MC100H681

The MC10/100H681 is a dual supply Hex ECL/TTL transceiver with latches in both directions. ECL controlled Direction and Chip Enable Bar pins. There are two Latch Enable pins, one for each direction.

The ECL outputs are single ended and drive 50 W. The TTL outputs are specified to source 15 mA and sink 48 mA, allowing the ability to drive highly capacitive loads. The high driving ability of the TTL outputs make the MC10/100H681 ideal for bussing applications.

The ECL output levels are standard V_OH and V_OL cutoff equal to 2.0 V (V_TT). When the ECL ports are disabled the outputs go to the V_OL cutoff level. Multiple ECL V_CCO pins are utilized to minimize switching noise.

The TTL ports have standard levels. The TTL input receivers have PNP input MC10/100H681 to significantly reduce loading. Multiple TTL power and ground pins are utilized to minimize switching noise.

The 10H version is compatible with MECL 10H ECL logic levels. The 100H version is compatible with 100K levels.
