BCD-to-Decimal Decoder

The TC74HC4028A is a high speed CMOS BCD-to-DECIMAL

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 high level at

one of ten decoded outputs. A illegal BCD code such as eleven

thru fifteen sets all outputs low. This device can be used as 3-to-8

LINE DECODER when input D is held high.

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.

Features

• Output drive capability: 10 LSTTL loads

• Pin and function compatible with 4028B.
