SEMICONDUCTOR TECHNICAL DATA 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 Ω. 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 device ideal for bussing applications. The ECL output levels are standard VOH and VOL cutoff equal to –2.0 V (VTT). When the ECL ports are disabled the outputs go to the VOL cutoff level. 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 10H version is compatible with MECL 10H ECL logic levels. The 100H version is compatible with 100K levels.
