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.

The ECL output levels are VOH approximately equal to –1.0 V and V
cutoff equal to –2.0 V (VTT). When the ECL ports are disabled both EIOx and
EIOxB go to the VOL cutoff level. The ECL input receivers have special
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

pins are utilized to minimize

CCO

switching noise.

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.
