LC7074, 7074M
No.4789–2/17
The LC7070 Series
This section describes the differences between the different products in the LC7070 series
Usage Notes
This basic functions, including the pin functions and I/O timing, are identical in all products in the series. However,
some pin circuits and function operation details differ.
LC7070NM
…While the LC7074M is pin compatible with this product, the circuit type of the three output pins differs
as shown in table, Package and Output Driver Type Comparison. These products can be interchanged
to match the output interface. However, since the data output method following synchronization
detection differs as shown in table, Comparison of Functional Differences, care is required in writing
programs that receive, decode and process the output data for the control microprocessor.
LC7070N
……While the LC7074 is pin compatible with this product, the circuit type of the three output pins differs as
shown in table, Package and Output Driver Type Comparison. These products can be interchanged to
match the output interface. However, since the data output method following synchronization detection
differs as shown in table, Comparison of Functional Differences, care is required in writing programs
that receive, decode and process the output data for the control microprocessor.
LC7071NM
…The LC7074M is pin compatible with this product, and the pin circuit types, pin functions, and signal
timings are identical. In principle, these products are interchangeable. However, since the data output
method following synchronization detection differs as shown in table, Comparison of Functional
Differences, care is required in writing programs that receive, decode and process the output data for
the control microprocessor.
LC7073
………The LC7074 is pin compatible with this product, and the pin circuit types, pin functions, and signal
timings are identical. Furthermore, the synchronization detection method and the post-synchronization
data output method are also identical. In principle, these products are interchangeable. However, since
these products handle the block offset words E and F differently, and also handle MMBS/RDS data
differently as shown in table, Comparison of Functional Differences, care is required in writing
programs that receive, decode and process the output data for the control microprocessor.
LC7073M
……The LC7074M is pin compatible with this product, and the pin circuit types, pin functions, and signal
timings are identical. Furthermore, the synchronization detection method and the post-synchronization
data output method are also identical. In principle, these products are interchangeable. However, since
these products handle the block offset words E and F differently, and also handle MMBS/RDS data
differently as shown in table, Comparison of Functional Differences, care is required in writing
programs that receive, decode and process the output data for the control microprocessor.
