MM54C42-MM74C42 is a BCD-to-Decimal decoder constructed with complementary MOS (CMOS) integrated circuit. It features a wide supply voltage range, high noise immunity, low power consumption, and medium speed operation. It is suitable for applications in automotive, alarm systems, data terminals, industrial electronics, instrumentation, remote metering, medical electronics, and computers.
This document is a datasheet for the MM54C42 and MM74C42 one-of-ten decoder integrated circuits. These are monolithic complementary MOS (CMOS) devices constructed with N- and P-channel enhancement transistors. The decoder produces a logical '0' at the output corresponding to a four-bit binary input from zero to nine, and a logical '1' at the other outputs. For binary inputs from ten to fifteen, all outputs are logical '1'.
