ADG1414
The ADG1414 is a monolithic complementary metal-oxide
semiconductor (CMOS) device containing eight independently
selectable switches designed on an industrial CMOS (iCMOS®)
process. iCMOS is a modular manufacturing process combining
high voltage CMOS and bipolar technologies. iCMOS components
can tolerate high supply voltages while providing increased performance, dramatically lower power consumption, and reduce the
package size.
The ADG1414 is a set of octal SPST (single-pole, single-throw)
switches controlled via a 3-wire serial interface. On resistance is
closely matched between switches and is very flat over the full
signal range. Each switch conducts equally well in both directions and the input signal range extends to the supplies.

Figure 1.
Data is written to these devices in the form of eight bits; each
bit corresponds to one channel.
The ADG1414 utilizes a versatile 3-wire serial interface that
operates at clock rates of up to 50 MHz and is compatible with
standard SPI, QSPI™, MICROWIRE™, and DSP interface
standards. The output of the shift register, SDO, enables a
number of these parts to be daisy chained.
On power-up, all switches are in the off condition, and the
internal registers contain all zeros.

ADG1414
THEORY OF OPERATION
The ADG1414 is a set of serially controlled, octal SPST switches.
Each of the eight bits of the 8-bit write corresponds to one
switch of the device. A Logic 1 in the particular bit position
turns the switch on, whereas a Logic 0 turns the switch off.
Because each switch is independently controlled by an individual
bit, this provides the option of having any, all, or none of the
switches turned on.
SERIAL INTERFACE
The write sequence begins by bringing the SYNC line low. This
enables the input shift register. Data from the DIN line is
clocked into the 8-bit input shift register on the falling edge of
SCLK. The serial clock frequency can be as high as 50 MHz,
making the ADG1414 compatible with high speed DSPs.
Data can be written to the shift register in more or less than
eight bits. In each case, the shift register retains the last eight
bits that were written. When all eight bits have been written
into the shift register, the SYNC line is brought high again. The
switches are updated with the new configuration, and the input
shift register is disabled. With SYNC held high, the input shift
register is disabled; therefore, further data or noise on the DIN
line has no effect on the shift register.
Data appears on the SDO pin on the rising edge of SCLK
suitable for daisy chaining or readback, delayed by eight bits.
INPUT SHIFT REGISTER
The input shift register is eight bits wide (see Table 10). Each bit
controls one switch. These data bits are transferred to the switch
register on the rising edge of SYNC.

The ADG1414 contains a power-on reset circuit. On power-up
of the device, all switches are in the off condition and the
internal shift register is filled with zeros and remains so until a
valid write takes place.
The part also has a RESET/VL pin. When the RESET/VL pin is low,
all switches are off and the appropriate registers are cleared to 0.
DAISY CHAINING
The ADG1414 has a 3-wire serial interface (SYNC, SCLK, and
DIN pins) that is compatible with SPI, QSPI, and MICROWIRE
interface standards, as well as most DSPs. See Figure 2 for a
timing diagram of a typical write sequence.

For systems that contain several switches, the SDO pin can be
used to daisy-chain several devices together. The SDO pin can
also be used for diagnostic purposes and provide serial readback,
wherein the user can read back the switch contents.
SDO is an open-drain output that should be pulled to the VL
supply with an external resistor.
The SCLK is continuously applied to the input shift register
when SYNC is low. If more than eight clock pulses are applied,
the data ripples out of the shift register and appears on the SDO
line. This data is clocked out on the rising edge of SCLK and is
valid on the falling edge. By connecting this line to the DIN
input on the next device in the chain, a multiswitch interface is
constructed. Each device in the system requires eight clock
pulses; therefore, the total number of clock cycles must equal
8N, where N is the total number of devices in the chain.
When the serial transfer to all devices is complete, SYNC is
taken high. This prevents any further data from being clocked
into the input shift register.
The serial clock can be a continuous or a gated clock. A continuous SCLK source can be used only if SYNC can be held low
for the correct number of clock cycles. In gated clock mode, a
burst clock containing the exact number of clock cycles must be
used, and SYNC must be taken high after the final clock to latch
the data. Gated clock mode reduces power consumption by
reducing the active clock time.
