SEMICONDUCTOR TECHNICAL DATA  
The MC10H/100H680 is a dual supply 4–bit differential ECL bus to TTL  
bus transceiver. It is designed to allow the system designer to no longer be  
limited in bus speed associated with standard TTL busses. Using a  
differential ECL Bus will increase the frequency of operation and increase  
noise immunity.  
Both the TTL and the ECL ports are capable of driving a bus. The ECL  
outputs have the ability to drive 25 Ω, allowing both ends of the bus line to be  
terminated in the characteristic impedance of 50 Ω. The TTL outputs are  
specified to source 15 mA and sink 48 mA, allowing the ability to drive highly  
capacitive loads.

PLASTIC PACKAGE  
CASE 776–02  
The ECL output levels are V  
approximately equal to –1.0 V and V  
OH  
OL  
cutoff equal to –2.0 V (VTT). When the ECL ports are disabled both EIOx and  
EIOxB go to the V cutoff level. The ECL input receivers have special  
OL  
circuitry which detects this disabled condition, prevents oscillation, and  
forces the TTL output to the low state. The noise margin in this disabled state  
is greater than 600 mV. Multiple ECL V  
switching noise.  
pins are utilized to minimize  
CCO  
The TTL ports have standard levels. The TTL input receivers have PNP  
input devices to significantly reduce loading. Multiple TTL power and ground  
pins are utilized to minimize switching noise.  
The control pins (EDIR and ECEB) of the 10H version is compatible with  
MECL 10H ECL logic levels. The control pins of the 100H version are  
compatible with 100K levels.
