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.
