STMicroelectronics M74HC42

The M74HC42 is a high-speed CMOS BCD to decimal decoder manufactured with silicon gate t(s) SO-16 Produc Features te High speed: tpd = 14 ns (typ.) at VCC = 6 V le Low power dissipation: so ICC = 4 A (max.) at TA = 25 °C b High noise immunity: O VNIH = VNIL = 28% VCC (min.) - Symmetrical output impedance: t(s) |IOH| = IOL = 4 mA (min.) c Balanced propagation delays: tPLH tPHL u Wide operating voltage range: rod VCC (OPR) = 2 to 6 V Obsolete P Pin and function compatible with 74 series 42 C2MOS technology. This device is useful for code conversion, address decoding, memory selection, demultiplexing or readout decoding.
