General Description
Features
The MAX4780/MAX4784 are low on-resistance, low-
voltage, quad 2:1 analog multiplexers that operate from
a single +1.6V to +4.2V supply. These devices have

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.

Detailed Description
Typical Application Circuit
The MAX4780/MAX4784 are low 0.7 (at V+ = +2.7V)
on-resistance, low-voltage, quad 2:1 analog multiplexers/
demultiplexers that operate from a +1.6V to +4.2V single
supply. CMOS switch construction allows switching
analog signals that are within the supply voltage range
(GND to V+).
RING TONE/
MAX4780
MELODY IC
When powered from a +2.7V supply, the 0.7

allows high continuous currents to be switched in a
variety of applications.

CODEC
Applications Information
Proper power-supply sequencing is recommended for all
CMOS devices. Do not exceed the absolute maximum
ratings, because stresses beyond the listed ratings can
cause permanent damage to the devices. Always
sequence V+ on first, followed by NO_, NC_, or COM_.
EXTERNAL
SPEAKER
R = 8Ω OR 32Ω
L
SYSTEM
CONTROLLER
Although it is not required, power-supply bypassing
improves noise margin and prevents switching noise
propagation from the V+ supply to other components. A
0.1µF capacitor, connected from V+ to GND, is adequate
for most applications.

resistance (see the Typical Operating Characteristics).
The switches are bidirectional, so the NO_, NC_, and
COM_ pins can be used as either inputs or outputs.
Logic Inputs
The MAX4780/MAX4784 logic inputs can be driven up
to +4.2V regardless of the supply voltage. For example,
with a +1.8V supply, A_ and EN may be driven low to
GND and high to +4.2V. Driving A_ and EN rail-to-rail
minimizes power consumption. Drive EN low to enable
the COM_ outputs. When EN is high, the COM_ outputs
are high impedance.
Layout
High-speed switches require proper layout and design
procedures for optimum performance. Reduce stray
inductance and capacitance by keeping traces short
and wide. Ensure that bypass capacitors are as close
to the device as possible. Use large ground planes
where possible.
Analog Signal Levels
Analog signals that range over the entire supply voltage
(V+ to GND) can be passed with very little change in on-

NOTES: MEASUREMENTS ARE STANDARDIZED AGAINST SHORTS AT SOCKET TERMINALS.
OFF-ISOLATION IS MEASURED BETWEEN COM AND "OFF" NO TERMINAL ON EACH SWITCH.
ON-LOSS IS MEASURED BETWEEN COM AND "ON" NO TERMINAL ON EACH SWITCH.
CROSSTALK IS MEASURED FROM ONE CHANNEL TO ALL OTHER CHANNELS.
SIGNAL DIRECTION THROUGH SWITCH IS REVERSED; WORST VALUES ARE RECORDED.

NOTES:
1. DIMENSIONING & TOLERANCING CONFORM TO ASME Y14.5M-1994.
2. ALL DIMENSIONS ARE IN MILLIMETERS. ANGLES ARE IN DEGREES.
3. N IS THE TOTAL NUMBER OF TERMINALS.
4. THE TERMINAL #1 IDENTIFIER AND TERMINAL NUMBERING CONVENTION SHALL CONFORM TO
JESD 95-1 SPP-012. DETAILS OF TERMINAL #1 IDENTIFIER ARE OPTIONAL, BUT MUST BE LOCATED
WITHIN THE ZONE INDICATED. THE TERMINAL #1 IDENTIFIER MAY BE EITHER A MOLD OR
MARKED FEATURE.
5. DIMENSION b APPLIES TO METALLIZED TERMINAL AND IS MEASURED BETWEEN 0.20 mm AND 0.25 mm
FROM TERMINAL TIP.
6. ND AND NE REFER TO THE NUMBER OF TERMINALS ON EACH D AND E SIDE RESPECTIVELY.
7. DEPOPULATION IS POSSIBLE IN A SYMMETRICAL FASHION.
8. COPLANARITY APPLIES TO THE EXPOSED HEAT SINK SLUG AS WELL AS THE TERMINALS.
9. DRAWING CONFORMS TO JEDEC MO220 REVISION C.
