STMicroelectronics 74LVX245MTR - Low Voltage Bidirectional Transceiver

The 74LVX245MTR from STMicroelectronics is a low voltage CMOS octal bidirectional transceiver designed for 3.3V VCC operation. It is part of the 74LVX family, which is known for its low voltage support and high-speed performance. This transceiver is fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology, ensuring a reliable and efficient operation.

With its bidirectional interface capability, the 74LVX245MTR can be used for asynchronous communication between data buses. The direction of data transmission is determined by the DIR input, while the output enable (OE) input can disable the device, allowing the buses to effectively be isolated. This feature makes the 74LVX245MTR ideal for multiplexed data transmission for a variety of digital communication applications.

The device offers non-inverting buffers with high current output capability for driving highly capacitive loads. It is designed to be used with 3V to 5.5V power supplies, providing a guaranteed output voltage level of VOH = 2.4V at VO = 3V. This makes it suitable for interfacing with high-speed microprocessors and can support live insertion and withdrawal (hot plugging), which is critical for server and networking applications.

Key features of the 74LVX245MTR include:

• Optimized for Low Voltage Applications: 3.3V
• 5V Tolerant Inputs and Outputs
• High-Speed Operation: tPD = 3.8ns (MAX) at TA = 25°C
• Power-Down Protection on Inputs and Outputs
• Supports Live Insertion and Withdrawal
• Low Quiescent Current: 20μA (MAX)
• Available in TSSOP and SOIC packages

The 74LVX245MTR is available in a TSSOP package, which is surface-mountable and offers a space-saving solution for PCBs. This transceiver is ideal for applications that require low-voltage operation and bidirectional data flow, such as personal computers, servers, networking, and telecommunication systems. The robust design and advanced technology make the 74LVX245MTR a reliable choice for designers looking to create efficient and high-speed data communication pathways within their electronic circuits.
