SNJ54LS49J TI BCD-to-7-Segment Decoder | DIP | 4.75V-5.25V, 8mA Output

Product Overview

The SNJ54LS49J is a high-performance BCD-to-7-segment decoder/driver from Texas Instruments, designed for driving common-anode LED displays. It features active-low outputs and open-collector output stages capable of sinking up to 8 mA. The device accepts 4-bit BCD input and converts it to the corresponding 7-segment display code. It is manufactured using advanced low-power Schottky technology, ensuring high speed and low power consumption. The SNJ54LS49J is specified for operation over the full military temperature range of -55°C to +125°C and is available in a hermetic ceramic DIP package.
