1 Introduction
The new MC145170-2 is pin-for-pin patible with the MC145170-1. A parison of the two parts is shown in Table 1 on page 2. The MC145170-2 is remended for new designs and has a more robust power-on reset (POR) circuit that is more responsive to momentary power supply interruptions. The two devices are actually the same chip with mask options for the POR circuit. The more robust POR circuit draws approximately 20 µA additional supply current. Note that the maximum specification of...
