DESCRIPTION
HCF4511B is a monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology available in DIP and SOP packages.
HCF4511B is a BCD to 7 segment decoder driver
made up of CMOS logic and n-p-n bipolar
transistor output devices on a single monolithic
structure. This device combines the low quiescent
power dissipation and high noise immunity
features of CMOS with n-p-n bipolar output
transistor capable of sourcing up to 25mA. This
capability allows HCF4511B to drive LEDs 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.
