TRUE TTL OUTPUT TRANSLATOR-DRIVER WITH TRUE ECL TRI-STATE CONTROL |
摘要 |
The present invention provides a circuit for driving a TTL bus from an ECL circuit. The circuit of the present invention speeds up the "tri-state" to "active" transition by eliminating the need to pass the tri-state signal through a translator and buffer. A tri-state control circuit accepts true ECL input directly, thus eliminating the delay, power and density "cost" of the translator and buffer circuits. This circuit further improves the delay performance of tri-state/active transitions by restricting device saturation to low levels. File 10577-137 |
