1-of-10 Decoder/Driver

Open-Collector

The SN74LS145, 1-of-10 Decoder/Driver, 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. It is designed for use as indicator/relay drivers or as

an open-collector logic circuit driver. Each of the high breakdown

output transistors will sink up to 80 mA of current. Typical power

dissipation is 35 mW. This device is fully compatible with all TTL

families.
