Input data is shifted into a 24bit shift register that can then be retained in a 24bit 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. Applications ►► ►► ►► ►► Medical ultrasound imaging Piezoelectric transducer drivers Inkjet printer heads Optical MEMS modules The device is suitable for various combinations of high voltage supplies, e.g., VPP/VNN: +40V/-160V, +100V/-100V, and +160V/-40V.

SW23 - Notes: 1. The 24 switches operate independently. 2. Serial data is clocked in on the L to H transition of the CLK. 3. All 24 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. DOUT is high when data in the register 23 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.
