The specifc tone or tones generated are determined by inputs designated ROW 1 through ROW 4 and COLUMN 1 through COLUMN 4.The inputs are normally received from a 2-of-8 DTMF(DPST) keyboard,a Class A(SPST) keyboard,or an electronic circuit.Unlike dynamic or scanned inputs,the static inputs of the TCM5087 do not generate noise.See function table for input and output description.
single-tone enable input
This input inhibits the generation of single tones when taken low.All other chip functions remain unchanged.If the input is high or left open,single-tone operation is enabled.
transmitter switch output
This output is at high impedance when one or more of the column inputs are active and is high when all column inputs are inactive.The output is the emitter of a bipolar transistor whose is at VDD.
mute output
The mute output is high when one or more column inputs are active and is low when all column inputs are inactive.
single-tone enable input
This input inhibits the generation of single tones when taken low.All other chip functions remain unchanged.If the input is high or left open,single-tone operation is enabled.

The mute output is high when one or more column inputs are active and is low when all column inputs are inactive.
的特异性音或音调产生取决于投入指定的第1行通过第4行和第1栏通过柱4投入通常收到2的8双音多频（ DPST ）键盘， A级（ SPST ）键盘，或电子circuit.Unlike动态或扫描输入，静态投入TCM5087不会产生noise.See函数表的输入和输出的描述。
单频使能输入
这种输入抑制代单色调时采取low.All其他芯片的功能仍然unchanged.If输入高或打开，单频操作已启用。
发射机输出开关
这个输出是高阻抗当一个或一个以上的栏投入积极和高栏时，所有的投入都是inactive.The发射器输出是一个双极型晶体管，其是在VDD电压。
静音输出
静音产量高时，一个或多个列投入积极和低投入，当所有栏无效。
