Description

This is 1-of-10 Decoder / Drvier Open-Collector. SN74LS145 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. http:, , onsemi.com Low Power Version of 74145 Input Clamp Diodes Limit High Speed Termination Effects GUARANTEED OPERATING RANGES Symbol VCC TA VOH IOL Parameter Supply Voltage Operating Ambient Temperature Range Output Voltage High Output Current Low Min 4.75 0 Typ 5.0 25 Max 5.25 70 15 24 Unit V °C V mA 16 LOW POWER SCHOTTKY 1 PLASTIC N SUFFIX CASE 648 16 1 SOIC D SUFFIX CASE 751B ORDERING INFORMATION Device SN74LS145N SN74LS145D Package 16 Pin DIP 16.
