Applications

► Medical ultrasound imaging ► NDT metal flaw detection ► Piezoelectric transducer drivers ► Optical MEMS modules General Description The Supertex HV2705 and HV2706 are low charge injection, 16-channel, high voltage analog switch integrated circuits (ICs) with bleed resistors. The devices can be used in applications requiring high voltage switching controlled by low voltage control signals, such as medical ultrasound imaging and piezoelectric transducer drivers. The bleed resistors eliminate voltage build-up on capacitive loads such as piezoelectric transducers. The HV2706 has a different pin configuration than the HV2705. Input data are shifted into a 16-bit shift register that can then be retained in a 16-bit latch. To reduce any possible clock feed-through noise, the latch enable bar should be left high until all bits are clocked in. Data are clocked in during the rising edge of the clock. Using HVCMOS technology, this device combines high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. The device is suitable for various combinations of high voltage supplies, e.g., V PP/VNN: +40V/-160V, +100V/-100V, and +160V/-40V.

Serial data is clocked in on the L to H transition of the CLK. 3. All 16 switches go to a state retaining their latched condition at the rising edge of LE. When LE is low the shift registers data flow through the latch. 4. D OUT is high when data in the shift register 15 is high. 5. Shift registers clocking has no effect on the switch states if LE is high. 6. The CLR clear input overrides all other inputs.
