Product Overview
3-to-8-line inverting decoder/demultiplexer with three address inputs, three enables, and eight mutually exclusive active-LOW outputs.
This is the TSSOP16 packaging option, with the same listed electrical family characteristics but higher listed RθJA than the SO16 option. Package thermal layout therefore matters more at sustained output loading.

Selection Notes
Same logic function as 74HC138D,653; TSSOP16 versus SO16; PCB area/height; thermal path; supply and interface thresholds.
Confirm the exact switching/decoding function, channel topology, logic voltage and on-state or output-drive constraints.
Manufacturer Decision-Relevant Notes
Supply: 2.0–6.0 V. ; Temperature: -40 to +125 °C. ; Input logic: CMOS. ; Typical propagation delay: 12 ns. ; Output drive capability: ±5.2 mA. ; Typical RθJA: 125 K/W. ; Typical Ψth(j-top): 4.7 K/W; RθJC: 55.5 K/W. ; ESD: HBM >2 kV; CDM >1 kV.
Design Considerations
-
- Confirm the PCB footprint and 0.65 mm-pitch TSSOP assembly capability. 2. Verify HC CMOS input thresholds against the driving MCU/FPGA at the actual supply. 3. Verify output loading and simultaneous switching against the ±5.2 mA capability. 4. Check thermal rise using the listed 125 K/W RθJA and actual copper area/airflow.
Application Fit
Memory chip-select decoding, address decoding, and one-of-eight demultiplexing.
