STMicroelectronics 74LCX16541TTR - Low Voltage 16-Bit Buffer/Line Driver

The 74LCX16541TTR from STMicroelectronics is a high-performance, low-voltage 16-bit buffer/line driver designed for use in 3.3V LVTTL/LVCMOS systems. This integrated circuit is part of the LCX family, which is renowned for its low power consumption and high noise immunity, making it an ideal choice for interfacing with high-speed buses in a variety of digital applications.

Equipped with two separate enable inputs (nOE1 and nOE2), the 74LCX16541TTR allows each 8-bit section to be controlled independently, offering greater flexibility in system design. It is capable of driving heavily loaded outputs at 5V VCC, with a guaranteed output drive of 24mA, which ensures strong signal integrity and reduces signal distortion.

The device features a wide data bandwidth, which makes it suitable for backplane drivers or buffering for memory address registers. It operates over a broad voltage range from 2.3V to 3.6V, and its bus-hold circuitry eliminates the need for external pull-up or pull-down resistors, simplifying board design and saving board space.

The 74LCX16541TTR is characterized for operation from -40°C to +85°C, ensuring reliable performance in harsh environments. It comes in a thin shrink small outline package (TSSOP) with 48 leads, referred to by the TTR suffix, which is designed for space-saving on the PCB.

Key features of the 74LCX16541TTR include:

• 5V tolerant inputs and outputs for interfacing with 5V logic
• Power-down high impedance inputs and outputs
• Support for live insertion and withdrawal (partial power-down)
• Low quiescent power consumption
• Edge rate control circuitry for significantly improved noise characteristics

This device is RoHS compliant and is committed to environmental sustainability. STMicroelectronics provides full technical support for the 74LCX16541TTR, including detailed datasheets, application notes, and design resources to facilitate integration into your projects.

Whether you are designing high-speed data paths, extending bus lines, or simply need a reliable buffer or line driver, the 74LCX16541TTR is an excellent choice that combines performance, power efficiency, and design flexibility.
