74LS145

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 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. • Low Power Version of 54 / 74145 • Input Clamp Diodes Limit High Speed Termination Effects 1-OF-10 DECODER/ DRIVER OPEN-COLLECTOR LOW POWER SCHOTTKY CONNECTION DIAGRAM DIP (TOP VIEW) V CC 16 P 0 15 P 1 14 P 2 13 P 3 12 Q 9 11 Q 8 10 Q 7 J SUFFIX CERAMIC CASE 620-09 16 1 9 16 1 Q 0 2 Q 1 3 Q 2 4 Q 3 5 Q 4 6 Q 5 7 Q 6 8 GND N SUFFIX PLASTIC CASE 648-08 1 PIN NAMES P0, P1, P2, P3 Q0 to Q9 BCD Inputs Outputs (Note b) LOADING (Note a) HIGH 0.5 U.L.
