STMicroelectronics 74LVC161284TTR Interface IC

The 74LVC161284TTR from STMicroelectronics is a high-performance, low-voltage CMOS 18-bit universal bus driver with 3-state outputs. Designed to operate from 1.65V to 3.6V, this device is ideal for interfacing between different voltage domains in mixed 3.3V/5V systems. The 74LVC161284TTR is part of the LVC family, which stands for Low-Voltage CMOS, indicating its optimized power consumption and compatibility with low-voltage applications.

One of the key features of the 74LVC161284TTR is its bus-hold circuitry, which maintains the last active state of the bus lines if they are left floating, thereby eliminating the need for external pull-up or pull-down resistors. This can significantly simplify board design and reduce component count. Additionally, the device supports live insertion and withdrawal, minimizing power disruptions and ensuring a more reliable connection when adding or removing cards in a live system.

The 74LVC161284TTR is housed in a thin shrink small outline package (TSSOP), with a 48-pin configuration that is both space-efficient and suitable for automated assembly processes. The package is designed to optimize the thermal performance and improve the overall reliability of the device.

With its bus-friendly inputs and outputs, the 74LVC161284TTR ensures minimal loading and is capable of driving heavily loaded buses up to the maximum specification limits. The device has a wide range of applications, including bus drivers in memory address driving, microprocessor or microcontroller interface, and as a buffer for data transmission lines.

For design and development, STMicroelectronics provides comprehensive technical documentation, including datasheets, application notes, and design resources, to assist engineers in integrating the 74LVC161284TTR into their projects effectively.

Overall, the 74LVC161284TTR is a versatile, high-quality interface IC that provides a robust solution for mixed-voltage interfacing challenges, making it a valuable component in modern digital systems.
