MC10ELT20, MC100ELT20 5V TTL to Differential PECL Translator Description The MC10ELT/100ELT20 is a TTL to differential PECL translator. Because PECL (Positive ECL) levels are used, only +5 V and ground are required. The small outline 8-lead package and the single gate of the ELT20 makes it ideal for those applications where space, performance, and low power are at a premium. The 100 Series contains temperature compensation. www.onsemi.com MARKING DIAGRAMS* 1 SO−8 D SUFFIX CASE 751 Features • • • • • 8 8 1.2 ns Typical Propagation Delay PNP TTL Inputs for Minimal Loading Flow Through Pinouts Operating Range: VCC = 4.75 V to 5.25 V with GND = 0 V These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant 1 1 TSSOP−8 DT SUFFIX CASE 948R = MC10 = MC100 1 KLT20 ALYW G 1 8 8 H K 8 HLT20 ALYW G 8 HT20 ALYWG G A L Y W G 1 KT20 ALYWG G = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package (Note: Microdot may be in either location) *For additional marking information, refer to Application Note AND8002/D.
