Functional Description The CPC7601 takes a serial stream of input data along with a synchronous clock signal. As the clock transits from low to high, the data at the input of each shift register is shifted through from SR(n) to SR(n+1). A high data bit, a “1,” represents an ON switch; a low data bit, a “0,” represents an OFF switch. Data is input and shifted through the internal shift register until all sixteen shift register positions, SR0 through SR15, are in the desired state. DIN: The data-in line presents data bits to be shifted through the internal shift register. The last bit into the shift register is the SW0 control bit. CLK: The clock signal's rising edge is associated only with shifting data into and through the shift register. CL: The clear line overrides all other inputs. When CL is high, the shift register is asynchronously cleared to all “0”s and all latches are set low, which causes all output switches to be turned OFF immediately. When CL is low, all output switches remain in whatever state they are in, ON or OFF, in response to CLK, latch inputs, and the LE signal. VPP and VNN: Voltage inputs to the level shifters for each switch channel that translate the voltage level of the latch output signals to an appropriate level for the voltages being switched. The high-voltage output switches are turned on and off in response to data sent into the latches from the shift register: “0” turns a switch OFF, “1” turns a switch ON. Two or more CPC7601 devices can be cascaded to form an n-switch arrangement. The DOUT pin of the first is connected to the DIN pin of the next in the series. All devices are connected to the same clock (CLK) signal. LE of all devices would normally be connected, as would CL, but this is not necessary. The first data bit applied to DIN of the CPC7601, whether it's a single device or several cascaded devices, ripples through to the last switch output in line after the application of a full clocking sequence of sixteen clock pulses. Setting the serial I/O device to output the most significant bit (MSB) first, results in the MSB appearing on SW15 of the last device in line after a full clocking sequence. LE: latch enable controls the state of the latches and thus the state of the eight switches. If LE is high, then the latches do not change states, but retain their most recent status: either ON or OFF. With LE high, input data and CLK have no effect on the state of the output switches. If LE is low, then all latch outputs and their switch states follow the inputs from the shift register. LE is overridden by CL: regardless of LE’s state, CL clears the latches. See “Truth Table” on page 9. Note that holding LE active while clocking in new data will cause the outputs to toggle with the shifting data. DIN DIN CLK CLK SW0 CPC7601 CL CL LE LE SW15 DOUT DIN CLK SW0 CPC7601 DOUT: The data-out pin is the output of SR15. After sixteen clock pulses, the first bit of sixteen shifted input data bits is output at SR15, and appears on DOUT. CL LE SW15 DOUT SW0 - SW15: The CPC7601 provides sixteen high-voltage SPST output switches with a nominal small-signal on-resistance of 25 The two connections of each switch are not polarity-sensitive.
