| 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 Pin Shipping 2000 Units/Box 2500/Tape & Reel (c) Semiconductor Components Industries, LLC, 1999 1 December, 1999 - Rev. 6 Publication Order Number: SN74LS145/D SN74LS145 CONNECTION DIAGRAM DIP (TOP VIEW) VCC 16 P0 15 P1 14 P2 13 P3 12 Q9 11 Q8 10 Q7 9 1 Q0 2 Q1 3 Q2 4 Q3 5 Q4 6 Q5 7 8 Q6 GND LOADING (Note a) PIN NAMES P0, P1, P2, P3 Q0 - Q9 BCD Inputs Outputs HIGH 0.5 U.L.
