CPC7232 8-Channel High Voltage Analog Switch with Built-in Bleeder Resistors Features Description • Processed with BCDMOS on SOI (Silicon on Insulator) • Flexible High Voltage Supplies up to VPP-VNN+200V • Output Bleed Resistors Built into the Device • DC to 10MHz Analog Signal Frequency • Surface Mount Package Available • Low Quiescent Power Dissipation (< 1μA Typical) • Output Switch On-Resistance Typically 20Ω • TTL I/Os for 3.3V Interface The CPC7232 is a low charge injection 8-channel high-voltage analog switch integrated circuit (IC) for use in applications requiring high voltage switching. Bleeder resistors are incorporated into both terminals of each output switch. Control of the high voltage switching is via low voltage TTL logic level compatible inputs for direct connectivity to the system controller. Applications • Ultrasound Imaging • Printers • Industrial Controls and Measurement Because the CPC7232 is capable of switching high load voltages and has a flexible load voltage range, e.g. VPP/VNN: +40V/160V or +100V/100V, it is well suited for many medical and industrial applications such as medical ultrasound imaging, printers, and industrial measurement equipment. The bleeder resistors enable the discharge of capacitive loads, such as piezoelectric transducers, connected to the output switches of the CPC7232. Figure 1.

Functional Description The CPC7232 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 eight shift register positions, SR0 through SR7, are in the desired state. DIN: The data-in line presents data bits to the CPC7232 to be shifted through the internal shift register. 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 cleared to all 0s 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. 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: no matter what state LE is in, CL clears the latches. See “Truth Table” on page 10. Two or more CPC7232 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 CPC7232, 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 8 clock pulses per CPC7232. Setting the serial I/O device to output the most significant bit (MSB) first, results in the MSB appearing on SW7 of the last device in line after a full clocking sequence. DIN DIN CLK CLK SW0 CPC7232 CL CL LE LE DOUT: The data-out pin is the output of SR7. After eight clock pulses, the first bit of eight input data bits is shifted to SR7 and appears on DOUT. SW7 DOUT DIN CLK SW0 CPC7232 CL SW0 - SW7: The CPC7232 provides eight high-voltage SPST output switches with a typical on-resistance of 20. The two connections of each switch are not polarity-sensitive. LE SW7 DOUT 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 the data sent into the latches from the shift register: data 0 turns a switch OFF, data 1 turns a switch ON.

The eight switches operate independently. 2. Serial data is clocked in on the L? H transition CLK. 3. The switches go to a state retaining their present condition at the rising edge of LE. When LE is low the shift register data flows through the latch. 4. DOUT is high when switch 7 is on. 5. Shift register clocking has no effect on the switch states if LE is H. 6. The clear input overrides all other inputs. 2.2 Logic Timing Waveforms DN-1 DN DIN 50% LE 50% DN+1 50% 50% tWLE tSD tSU tDO DOUT tH 50% tOFF VOUT OFF (TYP) 50% 50% CLK tON 90% 10% ON CL 50% 50% tWCL 10 www.clare.com R00E CPC7232 3.
