HLF 74LS248 BCD-to-Seven-Segment Decoder/Driver – DIP16 | High-Speed TTL Logic | 4.75V–5.25V, 0°C to +70°C | Through-Hole Package

The HLF 74LS248 is a BCD-to-seven-segment decoder/driver designed with Low-Power Schottky TTL (LS) technology, optimized for driving common-cathode LED displays. It accepts 4-bit binary-coded decimal (BCD) inputs and provides active-high decoded outputs to illuminate the corresponding numeral on the display.

The device features open-collector outputs for direct LED driving through external current-limiting resistors, along with ripple-blanking inputs and outputs for automatic leading-zero suppression and lamp test capability. Engineered for high-speed performance and low power consumption, the HLF 74LS248 ensures stable operation in digital display and counter applications.
