Product Overview

The PCA9514DP,118 is a robust, high-quality integrated circuit (IC) developed by NXP Semiconductors. This IC is designed specifically for I²C-bus and SMBus applications, providing a hot-swappable, 2-wire bus buffer with an array of features to ensure reliable communication even in challenging environments.

Key Features

• 5V Tolerant I/Os: The PCA9514DP,118 has 5V tolerant I/O ports despite operating at a supply voltage range of 2.3V to 3.6V. This makes it compatible with legacy systems without the need for level shifters.
• Hot-Swap Capability: This IC allows live board insertion and removal from an I²C-bus without corrupting the data flow on the bus, thanks to its built-in hot-swap feature.
• No Glitch on Power-up: The device ensures that the I²C-bus lines are stable and free of glitches during power-up, contributing to the integrity of the communications.
• Low Standby Current: The PCA9514DP,118 is optimized for low power consumption with a standby current of only 5µA, making it suitable for power-sensitive applications.
• Flow-Through Pinout: A flow-through pinout design simplifies PCB layout by aligning the input and output connections in a direct path.

Applications

The PCA9514DP,118 is ideal for a variety of applications where robust I²C or SMBus communication is essential. It is particularly well-suited for:

• Hot board insertion and/or removal in servers, routers, and telecom equipment.
• Systems requiring a buffer to increase fan-out, extend bus length, or provide capacitance buffering.
• Applications that interface with multiple voltage levels or require 5V tolerant I/Os.

Package and Quality

The PCA9514DP,118 comes in a TSSOP-8 package, which is a thin shrink small outline package with 8 leads. This compact form factor is advantageous for space-constrained applications. NXP's commitment to quality ensures that this product meets high standards for reliability and performance, making it a trusted choice for critical communication tasks.

With its blend of features, the PCA9514DP,118 from NXP Semiconductors stands out as a versatile and reliable component for enhancing I²C-bus and SMBus systems.
