sure the sum of the currents drawn from the two out-
puts does not exceed 60mA. Connect LV as with a
standard inverter circuit (see
Pin Description).
Compatibility with
MAX660/MAX665/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
instead of

. MAX660, MAX665, and ICL7660 nor-
mal operation is with OSC floating (although OSC can
be overdriven). If OSC is floating, pin 7 (

) should
be jumpered to VDD to enable the MAX860/MAX861
permanently. Do not leave

on the MAX860/
MAX861 floating.
The MAX860/MAX861 operate with FC either floating or
connected to VDD, 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.
