SN75C3222PW is a wide area driver and receiver for low voltage electronic equipment used in applications including cellular phones, laptop computers and other portable devices. The SN75C3222PW is a transceiver, meaning it can both send and receive data. This makes it a highly desirable and widely used component, perfect for any application where data transmission and/or receiving is necessary.

The SN75C3222PW is designed specifically to operate in low voltage systems, with a specified operating voltage of 3.0V to 3.6V. This wide area driver and receiver has an input and output impedance of 150Ω, with supporting peak and steady-state currents of 260mA and 90mA respectively. It has an extended driving and receiving range of up to 150m, making it perfect for low voltage and wide-area applications.

The SN75C3222PW provides excellent noise protection, with a noise immunity of 35KΩ, noise reduction ratio of over 75dB, and a latch-up free receiver. This provides for a highly reliable system and a lower susceptibility to noise and interference. Furthermore, this transceiver has a stand-by power consumption of 1.3mW, making it highly energy efficient.

The SN75C3222PW features a CMOS-based two-channel plus one-channel low voltage bus transceiver. This allows the interconnection of two or three interface ports, making this transceiver perfect for systems that require multiple port interface. The SN75C3222PW has user-friendly interface pins that can be connected to I/O ports, making integration into existing systems easier.

The SN75C3222PW device uses the concept of full differential bus transceivers. It has three buses (A, B, and C), which can be used to transmit and receive data simultaneously and separately. The bus can be used to transmit and receive differential signals from and to any of the devices connected to the bus. This provides enhanced signal integrity, especially for data transmission systems operating at high speed.

In addition, the SN75C3222PW uses an advanced on-chip control circuit with pass-through signal control logic to provide extra protection against data corruption or misinterpretation. The transceiver contains a decision logic circuit with an edge-activated driver/receiver state machine, loopback test registers, and a protection circuit to prevent signal collisions. This provides improved signal integrity, reliability and flexibility.

The SN75C3222PW application field and working principle make it an ideal component for any wide-area low voltage system. Its extended driving and receiving range up to 150m, excellent noise immunity, low power consumption and flexible interface make it the perfect choice for applications in cellular phones, laptop computers and portable devices.
