MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
BCD-to-Seven-Segment Latch/
Decoder/Display Driver
High–Performance Silicon–Gate CMOS
CMOS decoder/driver. The device inputs are compatible with standard
CMOS outputs; with pullup resistors, they are compatible with LSTTL
outputs.
seven–segment decoder, and a display driver. It can be used either directly
or indirectly with seven–segment light–emitting diode (LED), incandescent,
fluorescent, gas discharge, or liquid–crystal readouts. 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.
