MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
Registered Hex ECL/TTL
Translator
The MC10/100H605 is a 6–bit, registered, dual supply ECL to TTL
translator. The device features differential ECL inputs for both data and
clock. The TTL outputs feature balanced 24mA sink/source capabilities for
driving transmission lines.
With its differential ECL inputs and TTL outputs the H605 device is ideally
suited for the receive function of a HPPI bus type board–to–board interface
application. The on chip registers simplify the task of synchronizing the data
between the two boards.
A VBB reference voltage is supplied for use with single–ended data or
clock. For single–ended applications the VBB output should be connected to
the “bar” inputs (Dn or CLK) and bypassed to ground via a 0.01µF capacitor.
To minimize the skew of the device differential clocks should be used.
The ECL level Master Reset pin is asynchronous and common to all
flip–flops. A “HIGH” on the Master Reset forces the Q outputs “LOW”.
The device is available in either ECL standard: the 10H device is
compatible with MECL 10H™ logic levels while the 100H device is
compatible with 100K logic levels.
