TS391H
High temperature low power single voltage comparator
Features
■ Wide single supply voltage range or dual
supplies +2 V to +36 V or
■ Very low supply current (0.2 mA) independent
±1V to ±18 V
of supply voltage (1 mW/comparator at +5 V)
■ Low input bias current: 25 nA typ.
■ Low input offset current: ±5nA typ.
■ Low input offset voltage: ±1mV typ.
■ Input common-mode voltage range includes
ground
■ Low output saturation voltage: 250 mV typ.
(I
=4mA)
o
■ Differential input voltage range equal to the
supply voltage
■ TTL, DTL, ECL, CMOS compatible outputs
Description
The TS391H is 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.
Wafer form
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.

1. Short-circuits from the output to V
maximum output current is approximately 20 mA independent of the magnitude of V
2. Short-circuits can cause excessive heating. These values are typical.
3. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
4. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins are floating.
5. Charged device model: all pins and package are charged together to the specified voltage and then
discharged directly to ground through only one pin. This is done for all pins.
