The 74HC238BQ,115 from Nexperia USA Inc. is a versatile 3-to-8 line decoder/demultiplexer. It decodes three binary weighted address inputs (A0, A1, A2) to eight mutually exclusive outputs (Y0 to Y7). The device includes three enable inputs (E1, E2, E3) which allow for easy parallel expansion to larger decoding functions, such as a 1-of-32 decoder with additional ICs.
This component is suitable for memory chip select decoding and can also function as an eight-output demultiplexer. It supports a wide supply voltage range from 2.0 V to 6.0 V and operates across a temperature range of -40 °C to +125 °C. The device is available in a 16-DHVQFN package with surface mount mounting type.
Key electrical characteristics include a quiescent current of 5.2mA and robust ESD protection, exceeding 2000 V for HBM and 1000 V for CDM. The inputs include clamp diodes, enabling the use of current-limiting resistors for interfacing to voltages exceeding VCC.
