Key Features
- Hex 3-state inverting outputs with dual output-enable pins allowing independent control of two groups of outputs for flexible bus sharing
- Wide supply voltage range of 2 V to 6 V covering both 3.3 V and 5 V digital logic systems without redesign
- CMOS HC-family technology provides high-speed switching with low quiescent current, suitable for portable and battery-operated designs
Applications
The CD74HC366M is used in microprocessor and microcontroller data bus interfaces where multiple devices must share a common bus, with 3-state outputs enabling each driver to be disabled when not selected. It serves as a signal buffer and level driver in memory expansion circuits, I/O port expansion, and backplane bus architectures. The inverting configuration also makes it useful in active-low address decoding and control-signal distribution in industrial and consumer electronics systems.

Frequently Asked Questions
What does the 3-state output mean in the CD74HC366M?
3-state outputs can be placed in a high-impedance (Hi-Z) state in addition to logic high and logic low, allowing multiple bus drivers to share the same signal lines without conflict. The CD74HC366M achieves this via its active-low output enable pins, disabling all outputs when deasserted.
What is the supply voltage range of the CD74HC366M?
The CD74HC366M operates from 2 V to 6 V, covering standard 3.3 V and 5 V logic supply rails. This wide range makes it compatible with modern low-voltage microcontrollers as well as legacy 5 V TTL-level systems.
How does dual output enable work on the CD74HC366M?
The device has two independent active-low output enable inputs, each controlling a subset of the six outputs. This allows designers to selectively enable or disable groups of outputs independently, providing additional flexibility in bus multiplexing and signal gating schemes.
What package does the CD74HC366M use and how many pins does it have?
The CD74HC366M is housed in a 16-pin SOIC (Small Outline IC) package, JESD-30 code R-PDSO-G16, with 1.27 mm pin pitch. The surface-mount package suits high-density PCB layouts and is compatible with standard pick-and-place automated assembly processes.
What is the maximum output sink current of the CD74HC366M?
Each output of the CD74HC366M can sink a maximum of 6 mA (Max I(ol) = 0.006 A), which is sufficient to drive standard CMOS and low-power TTL inputs, indicator LEDs through current-limiting resistors, or logic-level signal lines on shared buses.
