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 C
2
MOS technology.
It achieves the high speed operation similar to equivalent
bipolar schottky TTL while maintaining the CMOS low power
dissipation.
It 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 5.5 V can be
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.
