The HCC 4511B (extended temperature range) and

the HCF 4511B (intermediate temperature range)

are monolithic integrated circuits available in 16-le-

ad dual in-line plastic or ceramic package and pla-

stic micro package.

The HCC/HCF 4511B types are BCD-to-7-segment

latch decoder drivers constructed with COS/MOS

logic and n-p-n bipolar transistor output devices on

a single monolithic structure. These devices combi-

ne the low quiescent power dissipation and high noi-

se immunity features of COS/MOS with n-p-n

bipolar output transistors capable of sourcing up to

25 mA. This capability allows the HCC/HCF 4511B

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 signal

may be multiplexed and displayed when external

multiplexing circuitry is used.
