7 / 16 page TLC352 LinCMOS DUAL DIFFERENTIAL COMPARATOR SLCS016A − SEPTEMBER 1985 − REVISED SEPTEMBER 2002 7 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 PARAMETER MEASUREMENT INFORMATION Response time is defined as the interval between the application of an input step function and the instant when the output reaches 50% of its maximum value. Response time, low-to-high-level output, is measured from the leading edge of the input pulse, while response time, high-to-low level output, is measured from the trailing edge of the input pulse. Response-time measurement at low input signal levels can be greatly affected by the input offset voltage. The offset voltage should be balanced by the adjustment at the inverting input (as shown in Figure 3) so that the circuit is just at the transition point. Then a low signal, for example 105-mV or 5-mV overdrive, causes the output to change state. 10% 50% 50 % Pulse Generator VDD 10 Ω 10 Turn 1 V −1 V 1 k Ω 0.1 mF CL (see Note A) 1 µF 5.1 k Ω 50 Ω Input Offset Voltage Compensation Adjustment TEST CIRCUIT tPLH 90% 10% tPHL tf tr 90% Input Overdrive Overdrive Input Low-to-High- Level Output High-to-Low- Level Output 100 mV 100 mV VOLTAGE WAVEFORMS DUT NOTE A: CL includes probe and jig capacitance.
