DESCRIPTION
Bleed resistors are integrated on the output switches to eliminate the charge built up on the piezoelectric transducers.The bleed resistors are at a nominal value of 35 kΩ. 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. Data is shifted into a 6-bit shift register using an external clock. The LE latches the shift register data into the individual switch latches. A logic HI connects a switch common YX to SWX.
