IK Semicon IW4050BD Hex buffer/converter high-voltage silicon-gate cmo Datasheet

TECHNICAL DATA
IW4050B
Hex Buffer/Converter
High-Voltage Silicon-Gate CMOS
The IW4050B is noninverting 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):
1.0 V min @ 5.0 V supply
2.0 V min @ 10.0 V supply
2.5 V min @ 15.0 V supply
• High-to-low level conversion

Maximum Ratings are those values beyond which damage to the device may occur.
Functional operation should be restricted to the Recommended Operating Conditions.

The IW4050B has high-to-low level voltage conversion capability but not low-to-high level; therefore it is
recommended that VIN ≥ VCC

The IW4050B has high-to-low level voltage conversion capability but not low-to-high level; therefore it is
recommended that VIN ≥ VCC
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.
