MAX14805/MAX14806 19-5253 Rev 0 4/10 16-Channel (Two Banks of 8-Channel), High-Voltage Analog Switches General Description Features The MAX14805/MAX14806 provide high-voltage switch- S HVCMOS Technology for High Performance ing on 16 channels for ultrasonic imaging. Both devices S Two Sets of 8-Channel SPST High-Voltage Analog are ideal for the following applications: banks selection in Switches biplane or triplane ultrasound probes and relays replace- S DC to 20MHz Low-Voltage Analog Signal ment. The devices utilize 200V process technology to Frequency Range provide sixteen high-voltage, low-charge injection SPST S +2.7V to +5.5V Logic Supply Voltage switches, controlled by a digital interface. S Ultra-Low (0.1A) (typ) Quiescent Current The MAX14805/MAX14806s output switches are con- figured as two sets of eight SPST analog switches. The S Low-Charge Injection, Low-Capacitance 20I switches are controlled by two input logic controls, DIN1 Switches and DIN2 (respectively for switch 0 to 7 and switch 8 S -77dB (typ) Off-Isolation at 5MHz (50I) to 15). The MAX14806 features integrated 40kI bleed S Flexible, High-Voltage Supplies (V - V = resistors on each switch terminal, which help to reduce PP NN 230V) voltage buildup in capacitive loads such as piezoelectric elements. Applications The MAX14805/MAX14806 operate with a wide range of Medical Ultrasound Imaging high-voltage supplies, including V /V = +100V/-100V, PP NN +200V/0V, and +40V/-160V. The digital interface oper- Nondestructive Test (NDT) ates from a separate V supply from +2.7V to +5.5V. DD Digital inputs DIN1, DIN2, and LE operate on the V DD supply voltage. The MAX14805CCM+ is a drop-in replacement for the Supertex HV2631. The MAX14806CCM+ is a drop-in replacement for the Supertex HV2731. Both devices are available in the 48-pin, TQFP package and are specified for the extended -40NC to +85NC temperature range.

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.
