BCD-TO-SEVEN SEGMENT
LATCH/DECODER/DRIVER
DESCRIPTION
The UTC MC14511 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 an 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. 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.
