General Description
The HV232 is an 8-channel, low-charge-injection, high-voltage, analog switch integrated circuit (IC) with bleed resistors. This device can be used in applications requiring high-voltage switching controlled by low-voltage control signals, such as ultrasound imaging and printers. The bleed resistors eliminate voltage built up on capacitive loads, such as piezoelectric transducers. Input data is shifted into an 8-bit Shift register which can be retained in an 8-bit latch. To reduce any possible...
