WS57C71C-45CI Datasheet
WS57C71C-45CI Price When tone enable input is low, oscillator is inhibited, being allowed to low power standby mode since transistor goes to turn off state, so DO to D3 input data is ignored. However if tone enable input goes from low to high, input data is latched and tone output is enabled, and it is correspond to data input. This device is designed with 14 levels, 28 segments in each single-tone. The column tone is pre-emphasized 2dB than the row tone. WS57C71C-45CI on stock Output capacitor: a minimum bulk capacitance of 22UF, along with a O.11JF ceramic decoupling capacitor is recommended. Increasing the bulk capacitance will improve the overall transient response. The use of multiple lower value ceramic capacitors in parallel to achieve the desired bulk capacitance will not cause stability issues. Although designed for use with ceramic output capacitors, the SC1566 is extremely tolerant of output capacitor ESR values and thus will also work comfortably with tantalum output capacitors. Varistors are voltage-dependent, non-linear fesistotS whlch have symmetrical, sharp, breakdown charactoflstlcs similar to back-ta- back Zener diodes. They are desIgned for translont suppresslon In electrIcal circuits. Translents can fesult from the 8udden release of prevlously stored energy (EMP), or from extraneoua aources beyond the contfol of the circuit designer, such as Iightn{ng surges. |
