Product Overview: 74HC154DB from NXP

The 74HC154DB is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). Manufactured by NXP Semiconductors, this integrated circuit is part of the 74HC series, known for its robust performance and compatibility with a wide range of applications. The 74HC154DB is specifically designed as a 4-to-16 line decoder/demultiplexer without input latches.

Key Features

• Logic Family: The device belongs to the 74HC family, which ensures high-speed operation similar to equivalent LSTTL devices.
• Decoding Capability: It features a 4-to-16 line decoder with an active LOW output. Its decoding function is facilitated by 4 binary input addresses (A0 to A3).
• Demultiplexing Function: In addition to decoding, it can be used as a demultiplexer by using one of the input lines as a data input while the others serve as control inputs.
• Output Configuration: The 74HC154DB has 16 active LOW mutually exclusive outputs.
• Power Supply: It operates on a wide power supply range from 2V to 6V, making it suitable for battery-operated devices and low-power applications.
• Output Current: High current output capability with 25 mA at the outputs, allowing for direct drive of LEDs and other devices.
