Overview
The PI5A121CE is a single-pole throw (SPST) normally open analog switch designed for single-supply operation. It operates within a voltage range of 2V to 6V and features logic-compatible inputs with guaranteed thresholds at 0.8V for low and 2V for high levels. The device offers an on-resistance of up to 12Ω at +5V supply and 22Ω at +3.3V supply, with a typical power consumption of 0.5µW. It provides a -3dB bandwidth of 326MHz and supports bidirectional signal conduction. Available in a 5-pin SC70 package, it ensures low distortion suitable for precision audio and video applications.
Feature Summary
- Supports bidirectional current flow when active and blocks voltages up to V+ when inactive
- Compatible with TTL and CMOS logic families for direct interface control
- Designed for low-power consumption with minimal board area footprint
Applications
- Audio and video switching and routing systems
- Battery-powered communication equipment
- Portable instrumentation devices
- Mechanical relay replacement circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging type and environmental compliance status. The 'C' designation indicates the SC70 package variant, while 'E' typically denotes Pb-free and Green specifications. Confirm that the component meets RoHS3 and REACH requirements relevant to your manufacturing region before finalizing procurement orders.
Selection Notes
Select this component for applications requiring a single-channel analog switch with wide bandwidth and low on-resistance. Ensure the operating voltage falls between 2V and 6V. Verify that the logic input levels align with your system's TTL or CMOS standards. Consider the thermal characteristics if operating near maximum temperature limits or if derating is required for continuous power dissipation.
Part Context
This part belongs to the PI5A12x family of wide bandwidth analog switches manufactured by Diodes Incorporated. The family includes the PI5A121 (SPST NO), PI5A122 (SPST NC), and PI5A124 (SPDT). These devices share similar electrical characteristics but differ in switch configuration and pinout arrangements to accommodate various signal routing needs in compact electronic designs.
Replacement Considerations
Direct substitutes include other SPST normally open analog switches from the same manufacturer series, such as the PI5A122 or PI5A124, provided the circuit topology matches the specific switch function required. Verify pin compatibility and package dimensions when replacing components to ensure mechanical fit without redesigning the PCB layout.
