●CD4511B types 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 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.
●The CD4511B types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (NSR suffix), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).
●These devices are similar to the type MC14511.
● 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
