MC14513B/D
CMOS MSI
(Low–Power Complementary MOS)
The MC14513B BCD–to–seven segment latch/decoder/driver is
constructed with complementary MOS (CMOS) enhancement mode
devices and NPN bipolar output drivers in a single monolithic structure.
The circuit provides the functions of a 4–bit storage latch, an 8421
BCD–to–seven segment decoder, and has output drive capability. Lamp
test (LT), blanking (BI), and latch enable (LE) inputs are used to test the
display, to turn–off or pulse modulate the brightness of the display, and
to store a BCD code, respectively. The Ripple Blanking Input (RBI) and
Ripple Blanking Output (RBO) can be used to suppress either leading
or trailing zeroes. It can be used with seven–segment light emitting
diodes (LED), incandescent, fluorescent, gas discharge, or liquid crystal
readouts either directly or indirectly.
Applications include instrument (e.g., counter, DVM, etc.) display
driver, computer/calculator display driver, cockpit display driver, and
various clock, watch, and timer uses.

This device contains protection circuitry to protect
the inputs against damage due to high static voltages
or electric fields. However, it is advised that normal
precautions be taken to avoid application of any volt-
age higher than maximum rated voltages to this high–
impedance circuit. A destructive high current mode
may occur if V
in
and V
out
are not constrained to the
range V
SS
(V
in
or V
out
)
Due to the sourcing capability of this circuit, dam-
age can occur to the device if V
DD
is applied, and the
outputs are shorted to V
SS
and are at a logical 1 (See
Maximum Ratings).
Unused inputs must always be tied to an appropri-
ate logic voltage level (e.g., either V
SS
or V
DD
).
