What is the XD74LS48?

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.

What is the difference between the 74LS48 and the 74LS47?

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.

What package does the XD74LS48 come in?

The Xinluda XD74LS48 is supplied in a 16-pin DIP (DIP-16) through-hole package and is RoHS compliant.

What supply voltage and temperature range does the XD74LS48 support?

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.

Does the XD74LS48 support lamp test and zero blanking?

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.

Is the XD74LS48 hard to find, and can Pacific Component Xchange supply it?

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.

XD74LS48 – BCD-to-7-Segment Decoder/Driver – Xinluda

The Xinluda XD74LS48 is a 74LS-series BCD-to-7-segment decoder/driver in a DIP-16 package, featuring active-high outputs with internal pull-ups for driving common-cathode LED displays and lamp buffers.

Please contact us or add to quote for current pricing and availability.

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.
