Description

FSL138MRTWDTU is a 3-to-8 line decoder/demultiplexer (the “138” family). It decodes three binary inputs into eight mutually exclusive outputs. When enabled, exactly one of the outputs Y0–Y7 is active, corresponding to the binary value of A, B, and C. It is commonly used for address decoding, memory chip selects, data routing, and demultiplexing in digital systems. Typical features include enable inputs and TTL/CMOS-compatible logic; exact voltage ranges, timing, and pinout depend on the specific variant. The MRTWDTU suffix encodes packaging, temperature rating, and regional options (e.g., 16-pin SOP or similar). For precise pin configuration, operating voltage, timing, and package details, consult the manufacturer’s datasheet for FSL138MRTWDTU. Example: with A,B,C = 010, the corresponding Y2 output is activated while others are deasserted.

Equivalent

FSL138MRTWDTU is a 3-to-8 line decoder/demultiplexer. Common equivalents (74xx138 family) include:
- SN74LS138N (TI)
- 74LS138 (generic TI/NXP)
- 74HC138 (NXP/Nexperia/ST)
- 74HCT138 (NXP/ON Semi)
- 74F138 (Fairchild)
- CD74HC138 (older RCA/TI lineage)
Verify pinout, speed grade (LS/HC/HCT/F) and package before substitution.

Pinout

- Pin count: 16 pins (DIP-16/SOIC-16)
- Function: 3-to-8 line decoder/demultiplexer with three enable inputs; outputs Y0–Y7 are active-low. When enabled (G1 high, G2A/G2B low), the selected output corresponding to A,B,C is driven LOW; others are HIGH.

Manufacturer

Manufacturer: Fairchild Semiconductor (now part of ON Semiconductor).
Company type: A global semiconductor manufacturer that designs and produces integrated circuits and other electronic components.

Package

8-pin SOIC (SOP-8) package.
