概要
Description
CD74HC238PW is a 3-to-8 line decoder/demultiplexer from the 74HC CMOS family, supplied in a PW package (14-pin plastic package).
Key details:
- Inputs: three address lines A, B, C; three enables: G1 (active HIGH), G2A and G2B (both active LOW).
- Outputs: Y0–Y7 are active LOW; when enabled, the output corresponding to the ABC value goes LOW and all others go HIGH. If not enabled, all outputs are HIGH.
- Supply: Vcc typically 4.5–5.5 V (74HC devices operate roughly 2–6 V).
- Applications: address decoding, demultiplexing/ routing signals, enabling one of several devices in a bus, display/data selection.
- Characteristics: fast CMOS performance with low static power; 14-pin package (PW variant).
Summary: It decodes a 3-bit input into one of eight active-LOW outputs when properly enabled, making it useful for simple digital demux and address-decoding tasks in 5V CMOS logic systems.

Plastic Small Outline Package (SOIC), 16-pin.
Pinout
- Pin count: 16 pins (DIP, Plastic Package Wide variant, CD74HC238PW).
- Function: 3-to-8 line decoder/demultiplexer with three address inputs A, B, C; three enables (G1 active HIGH; G2A and G2B active LOW); eight outputs Y0–Y8 (actually Y0–Y7) that are active LOW. When enabled, the selected output goes LOW corresponding to the ABC code; all other outputs are HIGH. If not enabled, all outputs remain HIGH.
