The XD74LS47 from Xinluda is a low-power Schottky TTL BCD to 7-segment decoder/driver belonging to the classic 74LS47 logic family. It accepts a 4-bit binary-coded decimal (BCD) input and produces the active-low segment drive signals required to display the decimal digits 0 through 9 on a seven-segment indicator. Its open-collector outputs are designed to drive common-anode LED displays or incandescent lamps directly, eliminating the need for external buffer transistors in many designs.
The XD74LS47 includes the full complement of control functions associated with the 74LS47 architecture: a lamp-test (LT) input for verifying all segments, a ripple-blanking input (RBI) and blanking input / ripple-blanking output (BI/RBO) for automatic leading-edge and trailing-edge zero suppression in multi-digit displays, and overall blanking control that can be used to modulate lamp intensity. Inputs and outputs are fully TTL-compatible, making the part a convenient drop-in for legacy and new TTL-based display systems.
The XD74LS47 is a niche, Xinluda-branded logic part with limited authorized-distributor coverage, which can make it difficult to secure in production quantities or for legacy maintenance needs. Pacific Component Xchange specializes in hard-to-find and obsolete power-management ICs, logic, and optocouplers, giving engineers and buyers a reliable channel when standard catalog sources fall short.
Every order is backed by our commitment to authenticity and quality, with inspection and verification processes designed to guard against counterfeit and substandard components. We offer global shipping and responsive support for both prototype and volume requirements. Request a quote (RFQ) today and our sourcing team will confirm current availability, lead time, and pricing for the XD74LS47.
The XD74LS47 is a Xinluda-branded BCD to 7-segment decoder/driver from the 74LS47 TTL logic family. It converts a 4-bit binary-coded decimal input into active-low, open-collector segment drive signals for displaying decimal digits 0 through 9 on a seven-segment LED display.
The XD74LS47 is supplied in a 16-pin dual in-line package (DIP-16).
Its open-collector, active-low outputs are intended to drive common-anode LED seven-segment displays or incandescent indicators directly.
Per the manufacturer's data, the XD74LS47 operates over a temperature range of 0 u00b0C to +70 u00b0C. As a member of the 74LS family it runs from a nominal 5 V supply.
Yes. It includes a lamp-test (LT) function plus ripple-blanking input (RBI) and blanking input / ripple-blanking output (BI/RBO) for automatic leading- and trailing-edge zero suppression in multi-digit displays.
