Description

The MM54HC4543 MM74HC4543 BCD-to-7 segment latch decoder driver utilize advanced silicon-gate CMOS technology and can be used either as a high speed decoder or as a display driver This circuit contains a 4-bit latch BCD-to-7 segment decoder and 7 output drivers Data on the input pins flow through to the output when the LATCH ENABLE (LE) is high and is latched on the high to low transition of the LE input The PHASE input (PH) controls the polarity of the 7 segment outputs When PH is low the outpu
