NCX2222

Low voltage comparator; open-drain output

10. Static characteristics

[1]

Differential input switching level is guaranteed at the minimum or maximum offset voltage, minus or plus half the maximum hysteresis

voltage.

11. Dynamic characteristics

[1]

tpd is the same as tPLZ and tPZL; tPLZ is the actual time that the output is disabled.

[2]

Input signal: 1 kHz, square wave signal with 10 ns edge rate.

Table 6.

Static characteristics

At recommended operating conditions. VCC = 1.6 V to 5.5 V, VEE = 0 V; VCM = 0.5VCC unless otherwise specified.
