Low-V oltage, CMOS Analog Multiplexers/Switches

with Enable Inputs and Address Latching

_______________General Description

The MAX4530/MAX4531/MAX4532 are low-voltage,
CMOS analog ICs configured as an 8-channel multi­plexer (mux) (MAX4530), two 4-channel muxes
(MAX4531), and three single-pole/double-throw
switches (MAX4532). These devices are pin compatible
with the industry-standard 74HC4351/74HC4352/
74HC4353. All devices have two complementary
switch-enable inputs and address latching.

The MAX4530/MAX4531/MAX4532 operate from a sin­gle supply of +2V to +12V, or from dual supplies of
±2V to ±6V. On-resistance (150Ω max) is matched
between switches to 8Ω max. Each switch can handle
rail-to-rail analog signals. Off-leakage current is only
1nA at TA= +25°C and 50nA at TA= +85°C.

All digital inputs have 0.8V and 2.4V logic thresholds,
ensuring both TTL- and CMOS-logic compatibility when

Note 1: Voltages exceeding V+ or V- on any signal terminal are clamped by internal diodes. Limit forward-diode current to

maximum current rating.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Power-Supply Considerations

Overview

The MAX4530/MAX4531/MAX4532 construction is typi­cal of most CMOS analog switches. They have three
supply pins: V+, V-, and GND. V+ and V- drive the
internal CMOS switches and set the limits of the analog
voltage on any switch. Reverse ESD-protection diodes
are internally connected between each analog-signal
pin and both V+ and V-. One of these diodes conducts
if any analog signal exceeds V+ or V-. During normal
operation, these and other reverse-biased ESD diodes
leak, forming the only current drawn from V+ or V-.

Virtually all of the analog leakage current comes from
the ESD diodes. Although the ESD diodes on a given
signal pin are identical and therefore fairly well bal­anced, they are reverse biased differently. Each is
biased by either V+ or V- and the analog signal. This
means their leakages vary as the signal varies. The

difference

pins constitutes the analog-signal-path leakage current.
All analog leakage current flows between each pin and
one of the supply terminals, not to the other switch ter­minal. For this reason, both sides of a given switch can
show leakage currents of either the same or opposite
polarity.

The analog-signal paths and GND are not connected.
V+ and GND power the internal logic and logic-level

translators, and set both the input and output logic lim­its. The logic-level translators convert the logic levels
into switched V+ and V- signals to drive the analog sig­nals’ gates. This drive signal is the only connection
between the logic supplies and signals and the analog
supplies. V+ and V- have ESD-protection diodes to
GND.

in the two diode leakages to the V+ and V-

The logic-level thresholds are TTL/CMOS compatible
when V+ = +5V. As V+ rises, the threshold increases
slightly, so when V+ reaches +12V, the threshold is
about 3.1V—above the TTL guaranteed, high-level min­imum of 2.8V, but still compatible with CMOS outputs.

Bipolar Supplies

The MAX4530/MAX4531/MAX4532 operate with bipolar
supplies between ±2.0V and ±6V. The V+ and V- sup­plies need not be symmetrical, but their sum cannot
exceed the +13V absolute maximum rating.

Single Supply

The MAX4530/MAX4531/MAX4532 operate from a sin­gle supply between +2V and +12V when V- is connect­ed to GND. All of the bipolar precautions must be
observed. At room temperature, they actually work with
a single supply at, near, or below +1.7V, although as
supply voltage decreases, switch on-resistance and
switching times become very high.

High-Frequency Performance

In 50Ωsystems, signal response is reasonably flat up to
50MHz (see
20MHz, the on response has several minor peaks that
are highly layout dependent. The problem is not in turn­ing the switch on, but in turning it off. The off-state
switch acts like a capacitor and passes higher frequen­cies with less attenuation. At 10MHz, off isolation is
about -65dB in 50Ωsystems, becoming worse (approxi-
mately 20dB per decade) as frequency increases.
Higher circuit impedances also make off isolation
worse. Adjacent channel attenuation is about 3dB
above that of a bare IC socket, and is due entirely to
capacitive coupling.
