Description

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 cut-off state is designed to be more negative than a normalECL LOW level. This allows the output emitter-followers to turn off when the termination supply is −2.0V, presenting ahigh 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 50Ω transmission line (25Ω load impedance). Allinputs have 50 kΩ pull-down resistors.
