The SN75C3238EDBRG4 is a bidirectional bus peripheral with a voltage level-translation capability. It can be used as a bus driver, receiver, or transceiver, which makes it a useful device for building an interface between two data buses whose logic levels are different. This article explains the working principle of this device, as well as its common applications.

Features and Applications

SN75C3238EDBRG4 is a member of the Texas Instruments’ portfolio of bidirectional bus transceivers. It is an eight-channel device designed to facilitate communication between two logic families of different voltage levels, such as 3.3V, 5V, and 12V. The device provides both open-drain and totem-pole output. It features a slew-rate-limited driver, a low-voltage threshold, a low-power shutdown mode, and thermal shutdown protection.

The SN75C3238EDBRG4 is typically used as an interface between two buses of different voltage levels. Its wide operating range allows it to be used in applications such as data buses, peripheral controllers, and expansion cards for computers. Its flexible logic levels also make it useful for communicating with a variety of devices, including non-volatile memory, I/O ports, and microprocessors. Moreover, this device can be used in any system that requires level translation between two data buses.

Working Principle

The SN75C3238EDBRG4 can be used as a driver, receiver, or transceiver. A driver is used to provide logic levels to a data bus, while a receiver is used to receive logic levels from the bus. A transceiver, on the other hand, can act as both a driver and receiver, transferring data between buses of different voltages.

When used as a driver, this device accepts a logic input and provides a corresponding logic output. The output level varies depending on the input level, allowing for communication between two different logic families. When used as a receiver, the device accepts the logic input from one logic family and translates it into the levels of the other logic family.

When used as a transceiver, the device can bridge the gap between two devices by translating data from one logic family to another. This device can achieve level translation even in the presence of high capacitive loads. It also offers built-in protection against short circuits and over-current.

Conclusion

The SN75C3238EDBRG4 is a versatile device capable of transferring data between two logic families of different voltages. It can function as a driver, receiver, or transceiver, enabling it to bridge the gap between two communication buses. This device features slew rate control, low voltage threshold, thermal shutdown, and a low-power shutdown mode, making it an ideal device for a wide range of applications.
