Description

The TC7MH257FK is an advanced high speed CMOS multiplexer fabricated with silicon gate C2MOS technology.

TC7MH257FK achieves the high speed operation similar to equivalent bipolar schottky TTL while maintaining the CMOS low power dissipation.

TC7MH257FK is composed of four independent 2-channel multiplexers with common SELECT and OUTPUTENABLE (OE ).

If OE is set low, the outputs are held in a high-impedance state. When SELECT is set low, "A" data inputs are enabled.

Conversely, when SELECT is high, "B" data inputs are enabled.

An input protection circuit ensures that 0 to 7 V can be applied to the input pins without regard to the supply oltage. The TC7MH257FK 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
