_______________General Description

The MAX364/MAX365 are precision, quad, single-pole

single-throw (SPST) analog switches.  The MAX364 has

four normally closed (NC), and the MAX365 has four

normally open (NO) switches.  Both parts offer low-

channel on resistance (less than 85

), guaranteed to

match within 2

between channels and to remain flat

over the analog signal range (

9

max).  Both parts

also offer low leakage (less than 500pA at +25°C and

less than 4nA at +85°C) and fast switching (turn-on

time less than 250ns and turn-off time less than 170ns).

The MAX364/MAX365 are fabricated with Maxim’s new

improved 44V silicon-gate process.  Design improve-

ments guarantee extremely low charge injection

(10pC),  low power consumption (35µW), and electro-

static discharge (ESD) greater than 2000V.  The 44V

maximum breakdown voltage allows rail-to-rail analog

signal handling capability.

These monolithic switches operate with a single positive

supply (+10V to +30V) or with split supplies (±4.5V to

±20V) while retaining CMOS-logic input compatibility

and fast switching.  CMOS inputs provide reduced

input loading.

__________Applications Information

Application Hints

1.  Switches are open when power is off.

2.  IN_, COM_, NO_, and NC_ should not exceed V+ or

V-, even with the power off.

3.  Switch leakage is from each analog switch terminal

to V+ or V-, not to the other switch terminal.

Operation with Supply Voltages

Other than ±15VO

The main limitation of supply voltages other than ±15V is

reduction in the analog signal range.  The MAX364/MAX365

switches operate with ±5V to ±20V bipolar supplies.  The

Typical Operating Characteristics graphs show typical on

resistance for ±15V, ±10V, and ±5V supplies.  Switching

times increase by a factor of two or more for ±5V opera-

tion.  The MAX364/MAX365 operate from unipolar sup-

plies of +10V to +24V.  Both parts can be powered from a

single +10V to +24V supply, as well as from unbalanced

supplies, such as +24V and -5V.  Connect V- to 0V when

operating with a single supply.  VL must be connected to

+5V to be TTL compatible or to V+ for CMOS logic input

levels.

Overvoltage Protection

Proper power-supply sequencing is recommended for

all CMOS devices.  It is important not to exceed the

absolute maximum ratings, because stresses beyond

those listed may cause permanent damage to the

devices.  Always sequence V+ on first, followed by VL,

V-, and logic inputs.  If power-supply sequencing is not

possible, protect the devices from overvoltage by

adding two small signal diodes in series with the supply

pins (Figure 1).  Adding the diodes reduces the analog

signal range to 1V below V+ and 1V below V-, but low

switch resistance and low leakage characteristics are

unaffected.  Device operation is unchanged, and the

difference between V+ to V- should not exceed +44V.
