TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MH574FK
Octal D-Type Flip-Flop with 3-State Output
The TC7MH574FK is an advanced high speed CMOS octal
flip-flop with 3-state output 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.
This 8 bit D-type flip-flop is controlled by a clock input (CK)
and an output enable input (OE).
When the OE input is high, the eight outputs are in a high
impedance state.
An input protection circuit ensures that 0 to 7 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.
