H393P

LOW POWER L OW OFFSET VOLTAGE COMPARATORS

Description

The H393P series consists of two independent precision voltage
comparators designed specifically to operate from a single power supply
over a wide range of voltages, the input common mode voltage range
includes ground. Owing to adoption of clamp circuitry in input pins, mis­operation is prevented by negative input.

Features

Wide power supply voltage range

•

Single power supply.............................................................................................................. 2 V to 30 V

Dual power supplies........................................................................................................ ± 1 V to ± 15 V

Wide input common-mode voltage range.................................................................... 0 V to (Vcc-1.5) V

•

Low input bias current............................................................................................................. 25 nA typ.

•

High sink current capability because of open collector otput 40mA min.

Power Supply Voltage VCC 36 V
Differential Input Voltage VID 36 V
Common-Mode Input Voltage VI -5 to 36 V
Output Short Current to GND - Infinite* ­Power Dissipation PD

Operating Temperature Ta -20 to +75
Storage Temperature Tstg -55 to +125

*: This value is specified with respect to the short circuit from output to GND. However, short circuit from the output to VCC

cause device destruction.

Note: Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded. Functional operation should

be restricted to the conditions as detailed in the operational sections of this data sheet. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.

Notes:
*1: Iin is measued when Vi≥0 and direction of the input current flows from IC. When negative voltage is applied to input pin, the

pin is equivalently connected the GND through a 1kΩ of resistor.
When low voltage below than –5V is applied, please connect a resistor serially to input pin in order to prevent the high
current flow.

*2: Positive input voltage may exceed the power supply voltage. As long as the other voltage remains in the common-mode

input voltage range, the comparator will provide a proper output state.
When Vcc=5V, your are requested to use Vin below 25V.
