Attorney Docket No.: 53.1139, ABSTRACT TTL CURRENT SINKING CIRCUIT WITH TRANSIENT PERFORMANCE ENHANCEMENT DURING OUTPUT TRANSITION FROM HIGH TO LOW A transient voltage difference circuit is coupled into a TTL current sinking output circuit for transient performance enhancement during transition from high to low level potential at the output. The TT1 output circuit includes a pulldown transistor element for sinking current from an output node to low potential, a base drive transistor for driving the base of a current sinking pulldown transistor element, an input base node of the base drive transistor coupled to receive input signals of high and low level potential, and a voltage clamp …

Why it's free to use
- Granted March 30, 1993. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended March 30, 2010.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
