Schmitt trigger device with disable |
摘要 |
Described is a Schmitt trigger cell that can be disabled under conditions of unknown gate voltages (e.g., floating or toggling input) such that the core is isolated from the Schmitt trigger input. This is accomplished by circuitry that disables current flow through those transistors whose gate voltages are unknown during such conditions and that forces a known output onto the output terminal.
