What are the key features of CD74HC366EG4?
- Hex inverting buffer with 3-state output enable for bus-sharing and multi-master data line architectures
- Wide supply voltage of 2 V to 6 V supporting both 3.3 V and 5 V digital logic systems
- 16-pin DIP through-hole package ideal for prototyping and low-volume production boards
What is CD74HC366EG4 used for?
CD74HC366EG4 is used in bus interface circuits where multiple drivers share a common data line, with the 3-state outputs allowing only one driver active at a time to prevent bus contention. It serves as an inverting line driver in memory address demultiplexing, display segment driving, and I/O port expansion for microcontrollers. The 16-pin DIP package supports breadboard assembly and hand-soldering for quick prototyping.

Frequently Asked Questions
What makes CD74HC366EG4 different from CD74HC04E for bus driver applications?
CD74HC366EG4 features 3-state (tri-state) outputs controlled by an output enable pin, allowing the device to disconnect from a shared bus when not active. CD74HC04E is a simple hex inverter with always-active outputs, making it unsuitable for multi-driver bus configurations. The 3-state feature of CD74HC366EG4 is essential for 6-bit bidirectional bus interfaces.
How many inverting buffer channels does CD74HC366EG4 provide and what package does it use?
CD74HC366EG4 provides 6 independent inverting buffer channels with 3-state outputs in a 16-pin DIP package. All 6 channels share a common output enable control input, so all buffers are enabled or tri-stated simultaneously, which simplifies bus arbitration logic in 6-bit wide data bus designs.
At what supply voltage does CD74HC366EG4 operate, and what input logic levels does it accept?
CD74HC366EG4 operates from 2 V to 6 V supply voltage, with CMOS-compatible input thresholds at approximately 50% of VCC. At 5 V, the VIH minimum is 3.5 V and VIL maximum is 1.0 V, providing good noise margin. At 3.3 V supply, thresholds scale proportionally to maintain CMOS noise immunity of at least 0.5 V margin.
In which system bus expansion scenarios is CD74HC366EG4 preferred over a non-inverting buffer like CD74HC365?
CD74HC366EG4 is chosen when the downstream logic requires an inverted signal polarity, such as active-low chip select expansion or LED segment driving where sink-current drive with inverted data is needed. In contrast, CD74HC365 passes data non-inverted. Both share the same 6-channel 3-state structure and 16-pin DIP footprint, so swapping between them requires only firmware or logic inversion adjustments.
