ABSTRACT:
ECL bus driver circuits for multi-driver net use are provided with a disable transistor that has its emitter coupled to the emitter of the pull-down transistor of the driver so that when the disable circuit of a driver is activated, the coupled pull-down transistor is not able to sustain current flow through its collector-emitter path, and when the disable transistor is turned off, the pull-down transistor enables the drive circuit to function in its normal manner.
