This make them particularly suitable in systems
where mixed 3V/5V logic devices need to be
interfaced.
DESCRIPTION
The 74HC241HV is an advanced high-speed
CMOS OCTAL BUS BUFFER (3-STATE)
fabricated with silicon gate C MOS technology.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.

configuration which allows all inputs to bee driven
by logic levels exceeding the supply voltage.
