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 ªbarº inputs (Dnor 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 ªHIGHº on the Master Reset forces the Q outputs ªLOWº.
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.
