Overview
The MC74VHCT259ADTRG, produced by onsemi, is an 8-bit Addressable Latch/1-of-8 Decoder fabricated with silicon gate CMOS technology. This device is designed for high-speed operation, similar to equivalent Bipolar Schottky TTL, while maintaining the low power dissipation characteristic of CMOS technology. It features a three-stage internal circuit, including a buffer output, which provides high noise immunity and stable output. The device is versatile, offering four modes of operation: addressable latch, memory, one-of-eight decoding or demultiplexing, and reset modes. It is particularly useful for general-purpose storage applications in digital systems and can also serve as a level converter for interfacing 3.3 V to 5.0 V systems due to its full 5.0 V CMOS level output swings.
