Product Summary

The TC74VHC244F is an advanced high speed CMOS OCTAL BUS BUFFER fabricated with silicon gate C2MOS technology. The TC74VHC244F achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The TC74VHC244F is a non-inverting 3-state buffer, and has two active-low output enables. The TC74VHC244F is designed to be used with 3-state memory address drivers, etc.
