Notes
1. LCD outputs are open-circuit; inputs at VDD or VSS; V0 = VDD; bus inactive; internal or external clock with duty cycle
50% (IDD1 only).
2. LCD outputs are open-circuit; LCD supply voltage generator is on; load current at VLCD = 20 µA.
3. Resets all logic when VDD < VPOR.
4. When the voltages are above or below the supply voltages VDD or VSS, an input current may flow; this current must
not exceed ±0.5 mA.
5. Tested on sample basis.
6. Resistance of output terminals (R1 to R32 and C1 to C60) with load current = 150 µA; VOP = VDD − VLCD = 9 V;
outputs measured one at a time; (external VLCD).
7. LCD outputs open-circuit; external VLCD.
8. Maximum value occurs at 85 °C.
15 DC CHARACTERISTICS (PCF2116K)
VDD = 2.5 to 6 V; VSS = 0 V; VLCD = VDD − 3.5 to VDD − 9 V; Tamb = −40 °C to +85 °C; unless otherwise specified.
