Abstract
An integrated circuit having circuitry for clamping input terminals that remain unconnected after assembly into a system. A transistor is connected to clamp the input terminal to reference potential and provide regenerative feedback to a NAND circuit forming a latch which maintains the transistor on when the input terminal would otherwise be left floating. Alternatively, when the terminal is connected to supply potential, the transistor is maintained 'off', precluding loss of power.
