Description
CD4511BMS is a 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 Intersil CMOS with n-p-n
bipolar output transistors capable of sourcing up to 25mA.
This capability allows the CD4511BMS 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.
