DESCRIPTION  
The M54/74HCT240, HCT241 and HCT244 are  
high speed CMOS OCTAL BUS BUFFERs  
fabricated in silicon gate C2MOS technology.  
They have the same high speed performance of  
LSTTL combined with true CMOS low power  
consumption. The designer has a choise of select  
combination of inverting and non-inverting outputs,  
symmetrical G (active low output control) input, and  
complementary G and G inputs. Each control input  
governs four BUS BUFFERs.  
characteristics that are fully compatible with 54/74  
LSTTL logic families. M54/74HCT devices are  
designed to directly interface HSC2MOS systems  
with TTL and NMOS components.  
They are also plug in replacements for LSTTL  
devices giving a reduction of power consumption.  
These devices are designed to be used with 3 state  
memory address drivers, etc.  
All inputs are equipped with protection circuits  
against static discharge and transient excess  
voltage.  
This integrated circuit has input and output
