General Description
The TS2901 is quad independent precision voltage comparators capable of single-supply or split-supply operation.
The specifications as low as 2.0 mV make this device an excellent ground level with single-supply operation. Input
offset-voltage selection for many applications in consumer automotive, and It is designed to permit a common mode
range-to- industrial electronics.
The TS2901 is offered in SOP-14 and DIP-14 package.
Features
— Output voltage compatible with DTL, ECL, TTL,
MOS and CMOS Logic Levels
— Low input bias current -25nA
— Low input offset current ±5nA
— Low input offset voltage ±5mV(max)
— Input common mode range to ground level
— Differential input voltage range equal to power

Electrical Characteristics (Continues)
Note 1. The maximum output current may be as high as 20mA, independent of the magnitude of VCC Output short
circuits to VCC can cause excessive heating and eventual destruction.
Note 2. This magnitude of input current will only occur if the leads are driven more negative than ground or the
negative supply voltage. This is due to the input PNP collector base junction become forward biased, acting as
an input clamp diode. There is also a lateral PNP parasitic transistor action which can cause the output voltage
of the comparators to go to the VCC voltage level (or ground if overdrive is large) during the time that an input is
driven negative. This will not destroy the device when limited to the max rating and normal output states will
recover when the inputs become ground or negative supply.
Note 3. At the output switch point, VO=1.4Vdc, RS 100, 5.0VdcVCC 30Vdc, with the inputs over the full
common-mode range (0Vdc to VCC -1.5Vdc).
Note 4. The bias current flows out of the inputs due to the PNP input stage. This current is virtually constant,
independent of the output state.
Note 5. The response time specified is for a 100mV input step with 5mV overdrive For larger signals, 300ns is typical.
Note 6. Positive excursions of input voltage may exceed the power supply level. As long as one of the inputs remain
within the common-mode range, the comparator will provide the proper output state.
Note 7. The comparator will inhibit proper output state if one of the inputs is become greater than VCC, the other input
must remain within the common mode range. The low input state must not be less than -0.3volts of ground of
minus supply.
