DESCRIPTION
HCF4511B is a monolithic integrated circuitfabricated in Metal Oxide Semiconductortechnology available in DIP and SOP packages. HCF4511B is a BCD to 7 segment decoder drivermade up of CMOS logic and n-p-n bipolartransistor output devices on a single monolithicstructure. This device combines the low quiescent
power dissipation and high noise immunityfeatures of CMOS with n-p-n bipolar outputtransistor capable of sourcing up to 25mA. Thiscapability allows HCF4511B to drive LEDs andother displays directly.
Lamp Test (LT), Blanking (BL), and Latch Enableor Strobe inputs are provided to test the display,shut off or intensity-modulate it, and store orstrobe a BCD code, respectively. Several differentsignals may be multiplexed and displayed whenexternal multiplexing circuitry is used.
