TC7MET240AFK,TC7MET244AFK
Octal Bus Buffer
TC7MET240AFK Inverted, 3-State Outputs
TC7MET244AFK Non-Inverted, 3-State Outputs
The TC7MET240AFK and 244AFK 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 TC7MET240AFK is an inverting 3-state buffer having two
active-low output enables. TC7MET244AFK 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.
The input voltage are compatible with TTL output voltage.
These devices may be used as a level converter for interfacing 3.3 V to 5 V system.
Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (
*
) pins without
regard to the supply voltage. These structure prevents device destruction due to mismatched supply and
input/output voltages such as battery back up, hot board insertion, etc.
