XD74LS248 – BCD-to-7-Segment Decoder/Driver – Xinluda

The Xinluda XD74LS248 is a 74LS-series BCD-to-seven-segment decoder/driver with active-high outputs, lamp test, and ripple-blanking control for LED display applications. Available by RFQ from Pacific Component Xchange.

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.

Key Features

• Function: BCD-to-seven-segment decoder/driver
• Output type: active-high (true) segment outputs with internal pull-up resistors for driving lamp buffers / common-cathode displays
• Seven segment outputs (a through g)
• Lamp test (LT) input for full-segment verification
• Ripple-blanking input (RBI) and blanking input / ripple-blanking output (BI/RBO) for automatic leading/trailing zero suppression and lamp-intensity control
• Logic family: low-power Schottky TTL (74LS); TTL-compatible inputs and outputs
• Recommended supply voltage: 4.75 V to 5.25 V (5 V nominal)
• Packaging: 16-pin DIP (DIP-16)

Applications

• Numeric seven-segment LED display drivers
• Digital panel meters and instrumentation readouts
• Industrial control and counter/display modules
• Consumer and appliance front-panel numeric displays
• Test and measurement equipment readouts
• Legacy TTL board repair and retrofit
