Octal Bus Buffer
fabricated with silicon gate CMOS technology. It achieves high speed
operation similar to equivalent Bipolar Schottky TTL while maintaining
CMOS low power dissipation.
receiver. When either OE1 or OE2 is high, the terminal outputs are in the
high impedance state.
as a level converter for interfacing 3.3V to 5.0V, because it has full 5V CMOS
level output swings.
protection when voltages between 0V and 5.5V are applied, regardless of
the supply voltage. These input and output structures help prevent device
destruction caused by supply voltage – input/output voltage mismatch,
battery backup, hot insertion, etc.
