Product Overview: CD4556BMT from Texas Instruments

The CD4556BMT is a high-performance CMOS Dual Binary to 1-of-4 Decoder/Demultiplexer manufactured by Texas Instruments, a leader in semiconductor design and production. This integrated circuit is designed to provide highly flexible decoding capabilities for a wide range of applications, from automated systems to consumer electronics.

The device features two independent decoders, each accepting two binary weighted inputs (A0, A1 for the first decoder and A2, A3 for the second) and providing four mutually exclusive outputs (O0 to O3 for the first decoder and O4 to O7 for the second). These outputs are activated on a high level, and each decoder has its own active low enable input (E1 for the first decoder and E2 for the second), which facilitates the ease of expanding the decoding lines through cascading.

Constructed with silicon gate CMOS technology, the CD4556BMT offers exceptional power-saving features, making it suitable for battery-operated devices. It has a wide operating voltage range from 3V to 18V, providing versatility in various power environments and ensuring compatibility with both TTL and CMOS logic levels. This flexibility allows designers to integrate the CD4556BMT into a broad spectrum of applications without concern for voltage compatibility issues.

The device is available in a surface-mount package, specifically in the SOIC-16 (Small-Outline Integrated Circuit) form factor, providing a compact footprint for space-constrained applications. The CD4556BMT's operational temperature range spans from -55°C to 125°C, ensuring reliability and stable performance across extreme environmental conditions.

Overall, the CD4556BMT is a robust and reliable choice for designers looking to implement decoding functions in their digital systems. With its low power consumption, wide voltage range, and operational stability, the CD4556BMT from Texas Instruments stands out as a practical solution for a multitude of decoding applications.
