95015 PA2268 PA2268T LoPro Dual SPDT Analog Switch ™ ANALOG PRODUCTS DIVISION Features CMOS Technology for Bus and Analog Applications Low On-Resistance: 0.6Ω. Vcc Range: 1.8V to 4.2V Rail-to-Rail Signal Range High Off Isolation: -75dB @ 100kHz Crosstalk Rejection: -90dB @ 100kHz Break-Before-Make Switching Extended Industrial Temperature Range: –40°C to 85°C © LoPro Packaging (Pb-free): 10-Lead Micro Package ProTek Analog’s PA2268 is a dual high-bandwidth, fast single-pole double throw (SPDT) CMOS switch. It can be used as an analog switch or as a low-delay bus switch. Specified over a operating power supply voltage, 1.8V to 4.2V, the PA2268 has an On-Resistance of 0.6Ω at +2.7V. Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching. The PA2268T includes termination resistors that improve noise immunity during overshoot excursions and off isolations or pop-up noise minimization Functional Block Diagrams Applications Cell Phones PDAs MP3 players Portable Instrumentation Computer Peripherals Speaker Headset Switching Power Routing Relay Replacement Audio and Video Signal Routing PCMCIA Cards Modems NC1 NC1 NO1 COM1 NC2 IN1 NO2 COM2 COM1 NO1 IN1 IN2 NC2 Fig. 1 PA2268 COM2 NO2 IN2 Pin Descriptions Pin No. Name Description 1,3 NOX DATA Port (Normally Open) 4 GND Ground 10,2 NCX DATA Port (Normally Closed) 8,5 COMX 9 VCC Positive Power Supply 7,6 INX Logic Control Common Port / DATA Port Fig.2 PA2268T (with termination resistors) Pin Configuration (Top View) COM1 8 VDD 9 NC1 10 IN1 IN2 7 6 2 1 NO1 Logic Function Table Logic Input (INX) Function 5 COM2 4 GND 3 NO2 NC2 Ordering Information Temperature Range Package Part Number 0 NCX Connected to COMX -40 to 85 °C 10 Lead LoPro PA2268-T7 1 NOX Connected to COMX -40 to 85 °C 10 Lead LoPro PA2268T-T7 Description 2929 S Fair Lane Tempe AZ 85282 Tel: (602) 431-8101.

"Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. 2. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. 3. Control input must be held HIGH or LOW; it must not float. 4. Internal Resistance RTERM is guaranteed by design and not production tested.
