FET TYPE OUTPUT CIRCUIT, FET TYPE INPUT CIRCUIT AND FET TYPE INPUT/OUTPUT CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide an FET type input output circuit small in power consumption and reduced in the number of power sources. ;SOLUTION: An FET MN11 keeps an interrupt state for a delay time when an input level is subject to change till an input changes next by a delay circuit D11 and a pulse generating circuit CO-12 in a noninverting side circuit and a steady-state current via a termination resistor RT11 is not received. Thus is similar to an inverting side circuit. Even when a termination level of transmission lines L11, L12 is set in common to a high level power source or a low level power source in an input circuit CI-11, the input signal is amplified.;COPYRIGHT: (C)1998,JPO
