SEMICONDUCTOR TECHNICAL DATA
BCD-To-Seven Segment
Latch/Decoder/Driver
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.
computer/calculator display driver, cockpit display driver, and various clock,
watch, and timer uses.
