SN74LVC16245ADL is an advanced low voltage Dual Bi-Directional Transceiver. It was developed to be used when the number of I/O lines available is reduced, yet bidirectional data transmission is required. It enables users to save pins and reduce component cost by providing a choice of either two-bit wide or four-bit wide operation. It also was designed with a high degree of immunity to bus contention and noise environments.

Application Field

The SN74LVC16245ADL is extensively used in data communication buses, such as the Universal Serial Bus (USB), and in industrial networking protocols such as the CANbus protocol. It is also used in many embedded systems and peripheral equipment that require bidirectional communications. The high immunity against bus contention and noise make it especially useful in environments like automotive electronics, consumer products, factory automation, networking and medical diagnostic systems that require high noise and electromagnetic interference (EMI) immunity.

Working Principle

The SN74LVC16245ADL is a 16-bit bi-directional transceiver which enables bidirectional communication over a few I/O pins. It is made up of two 8-bit wide transceivers, which can be operated either in two-bit wide or four-bit wide operation mode. The 16-bit buffer includes an Enable pin which is used to enable/disable the transceiver. It also includes two input data pins (D1 and D2) and two output data pins (Q1 and Q2). When enabled, the device will transfer data from the input pins (D1, D2) to the output pins (Q1, Q2). When disabled, the device will block any signal from the output pins.

The SN74LVC16245ADL also provides protection for data transmission against bus contention and noise environment. It has two Enable pins (E1 and E2) which are used to enable/disable the two 8-bit transceivers separately. It also has two control input pins: the Direction Control pin (DIR) and the Data Output Enable pin (DEN). The DIR pin is used to control the transmission direction. When DIR is logic high, data will be transmitted from the input pins to the output pins. When DIR is logic low, data will be transmitted from the output pins to the input pins. The DEN pin is used to selectively enable/disable data transmission. When DEN is logic high, data will be transmitted. When DEN is logic low, data will not be transmitted.

Moreover, the SN74LVC16245ADL provides protection against input surge current and output short-circuiting. Its input includes an input surge current protection circuit and its output includes protection to ensure the output voltage will remain under 6V when output short-circuiting occurs. It also has an integrated bus-hold circuit, which helps retain data when the bus voltage drops below a certain threshold. This makes the SN74LVC16245ADL well-suited for communication interface applications, which require low and controlled output current.

Conclusion

In conclusion, the SN74LVC16245ADL is an advanced low voltage Dual Bi-Directional Transceiver that is extensively used in data communication buses and industrial networking protocols. Its features such as bidirectional data communication, immunity to bus contention, noise environment protection, and surge current protection make it an ideal choice for embedded systems and peripheral equipment. The integrated bus-hold circuit makes it well-suited for communication interface applications, and the two-bit and four-bit wide operation mode can save pins and reduce component cost.
