Precision, Quad, SPST Analog Switches
_______________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 lowchannel 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 +25C and less than 4nA at +85C) 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 improvements guarantee extremely low charge injection (10pC), low power consumption (35W), and electrostatic 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.
MAX364/MAX365
V+
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 operation. The MAX364/MAX365 operate from unipolar supplies 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
Figure 1. Overvoltage Protection Using Blocking Diodes
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.
