10 DC CHARACTERISTICS

VDD = 6.0 V; VSS =0V; fOSC = 64 kHz; Tamb = −25 to +70 °C; valid enable conditions at FDI and FDE; all voltages with

respect to VSS; unless otherwise speciﬁed.

Notes

1. For VDD <Vstb the circuit is in standby mode.

2. At VDD =VAS the automatic swell register is reset.

3. ROSC = 365 kΩ; COSC = 56 pF; FDI = FDE = VDD; all other inputs and outputs open-circuit; see Figs 8 and 9.

4. The standby supply current is measured with all inputs and outputs open-circuit, with the exception of OSC.

5. The current IIS is clamped to VDD and to VSS by two internal diodes. Correct operation is ensured with VFDI >VDD or

VFDI <VSS, provided the maximum value of IIS is not exceeded. (The input FDI has an extended HIGH and LOW

input voltage range.)
