TECHNICAL DATA
IW4028B
BCD-to-Decimal Decoder
High-Voltage Silicon-Gate CMOS
The IW4028B types are BCD-to-decimal or binary-to-octal decoders
consisting of buffering on all 4 inputs, decoding-logic gates, and 10
output buffers. A BCD code applied to the four inputs, A0 to A3 results in
a high level at the selected one of 10 decimal decoded outputs. Similarly,
a 3-bit binary code applied to inputs A0 through A2 is decoded in octal
code at output 0 to7 if A3=“0”. High drive capability is provided at all
outputs to enhance dc and dynamic performance in high fan-out
applications.
