TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MH240FK,TC7MH244FK
Octal Bus Buffer
TC7MH240FK Inverted, 3-State Outputs
TC7MH244FK Non-Inverted, 3-State Outputs
The TC7MH240FK and TC7MH244FK are advanced high
speed CMOS octal bus buffers fabricated with silicon gate
C
2
MOS technology.
They achieve the high speed operation similar to equivalent
bipolar schottky TTL while maintaining the CMOS low power
dissipation.
The TC7MH240FK is an inverting 3-state buffer having two
active-low output enables. The TC7MH244FK is a non-inverting
3-state buffer, and has two active-low output enables.
These devices are designed to be used with 3-state memory
address drivers, etc.
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.
