HANDLING

Inputs and outputs are protected against electrostatic discharge in normal handling. However, it is good practice to take

normal precautions appropriate to handling MOS devices. See

“Data Handbook IC14 Section: Handling MOS devices”.

DC CHARACTERISTICS

VDD = 2.5 to 5.5 V; VSS =0V; Tamb = −40 to +85 °C; all voltages with respect to VSS; unless otherwise speciﬁed.

Notes

1. VIL =VSS; VIH =VDD; open drain outputs connected to VSS; all other outputs, including XTAL2, open (typical values

at 25

°C with crystal connected between XTAL1 and XTAL2).

2. VIL =VSS; VIH =VDD; RESET and T1 at VSS; INT/T0 at VDD; crystal connected between XTAL1 and XTAL2; open

drain outputs connected to VSS; all other outputs open.
