Product Summary
The 74VHC244SJX is an advanced high speed CMOS octal bus buffer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The 74VHC244SJX is a non-inverting 3-STATE buffer having two active-LOW output enables. The 74VHC244SJX is designed to be used as 3-STATE memory address drivers, clock drivers, and bus oriented transmitter/receivers. An input protection circuit ensures that 0V to 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.
