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