<P>PROBLEM TO BE SOLVED: To provide a transmitter capable of improving a through rate. <P>SOLUTION: The transmitter 1 includes: a data conversion circuit 11, a drive circuit 20, a main output buffer circuit 31 and a sub-output buffer circuit 32. The drive circuit 20 executes the following operations: when an EN signal is a non-significant value, switches SW<SB>31</SB>, SW<SB>32</SB>, SW<SB>41</SB>, SW<SB>42</SB>, SW<SB>30</SB>and SW<SB>40</SB>are turned off; when the EN signal is a significant value, the switches SW<SB>30</SB>and SW<SB>40</SB>are turned on; when a DIN signal is in an H level and the EN signal is a significant value, the switches SW<SB>31</SB>and SW<SB>42</SB>are turned on and the switches SW<SB>32</SB>and SW<SB>41</SB>are turned off; and when the DIN signal is in an L level and the EN signal is a significant value, switches SW<SB>31</SB>and SW<SB>42</SB>are turned off and the switches SW<SB>32</SB>and SW<SB>41</SB>are turned on. <P>COPYRIGHT: (C)2010,JPO&INPIT |
