description 3.3v and 5v power supply option 300ps typical propagation delay differential lvpecl outputs i cc max 25ma pnp lvttl inputs for minimal loading flow-through pinouts q outputs will default high with inputs open max. frequency range 800mhz available in 8-pin msop and soic package the SY100EPT22V is a dual ttl/cmos to differential pecl translator. capable of running from a 3.3 or 5v supply, the part can be used in either lvttl/lvcmos/ lvpecl or ttl/cmos/pecl systems. the device only requires a single positive supply of 3.3v or 5v - no negative supply is required. the tiny 8-pin msop package and the low skew, dual gate design of the ept22v makes it ideal for those applications where space, performance, and low power are at a premium. features 3.3v/5v dual lvttl/lvcmos-to- differential lvpecl translator pin names pin configuration/block diagram pin function q 0 , /q 0 , q 1 , /q 1 differential lvpecl outputs d 0 , d 1 lvttl inputs v cc positive supply gnd ground 1 q0 /q0 q1 /q1 8v cc d0 gnd 7 6 5 2 3 4 d1 lvpecl lvttl (available in 8-pin soic and 8-pin msop) SY100EPT22V final 1 rev.: a amendment: /1 issue date: july 2000
