DESCRIPTION
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鈥檚 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.
