Drivers, Receivers, Transceivers

The SN65C3238EDWG4 is an interface device designed as an I/O transceiver for applications where fast and/or low-power digital data is to be transmitted. It is an integrated circuit (IC) package containing two full-duplex bus transceivers that employ separate transmit and receive enable pins.

Applications

The SN65C3238EDWG4 is suitable for a wide variety of application areas, including:

• Industrial automation
• Networking
• Office automation
• Computer peripherals
• Audio/video equipment
• Telecommunications
• Automotive
• Consumer electronics

Features

• Very low power consumption (max. 5 mA)
• Independent receive and transmit inputs
• High speed transfer—up to 1 Mbps
• Compact 8-pin SSOP package
• Highly efficient data encoding/decoding
• Edge-triggered data strobe
• Slew rate limited receiver inputs
• Idle bus current (all pins except SDA and SCL) of 0.2 μA
• Latch-up tested to > 100 mA

Working Principle

The SN65C3238EDWG4 is a dual-channel transceiver that operates on the same simple principle as a regular full-duplex transceiver, except that it can handle two data streams instead of one. It functions by receiving and transmitting data on separate channels while still maintaining a single communication link. The IC consists of two identical transceiver channels, each with a transmit enable (TxEn) and a receive enable (RxEn) pin for each channel. The device can be used for communication between two controllers or devices that share the same bus. It utilizes an internal signal control logic to decode the received data and encodes only valid data for transmission. It also features low power D-A/A-D conversion for better accuracy, as well as slew-rate limited inputs to reduce signal distortion.

Conclusion

The SN65C3238EDWG4 is a versatile and highly efficient dual-channel transceiver, enabling high-speed data transfer while consuming very low power. It is suitable for a wide range of industrial, networking, office automation, computer peripheral, audio/video, telecommunications, automotive and consumer electronic applications. The device enables independent receive and transmit inputs, provides efficient data encoding/decoding, features a low power D-A/A-D conversion, has edge-triggered data strobe and slew-rate limited receiver inputs.
