SN54LS145 Datasheet | Motorola Semiconductor

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 m A of current. Typical power dissipation is 35 m W. This device is fully patible 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 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 PIN NAMES P0, P1, P2, P3 Q0 to Q9 BCD Inputs Outputs (Note b) LOADING (Note a) HIGH 0.5 U.L.
