LS145 from Xinluda is a low-power Schottky TTL BCD-to-decimal decoder/driver belonging to the industry-standard 74LS145 logic family. It accepts a 4-bit binary-coded-decimal (BCD) input and activates one of ten mutually exclusive outputs, making it a workhorse part for decimal display, scanning, and load-switching applications. The device consists of eight inverters and ten four-input NAND gates, with the inverters arranged in pairs so that BCD input data is made available for full decoding.
Its defining feature is the set of ten high-breakdown, open-collector npn output transistors rated to sink substantial current at elevated voltage, allowing the XD74LS145 to drive incandescent lamps, relays, MOS circuitry, and other peripheral loads directly without external buffering. Full decoding of valid BCD input logic ensures that all outputs remain off for the six invalid (10 through 15) binary input combinations, simplifying fault-tolerant designs.
The XD74LS145 is a specialty and increasingly hard-to-find LS-series logic device with little to no authorized-distributor stock. Pacific Component Xchange is an independent distributor focused on obsolete, end-of-life, and difficult-to-source components. We source the XD74LS145 through trusted global supply channels, apply authenticity and quality screening, and ship worldwide to keep your production lines and repair programs running.

The XD74LS145 is a Xinluda BCD-to-decimal decoder/driver in the 74LS low-power Schottky TTL family. It decodes a 4-bit BCD input into one of ten mutually exclusive outputs and includes high-current open-collector drivers for lamps, relays, and indicator loads.
Yes. The XD74LS145 is Xinluda's implementation of the industry-standard 74LS145 / SN74LS145 BCD-to-decimal decoder/driver and shares the same function, pinout, and electrical characteristics as the generic 74LS145.
It is supplied in a 16-pin DIP (dual in-line) package, the standard through-hole format for the 74LS145 family.
Each of the ten open-collector outputs can sink up to 80 mA and withstand up to 15 V in the off state, allowing the device to drive lamps, relays, and MOS loads directly.
The XD74LS145 is a specialty LS-series logic part with limited authorized-distributor availability. Pacific Component Xchange sources it through vetted global channels and provides pricing and lead time on a request-for-quote (RFQ) basis.
Yes. Pacific Component Xchange is an independent distributor that ships hard-to-find and obsolete components worldwide. Submit an RFQ with your quantity and destination for current availability and shipping options.
