A Q out- put 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 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 sev- eral loads share the bus. The 100352 outputs are designed to drive a doubly termi- nated 50 Ω transmission line (25Ω load impedance). All in- puts have 50 k Ω pull-down resistors.
