Cmos Level Shift Circuit With Active Pull-Up And Pull-Down
US Patent:
4980583, Dec 25, 1990
Filed:
Jan 3, 1989
Appl. No.:
7/292809
Inventors:
Paul H. Dietz - Pittsburgh PA
Assignee:
National Semiconductor Corporation - Santa Clara CA
International Classification:
H03K 17693
US Classification:
307475
Abstract:
A CMOS level shift circuit with active pull-up uses a pair of pull up transistors activated during the period when an output node needs to be rapidly pulled up. The pull up transistors are activated by the outputs of a combinatorial logic or memory circuit detecting when a change of input signal has occurred and activating the respective pull up transistor to bring the output to the proper state.
