Datasheet: Serial-Input PLL Freq. Syn. With Dual-Mod.Presclr: ML145170

Source: Lansdale Semiconductor, Inc.

The new MC145170.2 is pin for pin compatible with the MC145170.1. A comparison of the two parts is shown in the available datasheet. The MC145170.2 is recommended 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 100 µA quiescent supply current has not changed.
