The 100354 contains eight D-type edge triggered, master/ slave flip-flops with individual inputs (Dn), true outputs (Qn), a clock input (CP), an output enable pin (OEN), and a common clock enable pin (CEN). Data enters the master when CP is LOW and transfers to the slave when CP goes HIGH. When the CEN input goes HIGH it overrides all other inputs, disables the clock, and the Q outputs maintain the last state. A Q output follows its D input when the OEN pin is LOW. A HIGH on OEN holds the outputs in a cut-off state. The cutoff state is designed to be more negative than a normal ECL LOW level. This allows the output emitter-followers to turn off when the termination supply is -2.0V, presenting a high impedance to the data bus. This high impedance reduces termination power and prevents loss of low state noise margin when several loads share the bus. The 100354 outputs are designed to drive a doubly terminated 50 transmission line (25 load impedance). All inputs have 50 k pull-down resistors.Features

Note 1: The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: ESD testing conforms to MIL-STD-883, Method 3015.

Note 3: The specified limits represent the "worst case" value for the parameter. Since these values normally occur at the temperature extremes, additional noise immunity and guardbanding can be achieved by decreasing the allowable system operating ranges. Conditions for testing shown in the tables are chosen to guarantee operation under "worst case" conditions.
