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.

CASE 776–02

The ECL output levels are V

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 V 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

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.
