74HC238PW,118

The Nexperia 74HC238PW,118 is a versatile 3-to-8 line decoder/demultiplexer IC. 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 flexible control and easy parallel expansion to create larger decoders, such as a 1-of-32 decoder using four '238 ICs and an inverter.

This component is suitable for demultiplexing applications by utilizing one of the active-low enable inputs as the data input. It operates across a wide supply voltage range of 2.0 V to 6.0 V and maintains high noise immunity. The 74HC238PW,118 is specified for operation in temperatures ranging from -40 °C to +125 °C.

Designed for surface mount applications, the 74HC238PW,118 comes in a 16-TSSOP package with a body width of 4.4 mm. Its features include CMOS low power dissipation and input clamp diodes that enable the use of current-limiting resistors for interfacing inputs to voltages exceeding VCC. This makes it an ideal choice for memory chip select decoding and other logic control applications.
