Product Overview
MC74VHC244: Octal Non-inverting Bus Buffer, 3-State
For complete documentation, see the data sheet
Product Description
The MC74VHC244 is an advanced high speed CMOS octal bus buffer fabricated with silicon gate CMOS technology. The
MC74VHC244 is a noninverting 3-state buffer, and has two active-low output enables. This device is designed to be used with 3state memory address drivers, etc.
The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The
inputs tolerate voltages up to 7 V, allowing the interface of 5 V systems to 3 V systems.
