74ls47 bcd to 7 segment display datasheet


BCD to 7-Segment Decoders/Drivers General Description The DM7446A and DM7447A feature active-LOW outputs designed for driving common-anode LEDs or incandescent indicators directly. All of the circuits have full ripple-blank-ing input/output controls and a lamp test input. Segment identification and resultant displays are shown on a follow-ing ... The HEF4543B is a BCD to 7-segment latch/decoder/driver for liquid crystal and LED displays. It has four address inputs (D0 to D3), an active LOW latch enable input (LE ), an active HIGH blanking input (BL), an active HIGH phase input (PH) and seven buffered segment outputs (Qa to Qg). Jul 27, 2010 · But there must be individual 330 ohm resistors in the segment lines between the 74LS47 outputs and the display. Since you are dealing with TTL, any input that is pulled up should have a resistor between that pin and Vcc. For 74LSxx, something on the order of 10K is good. Use "74ls47" as the term in a search engine to obtain a data sheet for the IC.
