Title: Semiconductor integrated circuit
Inventor: KUNIEDA MITSUYUKI
IPC: H03K19/0175
Filed: 1987-10-09
Abstract: PURPOSE:To operate an input circuit normally even if a power noise takes place by adopting the constitution such that a 1st gate circuit is constituted so as to bring a circuit threshold voltage to be at a TTL level and 2nd gate circuit is formed so as to bring the circuit threshold voltage to be a CMOS level. CONSTITUTION:After a chip enable signal descends and a prescribed time elapses, when an output buffer provided to an internal circuit 5 outputs an L level, a large current Iss as shown in figure flows momentarily to a power supply line, a power noise is generated due to the parasitic resistance and the parasitic inductance in the inside of the IC being parasitic in the power supply line. Since the power noise is generated on the power line of an inverter 3 having a circuit threshold value of a TTL level, the input level of the inverter 3 exceeds the circuit threshold value because the power noise is superimposed, thereby operating the inverter 3 as if an H level were inputted to the input. As s result, the output signal CE of the inverter 3 goes to an L level.

Abstract: PURPOSE:To restart transmission reception without interrupting a line by sending a tentative standby signal to an opposite party so as to allow the party to be in tentative standby state when immediate transmission reception is disabled due to any cause during transmission reception but interruption of the line is not desired. CONSTITUTION:After the line connection by dial input, a sender side sends a transmission start request signal RS1', the sender side receives a reception OK signal 2' from a receiver side, sends a picture data signal 3' and sends a signal RS4' again after the end of transmission of one picture. When the preparation is not finished as remaining data still in a buffer, the reception side decides the state by a CPU 4, a transmission tentative standby request signal 5 is sent to the sender side, the line is not interrupted and the transmission of a picture data is awaited for a prescribed time by a timer. Upon the receipt of the reception OK signal 6' at the end of the preparation of reception from the receiver side, the sender side starts the transmission of a picture data and sends an end signal 8 when the transmission is finished or no signal 6' comes till the timer expires to interrupt the line. Thus, the transmission is in standby without interruption of the line and the transmission reception is continued after the end of preparation.
