General Description
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”.

Features
■ 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
