TheHCC4511B (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.
TheHCC/HCF4511B types areBCD-to-7-segment
latch decoder drivers constructed with COS/MOS
logic and n-p-n bipolar transistor output devices on
a singlemonolithic structure. These devices combi-
ne thelow quiescentpower dissipationandhigh noi-
se immunity features of COS/MOS with n-p-n
bipolar outputtransistors capable of sourcing up to
25 mA. This capability allows the HCC/HCF4511B
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.
