On power-up of these devices, all switches are in the OFF con-  
dition, and the internal registers contain all zeros.  
GENERAL DESCRIPTION  
The ADG714/ADG715 are CMOS, octal SPST (single-pole,  
single-throw) switches controlled via either a 2- or 3-wire serial  
interface. On resistance is closely matched between switches and  
very flat over the full signal range. Each switch conducts equally  
well in both directions and the input signal range extends to the  
supplies. Data is written to these devices in the form of 8 bits,  
each bit corresponding to one channel.  
Low power consumption and operating supply range of 2.7 V to  
5.5 V make this part ideal for many applications. These parts  
may also be supplied from a dual 2.5 V supply. The ADG714  
and ADG715 are available in a small 24-lead TSSOP package.  
PRODUCT HIGHLIGHTS  
1. 2- or 3-wire serial interface  
The ADG714 uses a 3-wire serial interface that is compatible  
with SPI , QSPI, and MICROWIRE and most DSP interface  
standards. The output of the shift register DOUT enables a  
number of these parts to be daisy chained.  
2. Single/dual supply operation. The ADG714 and ADG715  
are fully specified and guaranteed with 3 V, 5 V, and 2.5 V  
supply rails.  
The ADG715 uses a 2-wire serial interface that is compatible  
with the I2C interface standard. The ADG715 has four hard wired  
addresses, selectable from two external address pins (A0 and A1).  
This allows the 2 LSBs of the 7-bit slave address to be set by  
the user. A maximum of four of these devices may be connected  
to the bus.  
3. Low on resistance, typically 2.5 Ω  
4. Low leakage  
5. Power-on reset  
6. Small 24-lead TSSOP package
