... DS1668 is configured to operate from a single contact closure (pushbutton) input which is integrated in the custom 6–pin package or the device can be driven from the digital source input (D). The DS1669 can be con- trolled using a single pushbutton input, dual pushbutton, or using the digital source input. 081895 2/10 Figure 3 illustrates the single pushbutton configuration of the DS1668 ...

... Additionally, the UC and DC inputs are internally debounced and require no external components for input signal conditioning. The DS1668/DS1669 are provided with two supply inputs –V and +V. The maximum voltage difference 081895 4/10 between the two supply inputs is + 8.0 volts while the minimum voltage difference is +4.5 volts. All input levels are referenced to the negative supply input, – ...
