FEATURES  
DESCRIPTIO  
UltraFastTM: 7ns  
The LT®1394 is an UltraFast(7ns) comparator with comple-  
mentary outputs and latch. The input common mode range  
extends from 1.5V below the positive supply down to the  
negative supply rail. Like the LT1016, LT1116 and LT1671,  
this comparator has complementary outputs designed to  
interface directly to TTL or CMOS logic. The LT1394 may  
operate from either a single 5V supply or dual ±5V supplies.  
Low offset voltage specifications and high gain allow the  
LT1394 to be used in precision applications.

Output Latch Capability  
Available in 8-Lead MSOP and SO Packages  
The LT1394 is designed for improved speed and stability for  
a wide range of operating conditions. The output stage  
provides active drive in both directions for maximum speed  
intoTTL,CMOSorpassiveloadswithminimalcross-conduc-  
tion current. Unlike other fast comparators, the LT1394  
remains stable even for slow transitions through the active  
region,whicheliminatestheneedtospecifyaminimuminput

The LT1394 has an internal, TTL/CMOS compatible latch for  
retaining data at the outputs. The latch holds data as long as  
the LATCH pin is held high. Device parameters such as gain,  
offsetandnegativepowersupplycurrentarenotsignificantly  
affected by variations in negative supply voltage.
