CD4511BPW

The CD4511BPW is a CMOS BCD-to-7-segment LED Latch Decoder Driver constructed with CMOS logic and NPN bipolar transistor output devices on a single monolithic structure. It combines 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 25mA. This capability allows the CD4511B types to drive LED's and other displays directly. Lamp Test (LT\), Blanking (BL\) and Latch Enable or Strobe inputs are provided to test the display, shut off or intensity-modulate it and store or strobe a BCD code, respectively. Several different signals may be multiplexed and displayed when external multiplexing circuitry is used.

• Input latches for BCD Code storage
• Lamp test and blanking capability
• 100% Tested for quiescent current at 20V
• Up to 25mA High-output-sourcing capability
• 7-segment Outputs blanked for BCD input codes <gt/>1001
• Green product and no Sb/Br
