The XD74LS248 from Xinluda is a low-power Schottky (74LS) TTL BCD-to-seven-segment decoder/driver used to convert a 4-bit binary-coded-decimal input into the seven outputs required to drive a numeric seven-segment LED display. The XD74LS248 is the active-high (true) output member of the family, featuring internal pull-up resistors for driving lamp buffers or common-cathode displays, and shares the same pin assignments and logic function as the widely used ‘LS48 device.
Built-in display-management features make the XD74LS248 well suited to multi-digit numeric displays. The device provides a lamp test (LT) input to verify all segments, a ripple-blanking input (RBI) and ripple-blanking output (RBO) for automatic leading- and trailing-edge zero suppression across cascaded digits, and an overriding blanking input (BI) that shares the BI/RBO line and can be used to control lamp intensity by pulsing or to inhibit the outputs.
The XD74LS248 from Xinluda has limited authorized-distributor coverage, which can make it difficult to secure in production quantities. Pacific Component Xchange specializes in sourcing hard-to-find and end-of-life logic, power-management ICs, and optoelectronics. We help engineers and buyers locate, verify, and procure parts like the XD74LS248 with a focus on authenticity, documentation, and on-time global delivery.
Every order is supported by our quality and counterfeit-avoidance processes, and we ship worldwide to meet your build schedule. Because this is a request-for-quote item, pricing and lead time are confirmed per order. Submit an RFQ to Pacific Component Xchange today for current availability, quantity pricing, and lead time on the XD74LS248.
The XD74LS248 is a Xinluda 74LS-series (low-power Schottky TTL) BCD-to-seven-segment decoder/driver. It converts a 4-bit binary-coded-decimal input into the seven outputs needed to drive a numeric seven-segment LED display.
The 'LS248 is the active-high (true output) member of the BCD-to-seven-segment decoder family, with internal pull-up resistors, designed for driving lamp buffers or common-cathode displays. This distinguishes it from the 'LS247, which provides active-low open-collector outputs.
The Xinluda XD prefix denotes a 16-pin DIP (DIP-16) package. If you need a surface-mount option, ask Pacific Component Xchange about Xinluda's SOP equivalent when you submit your RFQ, and confirm the exact orderable package code.
It includes a lamp test (LT) input for verifying all segments, a ripple-blanking input (RBI), and a blanking input / ripple-blanking output (BI/RBO) line that enables automatic leading- and trailing-edge zero suppression across cascaded digits as well as lamp-intensity control.
The XD74LS248 is a request-for-quote (RFQ) item with limited authorized-distributor availability. Pacific Component Xchange specializes in sourcing hard-to-find logic ICs; submit an RFQ for current availability, pricing, and lead time.
Yes. The Xinluda XD74LS248 is a standard 74LS248-compatible device, sharing the same pinout, logic function, and electrical characteristics as other manufacturers' 74LS248 parts, making it a drop-in alternative.
