Overview
The DG307ACJ+ is a dual single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It utilizes CMOS technology and is housed in a 14-pin PDIP package. The device operates with a single supply voltage ranging from 5 V to 30 V, or dual supplies of ±5 V to ±15 V. Key electrical specifications include a maximum on-resistance of 125 Ohms, an on-time of 250 ns, and an off-time of 150 ns. The component supports a continuous current of 30 mA and functions within a commercial temperature range of 0°C to +70°C.
Feature Summary
- Dual SPDT configuration providing two independent switching channels
- CMOS construction for low power consumption and high input impedance
- TTL-compatible logic inputs for direct interfacing with digital control circuits
Applications
- Signal routing in data acquisition systems
- Multiplexing sensor inputs in industrial instrumentation
- Test and measurement equipment signal paths
Procurement Notes
Verify the specific suffix 'C' indicates the commercial temperature grade (0°C to +70°C). Confirm the '+'' denotes RoHS compliance. Check for obsolescence status as older CMOS switches may have limited availability. Ensure the PDIP-14 package matches the target PCB footprint requirements.
Selection Notes
Select this component when dual SPDT switching is required with TTL compatibility. Compare on-resistance and leakage current against system signal integrity needs. Consider the PDIP package size constraints versus surface-mount alternatives if board space is limited. Verify voltage headroom against the maximum 30 V single supply limit.
Part Context
This part belongs to the DG307 family of CMOS analog switches. It serves as a discrete switching solution for moderate-speed applications. The device complements other multiplexer and switch ICs in the portfolio, offering a simple two-channel alternative to higher-density solutions.
Replacement Considerations
The DG307ACN is a pin-compatible variant. Other CMOS SPDT switches from the manufacturer may offer different speed or resistance characteristics. Verify pinout compatibility before substituting with generic CMOS SPDT devices.
