SEMICONDUCTOR TECHNICAL DATA The MC10ELT/100ELT20 is a TTL to differential PECL translator. Because PECL (Positive ECL) levels are used only +5V and ground are required. The small outline 8-lead SOIC package and the single gate of the ELT20 makes it ideal for those applications where space, performance and low power are at a premium. Because the mature MOSAIC 1.5 process is used, low cost can be added to the list of features. The ELT20 is available in both ECL standards: the 10ELT is compatible with positive MECL 10H logic levels while the 100ELT is compatible with positive ECL 100K logic levels. 8 • • • • • 1.5ns Typical Propagation Delay 1 Differential PECL Outputs D SUFFIX PLASTIC SOIC PACKAGE CASE 751-05 Small Outline SOIC Package PNP TTL Inputs for Minimal Loading Flow Through Pinouts LOGIC DIAGRAM AND PINOUT ASSIGNMENT NC 1 Q TTL 2 8 VCC 7 D0 PIN DESCRIPTION PECL Q NC 3 6 4 5 NC GND PIN FUNCTION Q D VCC GND Diff PECL Outputs TTL Input +5.0V Supply Ground 1/95 Motorola, Inc. 1996 3–1 REV 2 MC10ELT20 MC100ELT20 MAXIMUM RATINGS* Symbol Parameter VCC DC Supply Voltage (Referenced to GND) VIN Input Voltage IOUT Current Applied to Output in Low Output State TA Operating Temperature Range (In Free-Air) TSTG Storage Temperature Range Value Unit 7.0 V 0 to VCC V 50 100 mA –40 to 85 °C –55 to +150 °C Continuous Surge * Maximum Ratings are those values beyond which damage to the device may occur.
