MC14547B
The MC14547 BCD–to–seven segment 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 an 8421 BCD–to–seven segment decoder with high output drive
capability. Blanking (BI), can be used to turn off or pulse modulate the
brightness of the display. The MC14547 can drive seven–segment
light–emitting diodes (LED), incandescent, fluorescent or gas discharge
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.

* Maximum Ratings are those values beyond which damage to the device may occur.
* See Power Derating Curve Figure 1.
This device contains 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 voltage higher
than maximum rated voltages to this high-impedance circuit. A destruc-
tive high current mode may occur if Vin and Vout is not constrained to
the range VSS
≤
(Vin or Vout)
≤
VDD.
Due to the sourcing capability of this circuit, damage can occur to the
device if VDD is applied, and the outputs are shorted to VSS and are at a
logical 1 (See Maximum Ratings).
Unused inputs must always be tied to an appropriate logic voltage
level (e.g., either VSS or VDD).
