Overview: TC7MH257FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MH257FK
Quad 2-Channel Multiplexer (3-State)
The TC7MH257FK is an advanced high speed CMOS multiplexer fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent bipolar schottky TTL while maintaining the CMOS low power dissipation. It is posed of four independent 2-channel multiplexers with mon 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 5.5 V can be Weight: 0.02 g (typ.) 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.
