The CD74HC238EE4 is a high-speed CMOS Logic 3-to-8 Line Decoder/Demultiplexer fabricated with silicon gate CMOS technology. Manufactured by Texas Instruments, this integrated circuit is designed to be used in high-performance memory-decoding or data-routing applications requiring very short propagation delay times. The device is well-suited for implementing non-inverting decoders with memory systems, where it can minimize the effects of system decoding.

The CD74HC238EE4 takes three binary-weighted inputs (A0, A1, A2) and decodes them into one of eight mutually exclusive outputs (Y0 to Y7). The device features three enable inputs: two active-low (E1, E2) and one active-high (E3). All outputs will be high unless E1 and E2 are low and E3 is high.

This chip is characterized for operation from -55°C to 125°C, making it suitable for a wide range of applications, from industrial to military. The high noise immunity and low power consumption of the CMOS technology combined with the device's inherent speed makes it a robust and efficient solution for a variety of digital logic operations.
