Texas Instruments SN74LV138APWR is a 3to8 line decoder/demultiplexer in a TSSOP16 package, designed for lowvoltage CMOS logic. This device provides eight activelow outputs (Y0 to Y7) and three enable inputs, enabling flexible and compact decoding and signal routing in a variety of digital designs. The SN74LV138APWR is offered in packs of 12 pieces. Key benefits Simplifies system design by performing address and signal decoding locally, reducing CPU load and bus contention. Flexible enable scheme with G1 (active ) and G2A/G2B (active low) allows precise control of when decoding occurs. Eight outputs that are driven low for the selected input combination, with all other outputs held when enabled, enabling straightforward chip select and demultiplexing schemes. Lowvoltage CMOS performance suitable for portable and energyefficient designs, operating across a Vcc range typical for LV devices. Compact TSSOP16 package provides a small footprint for dense circuit layouts without sacrificing performance. Key attributes Functionality: 3to8 line decoder/demultiplexer with 3 enable inputs (G1, G2A, G2B) and 8 activelow outputs (Y0–Y7). When G1 is and G2A/G2B are low, the selected output corresponding to inputs A, B, C goes low; all other outputs remain . If disabled, all outputs are . Inputs/Outputs: 3 select inputs (A, B, C); 8 demultiplexed outputs (Y0–Y7) with activelow logic. Enables: G1 (active ), G2A and G2B (active low) for flexible gating of the decoding operation. Voltage and compatibility: Lowvoltage CMOS device suitable for 1.65 V to 3.6 V operation, compatible with standard CMOS/TTLlevel interfaces. Package: TSSOP16 package, aligning with the SN74LV138APWR form factor for compact board designs. Brand and model: Texas Instruments SN74LV138APWR. Applications and use cases Address decoding in microprocessor or microcontroller systems: use A, B, C to select one of eight peripheral or memory devices; use Y0–Y7 as individual chip select signals. Demultiplexing control lines in digital systems: route a single set of control lines to eight devices by selecting the appropriate Y output, simplifying bus architectures. Signal routing in FPGA/ASIC support circuitry: implement compact, lowpower decoding logic for peripheral enable signals or display driver gating in portable electronics. Additional notes The device provides a reliable, lowpower solution for decoding and demultiplexing tasks in lowvoltage designs, with the familiar SN74LV138 family characteristics and TI quality. Each contains 12 pieces of SN74LV138APWR in TSSOP16 packaging, suitable for proactive stocking and production needs. In summary, the SN74LV138APWR offers a compact, lowvoltage 3to8 line decoder/demultiplexer with flexible enable inputs and eight activelow outputs, ideal for efficient address decoding, chipselect generation, and signal routing in modern digital designs.
