Product Overview
3-to-8-line inverting decoder/demultiplexer; three address inputs, three enables, eight mutually exclusive active-LOW outputs. Supports demultiplexing and memory chip-select decoding.
The 2–6 V operating range supports 3.3 V and 5 V logic rails, but the CMOS VIH requirement must be checked at the actual rail. Active-LOW mutually exclusive outputs suit chip-select and one-of-eight enable generation.

Selection Notes
HC CMOS input thresholds; SO16 versus TSSOP16/DHVQFN16 package; supply range; temperature range; output-current and timing requirement.
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. ; VIH: at VCC=2.0 V, min 1.5 V; at VCC=4.5 V, min 3.15 V. ; ESD: HBM >2 kV; CDM >1 kV. ; Thermal: RθJA 93 K/W, RθJC 53 K/W.
Design Considerations
-
- Verify every input meets the HC VIH/VIL limits at the selected VCC, temperature, and interface source. 2. Verify output sink/source current does not exceed the stated ±5.2 mA capability under the required VOH/VOL. 3. Check enable polarity: E1/E2 are active LOW and E3 is active HIGH. 4. Check SO16 SOT109-1 footprint, pinout, thermal assumptions, and assembly process.
Application Fit
Memory/chip-select decoding, 1-of-8 demultiplexing, and expansion to 1-of-32 using multiple devices.
