The ADG738 is an 2. Single Supply Operation. The ADG738 and ADG739 are 8-channel matrix switch, while the ADG739 is a dual 4-channel fully specified and guaranteed with 3 V and 5 V supply rails. matrix switch. On resistance is closely matched between switchesand very flat over the full signal range. 3. Low On Resistance, 2.5 typical. The ADG738 and ADG739 utilize a 3-wire serial interface that 4.

On power-up,the internal shift register contains all zeros and all switchesare in the OFF state. Each switch conducts equally well in both directions when on,making these parts suitable for both multiplexing and demulti-plexing applications. As each switch is turned on or off by aseparate bit, these parts can also be configured as a type of switcharray, where any, all, or none of the eight switches may be closedat any time. The input signal range extends to the supply rails. All channels exhibit break-before-make switching action,preventing momentary shorting when switching channels. The ADG738 and ADG739 are available in 16-lead TSSOPpackages. SPI and QSPI are trademarks of Motorola, Inc.MICROWIRE is a trademark of National Semiconductor Corporation.
