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 TC7MH257FK is an advanced high speed CMOS
It achieves the high speed operation similar to equivalent
It is composed of four independent 2-channel multiplexers with
If OE is set low, the outputs are held in a high-impedance state.
Conversely, when SELECT is high, “B” data inputs are
