74LS145 datasheet


The SN54 /74LS145, 1-of-10 Decoder/Driver, is designedto accept BCD inputsand provide appropriate outputs to drive 10-digit incandescent displays.All outputs remain off forall invalid binary input conditions.

It is designedfor use as indicator/relaydrivers 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.
