NS MM74C915N

Overview

 The MM54C915/MM74C915 is a monolithic complementary MOS(CMOS) integrated circuit, constructed with N-and P-channel enhancement-mode transistors. This circuit ac-cepts 7-segment information and converts it into BCD infor-mation. The true state of the Segment inputs can be select-ed by use of the Invert/Non-Invert control pin.A logical"0"on the Invert/Non-Invert control pin selects active high true decoding at the Segment inputs.A logical"1"on the Invert/Non-Invert control pin selects active low true decoding at the Segment inputs. In addition to 4 TTL compatible BCD outputs, an Error output and Minus output are available.
