MC10H680, MC100H680
4−Bit Differential ECL Bus
to TTL Bus Transceiver
Description
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 W, allowing both ends of the
bus line to be terminated in the characteristic impedance of 50 W. 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
VOL 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 VCCO pins are utilized to minimize 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.
