MM74C42N

Revised May 2002 MM74C42 BCD-to-Decimal Decoder General Description Features The MM74C42 one-of-ten decoder is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement transistors. This 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”. ■ Supply voltage range: 3V to 15V ■ Tenth power TTL compatible: drive 2 LPTTL loads ■ High noise immunity: 0.45 VCC (typ.) ■ Low power: 50 nW (typ.) ■ Medium speed operation: 10 MHz (typ.) with 10V VCC Applications • Automotive • Data terminals • Instrumentation • Medical electronics • Alarm systems • Industrial electronics • Remote metering • Computers Ordering Code: Order Number MM74C42N Package Number N16E Package Description 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Connection Diagram Top View © 2002 Fairchild Semiconductor Corporation DS005882 www.fairchildsemi.com MM74C42 BCD-to-Decimal Decoder October 1987 MM74C42 Schematic Diagram Truth Table Inputs www.fairchildsemi.com Outputs D C B A 0 1 2 3 4 5 6 7 8 9 0 0 0 0 0 1 1 1 1 1 1 1 1 1 0 0 0 1 1 0 1 1 1 1 1 1 1 1 0 0 1 0 1 1 0 1 1 1 1 1 1 1 0 0 1 1 1 1 1 0 1 1 1 1 1 1 0 1 0 0 1 1 1 1 0 1 1 1 1 1 0 1 0 1 1 1 1 1 1 0 1 1 1 1 0 1 1 0 1 1 1 1 1 1 0 1 1 1 0 1 1 1 1 1 1 1 1 1 1 0 1 1 1 0 0 0 1 1 1 1 1 1 1 1 0 1 1 0 0 1 1 1 1 1 1 1 1 1 1 0 1 0 1 0 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 0 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 Voltage at Any Pin (Note 1) Lead Temperature −0.3V to VCC + 0.3V Operating Temperature Range −55°C to +125°C Storage Temperature Range −65°C to +150°C 700 mW Small Outline 500 mW Operating VCC Range 260°C (Soldering, 10 seconds) Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.
