The CD74HCT4511 is a BCD-to-7 segment latch\/decoder\/driver with four address inputs (d0-d3), an active-low extinguishments (bl) input, a light detection (lt) input, and a Make latches available (le) input, which can store bcd inputs at high levels. When the coefficient is low, the latch is closed, making the output transparent to the bcd input. These devices have standard-sized output transistors, but can be purchased (at standard voh levels) up to 7.5 MA at 4.5 volts, and the hc type can be supplied up to 10 mA at 6 volts.
