systems.
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 TC7MH238FK is an advanced high speed CMOS 3-to-8
It achieves the high speed operation similar to equivalent
When the device is enabled, 3 binary select inputs (A, B and C)
When enable input G1 is held low or either G2A or G2B is held
G1, G2A and G2B inputs are provided to ease cascade
An input protection circuit ensures that 0 to 5.5 V can be
High speed: t
Low power dissipation: I
High noise immunity: V
Power down protection is provided on all inputs.
Balanced propagation delays: t
Wide operating voltage range: V
