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 V
CCO
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.
• Separate Latch Enable Controls for each Direction
• ECL Single Ended 50 Ω I/O Port
• High Drive TTL I/O Ports
• Extra TTL and ECL Power/Ground Pins to Minimize
Switching Noise
• Dual Supply
• Direction and Chip Enable Control Pins
