Compatibility with
MAX 660/MAX 665/ICL7660
The MAX860/MAX861 can be used in sockets
designed for the MAX660, MAX665, and ICL7660 with
a minimum of one wiring change. This section gives
advice on installing a MAX860/MAX861 into a socket
designed for one of the earlier devices.
The MAX660, MAX665, and ICL7660 have an OSC pin
mal operation is with OSC floating (although OSC can
DD
to enable the MAX860/MAX861
be jumpered to V
MAX861 floating.
The MAX860/MAX861 operate with FC either floating or
connected to V
DD
, OUT, or GND; each connection
defines the oscillator frequency. Thus, any of the nor-
mal MAX660, MAX665, or ICL7660 connections to pin 1
will work with the MAX860/MAX861, without modifica-
tions. Changes to the FC connection are only required
if you want to adjust the operating frequency.
