Texas Instruments ISO1540DR
The ISO1540 and ISO1541 devices are low-power, bidirectional isolators that are compatible with I 2C interfaces. These devices have logic input and output buffers that are separated by Texas Instruments Capacitive Isolation technology using a silicon dioxide (SiO2 ) barrier. When used with isolated power supplies, these devices block high voltages, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry.
This isolation technology provides for function, performance, size, and power consumption advantages when compared to optocouplers. The ISO1540 and ISO1541 devices enable a complete isolated I 2C interface to be implemented within a small form factor. The ISO1540 has two isolated bidirectional channels for clock and data lines while the ISO1541 has a bidirectional data and a unidirectional clock channel. The ISO1541 is useful in applications that have a single master while the ISO1540 is suitable for multimaster applications. For applications where clock stretching by the slave is possible, the ISO1540 device should be used.

Maxim Integrated MAX3160EAP+
The MAX3160EAP+T is a +3V to +5.5V, 1µA, RS232/RS485/422 multiprotocol transceiver in 20 pin SSOP package. It is pin programmable as 2transmitter/2receiver RS232 interface or a single (half/full duplex) RS485/422 transceiver. This device includes low-dropout transmitter output stage and an onboard dual charge pump to allow RS232 and RS485/422 performance from a +3V to +5.5V supply. It also features pin-selectable transmitter slew rates for both RS232 and RS485/422 modes. Slew-rate limiting minimizes EMI and reduces reflections caused by improperly terminated cables allowing error-free data transmission up to 250Kbps. Disabling slew-rate limiting allows device to transmit data rate up to 10Mbps in RS485/RS422 mode and 1Mbps in RS232 mode. This circuit configuration is ideal for the design of RS232 to RS485 converters, multiprotocol buses or any application that requires both RS232 and RS485 transceivers.
- Supply voltage range is 3V to 5.5V
- Operating temperature range from -40°C to 85°C
- Integrated protection increases robustness
- Transmitters and receivers protected against wiring faults
- True fail-safe receiver prevents false transition on receiver input short or open
- Short-circuit protection over the entire common mode voltage range
- Thermal protection from excessive power dissipation
- Integrated charge-pump circuitry saves board space
- Shutdown supply current of 1µA saves power
- Eliminates the need for a bipolar ±12V supply and enables single supply operation

Texas Instruments TCA9406DCUR
The TCA9406DCUR is a 2-bit bidirectional I²C and SMBus Voltage-level Translator with an output enable (OE) input. It is operational from 1.65 to 3.6V on the A-side, referenced to VCCA and from 2.3 to 5.5V on the B-side, referenced to VCCB. This allows the device to interface between lower and higher logic signal levels at any of the typical 1.8, 2.5, 3.3 and 5V supply rails. The OE input pin is referenced to VCCA, can be tied directly to VCCA, but it is also 5.5V tolerant. The OE pin can also be controlled and set to a logic low to place all the SCL and SDA pins in a high-impedance state, which significantly reduces the quiescent current consumption. Under normal I²C and SMBus operation or other open-drain configurations, the TCA9406 can support up to 2Mbps; therefore, it is compatible with standard I²C speeds where the frequency of SCL is 100kHz (Standard-mode), 400kHz (Fast-mode) or 1MHz (Fast-mode Plus).
- 2-bit Bidirectional translator for SDA and SCL lines in I²C applications
- Provides bidirectional voltage translation with no direction pin
- Internal 10kΩ pull-up resistor on All SDA and SCL pins
- No power-supply sequencing required
- OE Input can be tied directly to VCCA or controlled by GPIO
