SEMICONDUCTOR TECHNICAL DATA The MC10ELT/100ELT25 is a differential ECL to TTL translator. Because ECL levels are used a +5V, -5.2V (or -4.5V) and ground are required. The small outline 8-lead SOIC package and the single gate of the ELT25 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 VBB output allows the ELT25 to also be used in a single-ended input mode. In this mode the VBB output is tied to the IN input for a non-inverting buffer or the IN input for an inverting buffer. If used the VBB pin should be bypassed to ground via a 0.01µF capacitor. The ELT25 is available in both ECL standards: the 10ELT is compatible with MECL 10H logic levels while the 100ELT is compatible with ECL 100K logic levels. • • • • • 8 1 D SUFFIX PLASTIC SOIC PACKAGE CASE 751-05 2.6ns Typical Propagation Delay Differential ECL Inputs Small Outline SOIC Package 24mA TTL Outputs Flow Through Pinouts LOGIC DIAGRAM AND PINOUT ASSIGNMENT VEE 1 D0 TTL 2 8 VCC 7 Q0 ECL D0 3 6 NC VBB 4 5 GND PIN DESCRIPTION PIN FUNCTION D Q VCC VEE VBB GND Diff ECL Inputs TTL Output Positive Supply Negative Supply Reference Output Ground 1/95 Motorola, Inc. 1996 3–1 REV 2 MC10ELT25 MC100ELT25 MAXIMUM RATINGS* Symbol Parameter Value Unit VCC DC Supply Voltage (Referenced to GND, VEE = –5.2) 7.0 V VEE DC Supply Voltage (Referenced to GND, VCC = 5.0) –8.0 V VIN Input Voltage IOUT Current Applied to Output in Low Output State TA Operating Temperature Range (In Free-Air) TSTG Storage Temperature Range 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.
