Chromosomal abnormalities in nodal and extranodal CD30+ anaplastic large cell lymphomas: Infrequent detection of the t(2;5) in extranodal lymphomas

An apparatus generates a bus-driver enable signal that enables a bus driver to couple a data signal from a sense amplifier to a data bus. A first circuit generates an equilibration pulse to equilibrate the sense amplifier, and a bus-driver enable circuit generates the bus-driver enable signal. A bus-driver disable circuit generates in response to the equilibration pulse a bus-driver disable signal for disabling the enable circuit at least until the data signal becomes valid.
