The device operates from a single 3.3V supply. When /EN is LOW, the device accepts LVTTL input and provides differential LVPECL outpts referenced to the positive supply rail. When /EN is HIGH, the Q output is set in LOW state and QN output is set in HIGH state. • Flow-through pinout • –40°C to 85°C operating temperature range • ESD rating: >2000V (Human body Model) • Packaging (Pb-free & Green available): - 8-pin SOIC (W) - 8-pin MSOP (U) Block Diagram Pin Description 8-Pin (W, U) NC 1 8 VDD LVTTL/ LVCMOS Q 2 7 D LVPECL QN 3 /EN 4 6 NC N a me D e s criptio n Ty pe Pin# /EN Active LO W enab le np ut I 4* Q P EC L d ata o utp ut O 2 QN P EC L co mp lementary d ata o utp ut O 3 VDD C o nnect to 3 . 3 V P 8 D LVTTL/LVC MO S I 7 GN D C o nnect to gro und P 5 Notes: I = Input O = Output P = Power Supply Connection * = Internal 150K pull-down resistor 5 GND 1 PS8646A 10/04/04 PI90LVP10 LVTTL to Differential LVPECL Translator with Enable 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 Absolute maximum Ratings S ymbo l Parame te r Conditions M in.
