Abstract
Disclosed herein is a transmission circuit for transmitting a data signal between circuit units on a semiconductor integrated circuit through a signal wire. The data signal is transmitted by a driver circuit for precharging the signal wire to a high potential during a precharge period and discharging the signal wire to a low potential according to data to be transmitted during an evaluation period or keeping the signal wire at a high potential as floating as it is. Latch type Source-Coupled-Logic configured so that a first node and a second node used as an output terminal to the next stage are respectively charged together to a high potential during the precharge period, the second node is discharged according to a potential at the first node during the evaluation period, and the first node is discharged according to a potential on the signal wire, is used as a receiving circuit, whereby a distinction as to a high or low level of the potential on the signal wire is made with early timing provided to perform the operation of discharging the signal wire by the driver circuit.
