Applications
❏ Medical ultrasound imaging ❏ Piezoelectric transducer drivers General Description These devices are low charge injection 8-channel high-voltage analog switch integrated circuits (ICs) intended for use in applications requiring high voltage switching controlled by low voltage control signals, such as ultrasound imaging and print- ers. Input data is shifted into an 8-bit shift register which can then be retained in an 8-bit latch. To reduce any possible clock feed-through noise, Latch Enable Bar (LE) should be left high until all bits are clocked in. Using HVCMOS technology, these switches combine high voltage bilateral DMOS switches and low power CMOS logic to provide efficient control of high voltage analog signals. These ICs are suitable for various combinations of high voltage supplies, e.g., V PP/VNN : +50V/–150V, or +100V/–100V.B B021706

Notes: 1. The eight switches operate independently. 2. Serial data is clocked in on the L to 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. D OUT is high when data in shift register 7 is high. 5. Shift register clocking has no effect on the switch states if LE is H. 6. The clear input overrides all other inputs.
