The 74HC4515N is a high-performance integrated circuit manufactured by NXP Semiconductors, designed to function as a 4-to-16 line decoder or demultiplexer. This versatile component is a part of the 74HC (High-Speed CMOS) family, known for its robust performance and compatibility with TTL (Transistor-Transistor Logic) levels.

Key Features

• Wide Supply Voltage Range: The 74HC4515N operates on a wide supply voltage range from 2 V to 6 V, making it suitable for various applications and compatible with other logic families.
• Low Power Consumption: Its CMOS technology ensures low power dissipation, which is critical for battery-powered and energy-efficient designs.
• High Noise Immunity: The device boasts excellent noise immunity characteristics, a hallmark of the CMOS technology, ensuring reliable operation even in electrically noisy environments.
• High-Speed Operation: It offers high-speed performance, with typical propagation delay times significantly lower than those of conventional CMOS devices.
• Multiple Output Options: The 74HC4515N provides 16 output lines, which can be controlled by 4 input lines, making it an ideal choice for applications requiring multiple output control from a limited set of inputs.
• Latch Storage Capability: It includes a latch enable (LE) input that allows the latches to store a specific input setup.
• Output Enable (OE) Feature: The device features an active LOW Output Enable (OE) input, which, when LOW, enables the outputs, and when HIGH, disables the outputs, effectively placing them in a high-impedance state.
