Title: Key input detecting circuit
Inventor: DEURA KATSUJI
IPC: G06F3/023
Filed: 1992-01-30
Abstract: PURPOSE:To speedily recover the potential of a data line and to reduce the possibility of wrong signal generation by supplying a pulse signal to a row line which is set at an L level for a specific period right after the specific period. CONSTITUTION:An H-level signal is supplied to a scan line right after the L-level period and a three-state buffer stops the supply, thereby applying the scan line SN with the pulse signal which is held at the H level from time T1 to time T2. Consequently, the potential of the data line Dp rises quickly above the sufficient threshold voltage of a CPU in a key scan interval time of, for example, about 2musec. The rise from the L level to the H level is speedily completely, so the data line Dp is never misdetected as an L-level line during a read of respective data lines which is made successively after a next scan line SN+1 is selected, thereby eliminating the possibility of wrong signal generation.
