High-Voltage Silicon-Gate CMOS

The

4049U is inverting hex buffers and feature logic-level

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
