DESCRIPTION  
The M54/74HCT157 and the M54/74HCT158 are  
high speed CMOS QUAD 2-CHANNEL MULTI-  
PLEXERs fabricated with silicon gate C2MOS tech-  
nology. They achieve the high speed operation  
similar to equivalent LSTTL while maintaining the  
CMOS low power dissipation.  
These devices consist of four 2-input digital multi-  
plexers with common select and strobe inputs. The  
HCT158 is an inverting multiplexer while the  
HCT157 is a non-inverting multiplexer. When the  
STROBE input is held High, selection of data is in-  
hibited and all the outputs become Low in the  
M74HCT157 and High in theM74HCT158. The SE-  
LECT decoding determines whether the A or B in-  
puts get routed to their corresponding Y outputs. All  
inputs are equipped with protection circuits against  
static discharge and transient excess voltage.  
M54/74HCT devices are designed to directly inter-  
face HSC2MOS systems with TTL and NMOS com-  
ponents. They are also plug in replacements for  
LSTTL devices giving a reduction of power con-  
sumption.
