Key Features
- Dual active-low output enable pins allow selective tri-stating of two independent groups, simplifying bus multiplexing
- HC/UH CMOS family provides wide supply voltage operation with low quiescent current for power-efficient bus buffering
- 50 pF load capacitance rating supports driving standard TTL bus lines without additional buffering
- SOIC-16 package with 16 leads enables compact PCB placement for data bus and address line driving applications
Applications
The CD74HC366MG4 serves as a hex inverting bus driver in microprocessor and microcontroller systems where address or data bus signals require buffering and controlled tri-state operation. Its dual output enable inputs make it well suited for memory expansion boards, where independent enable control of two groups of 3 lines manages bus contention. It is also used in industrial PLCs and test equipment backplanes requiring reliable signal drive at 50 pF load capacitance.

Frequently Asked Questions
How does the dual output enable on the CD74HC366MG4 help manage bus contention in a memory expansion design?
The CD74HC366MG4 provides two separate active-low output enable pins, each controlling 3 of the 6 inverting driver outputs, so a memory controller can independently tri-state each group to avoid bus contention when switching between two memory banks. With a 6 mA sink current per output and 50 pF load capacitance rating, it drives standard CMOS and TTL bus lines reliably in memory interface designs.
What supply voltage range does the CD74HC366MG4 support, and how does it perform at 3.3 V compared to 5 V?
The CD74HC366MG4 belongs to the HC/UH CMOS family, which supports a supply voltage range of 2 V to 6 V, making it compatible with both 3.3 V and 5 V logic systems. At 3.3 V the propagation delay increases slightly compared to 5 V operation, so designs requiring maximum switching speed above 50 MHz should verify timing margins against the specific datasheet curves for the operating voltage.
For a 16-bit address bus buffering application, how many CD74HC366MG4 devices are needed and what total sink current can they provide?
Each CD74HC366MG4 buffers 6 lines, so 3 devices are needed to drive all 16 address bus lines with 2 lines unused or used for control signals. With 6 mA sink current per output, each IC can collectively sink up to 36 mA across its 6 outputs, and 3 ICs together provide up to 108 mA total sink capacity for worst-case simultaneous switching scenarios on a heavily loaded PCB bus.
What is the SOIC-16 footprint of the CD74HC366MG4 and how does it compare to a DIP-16 alternative for a prototype board?
The CD74HC366MG4 in SOIC-16 has a 10 mm body length and 1.27 mm lead pitch, occupying roughly 60 mm2 of PCB area compared to about 185 mm2 for a through-hole DIP-16 equivalent. While a DIP-16 is easier to prototype on breadboards, the SOIC-16 reduces board space by approximately 3x and is compatible with standard SMD reflow assembly for production designs.
