SN74LS145/D

The SN74LS145, 1-of-10 Decoder/Driver, is designed to acceptBCD inputs and provide appropriate outputs to drive 10-digitincandescent displays. All outputs remain off for all invalid binaryinput conditions. It is designed for use as indicator/relay drivers or asan open-collector logic circuit driver. Each of the high breakdownoutput transistors will sink up to 80 mA of current. Typical powerdissipation is 35 mW. This device is fully compatible with all TTLfamilies.
