General Description  
The MM74HC244 is a noninverting buffer and has two active low  
enables (1G and 2G); each enable independently controls 4 buffers.  
This device does not have Schmitt trigger inputs.

These 3STATE buffers utilize advanced silicongate CMOS  
technology and are general purpose high speed noninverting buffers.  
They possess high drive current outputs which enable high speed  
operation even when driving large bus capacitances. These circuits  
achieve speeds comparable to low power Schottky devices, while  
retaining the advantage of CMOS circuitry, i.e., high noise immunity,  
and low power consumption. All three devices have a fanout of  
15 LSTTL equivalent inputs.
