Product Overview: CD74AC138E from Texas Instruments

The CD74AC138E is a high-speed CMOS logic 3-to-8 line decoder/demultiplexer designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This integrated circuit (IC) is part of the advanced CMOS (AC) family, which boasts a faster speed than the standard CMOS logic while maintaining the low power dissipation characteristic of the CMOS integrated circuits.

With its robust design, the CD74AC138E effectively decodes three binary-coded inputs into one of eight mutually exclusive outputs when both the enable inputs, E1 and E2, are low. The third enable input, E3, is high. This feature makes the CD74AC138E an ideal choice for implementing non-inverting 3-to-8 decoders without external inverters, or for constructing a 3-to-8 line decoder with just three ICs. It is commonly used in a wide range of applications including data multiplexing, device selection, and memory address decoding.

The CD74AC138E operates over a broad voltage range of 2V to 6V and offers a balanced propagation delay and transition times, ensuring high performance in a variety of system applications. This level of versatility allows designers to integrate the decoder/demultiplexer into both new and existing designs with minimal power consumption and maximum efficiency.

Key features of the CD74AC138E include:

• High-speed CMOS technology
• Typical operating voltage range of 2V to 6V
• Low power consumption
• High noise immunity characteristic of CMOS devices
• Three binary select inputs to eight mutually exclusive outputs
• Multiple enable inputs for easy expansion
• Standardized, symmetrical output characteristics
