BCD-to-7-Segment LED Latch Decoder Driver (CD4511BE)

CD4511BE are BCD-to-7-segment latch decoder drivers constructed with CMOS logic and n-p-n bipolar transistor output devices on a single monolithic structure. These devices combine the low quiescent power dissipation and high noise immunity features of RCA CMOS with n-p-n bipolar output transistors capable of sourcing up to 25 MA. This capability allows the CD4511BE to drive LED’s and other displays directly.\

Features:

• High-output-sourcing capability…………up to 25 mA
• Input latches for BCD Code storage
• Lamp Test and Blanking capability
• 7-segment outputs blanked for BCD input codes > 1001
• 100% tested for quiescent current at 20 V
• Max. input current of 1 µA at 18 V, over full package-temperature range, 100 nA at 18 V and 25°C
• 5-V, 10-V, and 15-V parametric ratings

Applications:

• Driving common-cathode LED displays
• Multiplexing with common-cathode LED displays
• Driving incandescent displays
• Driving low-voltage fluorescent displays
