Preliminary 100ELT23 5V Dual Differential PECL to TTL Translator (Preliminary) September 2002 Revised September 2002 100ELT23 5V Dual Differential PECL to TTL Translator (Preliminary) General Description The 100ELT23 is a dual differential PECL to TTL translator operating from a single +5V supply. The dual gate design of the 100ELT23 makes it ideal for applications which require the translation of a clock and a data signal. The 100 series is temperature compensated. Features s Typical propagation delay of 3.5 ns s TTL output drive: IOH = 24 mA; IOL = −3 mA s Flow through pinout s Q Output will default to a LOW with the inputs left Open s Internal pull-down resistors on inputs s Fairchild MSOP-8 package is a drop-in replacement to ON TSSOP-8 s Typical ICCH of 23 mA, ICCL of 26 mA s Meets or exceeds JEDEC specification EIA/JESD78 IC latch-up test s Moisture Sensitivity Level TBD s ESD Performance: Human Body Model > TBD Machine Model > TBD Ordering Code: Product Order Number 100ELT23M 100ELT23M8 (Preliminary) Package M08A MA08D Code KLT23 KT23 Package Description 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 8-Lead Molded Small Outline Package (MSOP), JEDEC MO-187, 3.0mm Wide Number Top Mark Devices also available in Tape and Reel.

Note 5: For IOS, the use of high-speed test apparatus and/or sample-and-hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise, prolonged shorting of a HIGH output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any sequence of parameter tests, IOS tests should be performed last. Note: Devices are designed to meet the DC specifications after thermal equilibrium has been established. Circuit is tested with air flow greater than 500LFPM maintained. www.fairchildsemi.com 2 Preliminary 100ELT23 AC Electrical Characteristics VCC = 5.0V; GND = 0.0V (Note 6)(Note 7) Symbol fMAX tJITTER tPLH, tPHL VPP tr, tf Parameter Maximum Toggle Frequency Cycle-to-Cycle Jitter Propagation Delay to Output Input Swing Output Rise Time (10% to 90%) Output Fall Time (10% to 90%) Note 6: VCC can vary ±0.25V.
