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.

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated
voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range
GND≤(VIN or VOUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC).
Unused outputs must be left open.
