The TSX3704 is a micropower CMOS quad
voltage comparator which exhibits a very low
current consumption of 5 µA typical per
comparator. This device was designed as the
improvement of the TS3704: it shows a lower
current consumption, a better input offset voltage,
and an enhanced ESD tolerance. The TSX3704
is fully specified over a wide temperature range
and is proposed in automotive grade for the
TSSOP14 package. It is fully compatible with the
TS3704 CMOS comparator and is available with
similar packages. The new tiny package, QFN16
3x3, is also proposed for the TSX3704 thus
allowing even more integration on applications.

A step from 0 V to 3 V is applied on one input while the other is fixed at 1.4 V. The response time is the time interval between
the application of the input voltage step and the moment the output voltage reaches 50 % of its final value.

Input voltages
The output state is guaranteed as long as one input remains within the common mode
input voltage range (defined in the operating conditions table), and the other input remains
between -0.3 V and 16 V (meaning that one input can be driven above VCC+).
If one input voltage is beyond the range 0 V to 16 V, this input of the comparator should be
protected according to Figure 17.
If the input is lower than Vcc-, a significant current may go through the ESD diode. To
protect the circuit, this current must be limited to 10 mA by using the Rg+ or Rg- resistors.
If the input is bigger than 16 V, it has to be voltage limited. This is achieved using the D- or
D+ additional, external diodes. To protect these diodes, the current is limited using the Rg
resistor. D- and D+ diodes can be connected to another power supply with a maximum
value of 16 V. The device is designed to prevent phase reversal.

TSX3704
For unused channel
An unused comparator has to be configured to avoid unexpected additional consumption. A
simple solution is to connect the input to the power supply pins as shown in Figure 18. This
keeps the circuit in a stable state.
Figure 18: Input configuration for unused channel
6.3
Bypass capacitor
To maintain proper coupling of the power supply, it is strongly recommended to place a
0.1 μF capacitor as close as possible to the supply pins.
