HM311

LOW POWER SINGLE VOLTAGE

COMPARATOR



DESCRIPTION

The HM311/A/B/C consists of a low power voltage

comparator designed specifically to operate from a single supply

over a wide range of voltages. Operation from split power supplies is

also possible.

This comparator also has a unique characteristic in that the input

common-mode voltage range includes ground even though operated

from a single power supply voltage.



FEATURES

* Wide single supply voltage range or dual supplies +2V~+36V or

±1V~±18V

* Very low supply current (0.2mA) independent of supply voltage

(1mW /comparator at +5V)

* Low input bias current: 25nA typ.

* Low input offset current: ±5nA typ.

* Low input offset voltage: ±1mV typ

* Input common-mode voltage range includes ground.

* Low output saturation voltage: 250mV typ.(I_OUT=4mA).

* Differential input voltage range equal to the supply voltage.

* TTL, DTL, ECL, CMOS Compatible outputs.

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.

2. Short-circuit from the output to V_CCcan cause excessive heating and eventual destruction. The maximum

output current is approximately 20mA, independent of the magnitude of V_CC

Notes: 1. At output switch point, Vo=1.4V, R_S=0Ω with V_CCfrom 5V ~ 30V and over the full input common-mode

range (0V ~ V_CC1.5V).

2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially

constant, independent of the state of the output, so no loading charge exists on the reference or input

lines.

3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by

more than 0.3V.The upper end of the common-mode voltage range is V_CC+ -1.5V,but either or both inputs

can go to +30V without damage.

4. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage

remains within the common-mode range the comparator will provide a proper output state.

The low input voltage state must not be less than -0.3V (or 0.3V below the negative power supply, if used).

5. The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals

300ns can be obtained.
