This datasheet details the features and characteristics of the MM74C42 BCD-to-Decimal Decoder, including supply voltage range, operating speed, and applications.
The MM74C42 is a monolithic complementary MOS (CMOS) integrated circuit that functions as a one-of-ten decoder. It 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'.
The device operates with a supply voltage range of 3V to 15V and is TTL compatible, capable of driving 2 LPTTL loads. It features high noise immunity and low power consumption, with typical power dissipation of 50 nW. The datasheet provides detailed electrical characteristics, including DC and AC parameters, absolute maximum ratings, and physical dimensions for the N16E 16-Lead Plastic Dual-In-Line Package (PDIP).
