Product Summary

The SN74LS145D is a 1-of-10 decoder. It is designed to accept BCD inputs and provide appropriate outputs to drive 10-digit incandescent displays. All outputs remain off for all invalid binary input conditions. The SN74LS145D is designed for use as indicator/relay drivers or as an open-collector logic circuit driver.
