Product Summary
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. The SN74LS145 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. The SN74LS145 is fully compatible with all TTL families.
Parametrics
SN74LS145 absolute maximum ratings: (1)VCC Supply Voltage: 4.75 to 5.25 V; (2)TA Operating Ambient Temperature Range: 0 to 70 °C; (3)VOH Output Voltage – High: 15 V; (4)IOL Output Current – Low: 24 mA.
