The Xinluda XD74LS48 is a BCD-to-7-segment decoder/driver from the classic 74LS (Low-power Schottky TTL) logic family. It accepts a 4-bit binary-coded-decimal (8421) input and translates it into the corresponding seven-segment numeral pattern, making it a staple building block for digital displays. Unlike the open-collector 74LS47, the ’48 provides active-high outputs with internal pull-up resistors, allowing it to drive lamp buffers or common-cathode LED displays without external pull-up components.
The Xinluda XD74LS48 is a hard-to-find part with limited authorized-distributor availability. Pacific Component Xchange specializes in sourcing scarce, obsolete, and allocation-constrained logic and power-management ICs for engineers and procurement teams who need a reliable supply. We support legacy designs and production runs that depend on long-lifecycle components like the 74LS48.
Every order is backed by our commitment to authenticity and quality, with global shipping to keep your line running. Whether you need a handful of units for a repair or volume quantities for production, request a quote (RFQ) and our sourcing specialists will respond promptly with pricing and lead time.
The XD74LS48 is Xinluda's version of the standard 74LS48 BCD-to-7-segment decoder/driver. It converts a 4-bit binary-coded-decimal input into the seven-segment pattern needed to display the digits 0 through 9 on an LED display.
The 74LS48 (XD74LS48) has active-high outputs with internal pull-up resistors, suited to driving common-cathode LED displays or lamp buffers. The 74LS47 instead has active-low open-collector outputs for common-anode displays. They are not direct drop-in replacements for each other.
The Xinluda XD74LS48 is supplied in a 16-pin DIP (DIP-16) through-hole package and is RoHS compliant.
It operates from a 4.75 V to 5.25 V supply (5 V nominal TTL) over a commercial temperature range of 0 C to +70 C.
Yes. Like the standard 74LS48, it provides a Lamp Test (LT) input plus a Ripple-Blanking Input (RBI) and a blanking input/ripple-blanking output (BI/RBO) for leading- and trailing-zero suppression in multi-digit displays.
The XD74LS48 has limited authorized-distributor availability. Pacific Component Xchange specializes in sourcing hard-to-find and obsolete logic ICs. Submit an RFQ and our team will provide pricing, lead time, and availability.
