Description

The TS985 is a single micropower and low voltage comparator. It can operate with a supply voltage ranging from 1.8 V to 5 V with a typical current consumption as low as 14 µA while achieving a 300 ns propagation delay. In addition, rail-to-rail inputs make it a perfect choice for low voltage applications. The 6-bump chip scale package (CSP) is a real advantage for overcoming space constraints. TS985 is specified for temperature between -40 °C to 85 °C, making it ideal for a wide range of applications. 7239,(: EXPSVRQERWWRP &63EXPS 9&& 287 9&&

1 Absolute maximum ratings

Table 1. Absolute maximum ratings (AMR)

  1. All voltage values, except differential voltage, are with respect to network ground terminal.
  2. Differential voltages are the non-inverting input termi nal with respect to the inverting input terminal.
  3. Excursions of input voltages may exceed the pow er supply level. As long as the common mode voltage

-)/2] remains within the specified range, the comparator will provide a stable output state. However, the maximum current through the ESD diodes (IF) of the input stage must strictly be observed.

  1. Short-circuits can cause exce ssive heating and destructive dissipation. Values are typical
  2. According to JEDEC standard JESD22-A114F.
  3. According to ANSI/ESD STM5.3.1.

  1. Maximum values include unavoidable ina ccuracies of the industrial tests.
  2. TP HL is measured when the output signal crosses a voltage level at 50% of VCC with the following conditions: inverting

input voltage (IN-) = VICM and non-inverting input (IN+), moving from VICM + 100mV to VICM - overdrive.

  1. TP LH is measured when the output signal crosses a voltage level at 50 % of VCC with the following conditions: inverting

input voltage (IN-) = VICM and non-inverting input (IN+), moving from VICM - 100 mV to VICM + overdrive.
