Hex Buffer/Converter
High-Voltage Silicon-Gate CMOS
TECHNICAL DATA
KK4049B
The KK4049B is inverting hex buffers and feature logic-level
conversion using only one supply (voltage (VCC). The input-signal high
level (VIH) can exceed the VCC supply voltage when these devices are
used for logic-level conversions. These devices are intended for use as
CMOS to DTL/TTL converters.
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):
0.5 V min @ 5.0 V supply
1.0 V min @ 10.0 V supply
1.0 V min @ 15.0 V supply
High-to-low level conversion

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.
