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.
