ABSTRACT:
Output interface circuitry utilizable for controlling the data output of an EPROM device includes data hold circuitry that responds to the deactivation of an externally-provided output enable signal by providing a predetermined data hold time at the data output. During the predetermined data hold time, data at the EPROM's data input is guaranteed valid. Data float circuitry connected to the data hold circuitry controls the turn-off time of the data output after deactivation of the output enable signal.
