applied to the input pins without regard to the supply voltage.
This device can be used to interface 5 V to 3 V systems and two
supply systems such as battery back up. This circuit prevents
device destruction due to mismatched supply and input voltages.
Features
The TC74VHC240 and 244 are advanced high speed CMOS
They achieve the high speed operation similar to equivalent
The 74VHC240 is an inverting 3-state buffer having two
These devices are designed to be used with 3-state memory
