Product Summary

The MM74HC244N is a non-inverting buffer and has two active low enables (1G and 2G); each enable independently controls 4 buffers. This device does not have Schmitt trigger inputs. The 3-STATE buffer utilizes advanced silicon-gate CMOS technology and are general purpose high speed non-inverting buffers. The MM74HC244N possesses high drive current outputs which enable high speed operation even when driving large bus capacitances.
