| HV2601 Initial Release Low Charge Injection 16-Channel High Voltage Analog Switch Features HVCMOS technology for high performance 16 Channels of high voltage analog switch 3.3V input logic level compatible 20MHz data shift clock frequency Very low quiescent power dissipation -10A Low parasitic capacitance DC to 10MHz analog signal frequency -60dB typical off-isolation at 5MHz CMOS logic circuitry for low power Excellent noise immunity Cascadable serial data register with latches Flexible operating supply voltages General Description The Supertex HV2601 is a low charge injection 16-channel high voltage analog switch integrated circuit (IC) intended for use in applications requiring high voltage switching controlled by low voltage control signals, such as medical ultrasound imaging and other piezoelectric transducer drivers. Input data is 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., VPP/VNN: +40V/-160V, +100V/-100V, and +160V/-40V.

Th 16 switches operate independently. Serial data is clocked in on the L to H transition of the CLK. 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. DOUT is high when data in the register 15 is high. Shift registers clocking has no effect on the switch states if LE is high. The CL clear input overrides all other inputs.
