BCD to Decimal Decoder

Note: xxxFN (JEDEC SOP) is not available in

Japan.

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 inputs are equipped with protection circuits against static

discharge or transient excess voltage.
