TECHNICAL DATA
KK4028B
The KK4028B 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.
BCD-to-decimal decoding or binary-to-octal decoding
Operating Voltage Range: 3.0 to 18 V
Maximum input current of 1 µA at 18 V over full package-temperature
range; 100 nA at 18 V and 25°C
Noise margin (over full package temperature range):
1.0 V min @ 5.0 V supply
2.0 V min @ 10.0 V supply
2.5 V min @ 15.0 V supply

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.
