TC7MET240AFK Inverted, 3-State Outputs

TC7MET244AFK Non-Inverted, 3-State Outputs

The TC7MET240AFK and 244AFK are advanced high speed

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.

*: output in off-state

Features

· Power down protection is provided on all inputs and outputs.

· Pin and function compatible with the 74 series (74AC/HC/F/ALS/LS etc.) 240/244 type.
