SN54/74LS145 1-OF-10 DECODER/DRIVER OPEN-COLLECTOR The SN54 / 74LS145, 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 1-OF-10 DECODER / DRIVER 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 OPEN-COLLECTOR current. Typical power dissipation is 35 mW. This device is fully compatible LOW POWER SCHOTTKY with all TTL families.
