The CD74AC238 decoder/demultiplexer is designed for high-performance memory-decoding and data-routing applications that require very short propagation-delay times.
The CD74AC238 is a 3-line to 8-line decoder/demultiplexer designed for high-performance memory-decoding and data-routing applications. It features very short propagation-delay times, making it suitable for use with high-speed memories where the decoder delay is negligible compared to memory access time.
The device operates over a wide supply voltage range of 1.5V to 5.5V and incorporates three enable inputs (two active-low and one active-high) to simplify cascading and data reception. It offers balanced noise immunity at 30% of the supply voltage and includes SCR-latchup-resistant CMOS circuit design with 2-kV ESD protection.
