HV214

Symbol

Parameter

Value

Logic power supply voltage

4.5V to 13.2V

VPP

Positive high voltage supply

40V to VNN+ 250V

VNN

Negative high voltage supply

-40V to -210V

High-level input voltage

DD -1.5V to VDD

VIL

Low-level input voltage

0V to 1.5V

VSIG

Analog signal voltage peak to peak

VNN +10V to VPP -10V

Operating free air-temperature

0°C to 70°C

Power Up/Down Sequence:

1 Power up/down sequence is arbitrary except GND must be powered-up first and powered-down last.

SIG must be VNN ≤ VSIG ≤ VPP or floating during power up/down transistion.

3 Rise and fall times of power supplies V

DD, VPP, and VNN should not be less than 1.0msec.

Operating Conditions

Notes:

1. The eight switches operate independently.

2. Serial data is clocked in on the L→ 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

4. DOUT is high when switch 7 is on.

5. Shift register clocking has no effect on the switch states if LE is H.

6. The clear input overrides all other inputs.
