MC14578 Datasheet (Motorola) - Micro-Power Comparator plus Voltage Follower

MC14578, Micro-Power Comparator plus Voltage Follower

www.DataSheet4U.com Freescale Semiconductor Technical Data MC14578 Rev 2, 05/2005 CMOS Micro-Power Comparator plus Voltage Follower The MC14578 is an analog building block consisting of a very-high input impedance comparator.

The voltage follower allows monitoring the noninverting input of the comparator without loading.

Four enhancement-mode MOSFETs are also included on chip.

These FETs can be externally configured as open-drain or totem-pole outputs.

The drains have on-chip static-protectin
