TC74HC42AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC42AP, TC74HC42AF BCD to Decimal Decoder The TC74HC42A is a high speed CMOS BCD-to-DECIMAL DECODER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. A BCD code applied to the four inputs (A-D) sets a low level at one of ten decoded outputs. A illegal BCD code such as eleven thru fifteen sets all outputs high. This device can be used as 3-to-8 LINE DECODER when input D is held low. This device is useful for code conversion, address decoding, memory selection, multiplexing, or readout decoding. All...
