1 The MC0ELT/00ELT20 is a TTL to differential PECL translator. Because PECL (Positive ECL) levels are used, only +5 V and ground are required. The small outline -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 00 Series contains temperature compensation..2 ns Typical Propagation elay PNP TTL Inputs for Minimal Loading Flow Through Pinouts ES Protection: >4 KV HBM, >200 V MM Operating Range: V CC = 4.75 V to 5.25 V with GN= 0 V No Internal Input Pulldown Resistors Meets or Exceeds JEEC Spec EIA/JES7 IC Latchup Test Moisture Sensitivity Level For Additional Information, see Application Note AN003/ Flammability Rating: UL 94 code V /, Oxygen Index 2 to 34 Transistor Count = 5 devices LOGIC IAGRAM AN PINOUT ASSIGNMENT NC Q 2 TTL 7 V CC SO SUFFIX CASE 75 TSSOP T SUFFIX CASE 94R H = MC0 K = MC00 A = Assembly Location MARKING IAGRAMS* HLT20 ALYW HT20 ALYW KLT20 ALYW L = Wafer Lot Y = Year W = Work Week *For additional information, see Application Note AN002/ KT20 ALYW Q NC PECL NC GN PIN ESCRIPTION PIN FUNCTION Q, Q PECL ifferential Outputs* TTL Input V CC Positive Supply GN Ground NC No Connect ORERING INFORMATION evice Package Shipping MC0ELT20 SO 9 Units/Rail MC0ELT20R2 SO 2500 Tape & Reel MC00ELT20 SO 9 Units/Rail MC00ELT20R2 SO 2500 Tape & Reel MC0ELT20T TSSOP 9 Units/Rail MC0ELT20TR2 TSSOP 2500 Tape & Reel MC00ELT20T TSSOP 9 Units/Rail MC00ELT20TR2 TSSOP 2500 Tape & Reel * Output state undetermined when inputs are open.
