The 74FST3253DTR2 is a logic signal switch, multiplexer, decoder device created by Fairchild Semiconductor that provides high current outputs and is specifically designed for large size LCD display protection applications. The device consists of two independent 2:1 multiplexers with complementary outputs and a decoder that generates three output enables. Each multiplexer provides concurrent selection of two mutually exclusive data inputs from up to four sources.
The 74FST3253DTR2 offers several user-friendly features such as high current outputs (4Ω/50mA), which allows for large LCD display protection applications, and is available in a space-saving TSOP-II package with a 0.50mm pin pitch. It is also temperature-compensated, allowing for reliable operation across a wide temperature range of -40°C to +125°C, making it suitable for a variety of environments.
Application Field
The 74FST3253DTR2 can be used in applications ranging from digital display protection, including TV, LCD, and PLASMA displays, to automotive electronics systems and automotive audio systems. It is also suitable for circuit protection applications such as over-current and incomplete voltage detection. Additionally, the device can be used in medical imaging and gaming applications.
Working Principle
The 74FST3253DTR2 consists of two 2:1 multiplexers and an associated decoder. Each multiplexer provides concurrent selection of two mutually exclusive data inputs from up to four sources. The multiplexers also feature complementary outputs for combining data and bypassing low-impedance loads. The decoder generates three output enables from two control inputs and is capable of handling data rates of up to 100MHz.
When the output enable signal is asserted, it causes the A, B, or C input signal to be periodically switched to the Q output, while the complementary signal is output to Q#. The device features propagation delays of 30 ns (typical) and 300 ns (maximum) for both inputs and outputs. It also features a logic signal switch with Schmitt-trigger inputs for improved noise immunity, and the output is disabled during the low-to-high transition of the output enable.
The device offers protection from noise, current surges, and filter circuits, and is specifically designed for large size LCD display protection applications. It also offers a wide operating temperature range of -40°C to +125°C and is available in a space-saving TSOP-II package with a 0.50mm pin pitch.
Conclusion
The 74FST3253DTR2 is a logic signal switch, multiplexer, and decoder device created by Fairchild Semiconductor. It offers several features such as high current outputs, temperature-compensation, and is suitable for a variety of applications. It consists of two independent 2:1 multiplexers with complementary outputs and a decoder that generates three output enables. It is available in a space-saving TSOP-II package with a 0.50mm pin pitch and offers a wide operating temperature range of -40°C to +125°C.
