What are the key features of CD74HC366E?
- 6-bit 3-state inverting bus driver with dual active-low output enable for flexible bus isolation and multiplexing
- Wide 2V to 6V HC CMOS supply range ensuring compatibility with 3.3V and 5V logic bus systems
- 16-pin PDIP package with 50pF load capacitance support for reliable high-speed unidirectional bus driving in industrial designs
What is CD74HC366E used for?
The CD74HC366E is used in microprocessor and microcontroller bus systems requiring unidirectional 6-bit data buffering with tri-state output control, such as address latches, data bus drivers, and memory interface circuits operating from 2V to 6V supply rails. Its dual enable inputs allow two independent groups of outputs to be selectively driven or tri-stated, simplifying multi-master bus arbitration in embedded systems.

Frequently Asked Questions
What supply voltage range does the CD74HC366E support and how does its HC family classification affect drive strength?
The CD74HC366E operates from 2V to 6V using the HC CMOS logic family, which provides higher output drive current than standard CMOS buffers. This enables it to drive 50pF load capacitances at 6-bit width without additional buffers in 3.3V or 5V shared bus systems used in embedded and industrial applications.
How do the dual output enable pins on the CD74HC366E benefit bus arbitration in multi-master designs?
The CD74HC366E features 2 independent active-low output enable pins that each control a subset of the 6 output bits, allowing a system controller to selectively tri-state portions of the bus. This supports multi-master arbitration in shared address or data buses where different bus masters need to drive separate output groups.
Why would a designer choose the 3-state inverting CD74HC366E over a non-inverting bus driver like the 74HC365?
The CD74HC366E inverts its inputs before driving the bus, which is useful in systems where the upstream logic is already inverted or where an inverting buffer is needed to restore signal polarity. Combined with 3-state tri-state outputs and a 2V to 6V range, it reduces external inverters in 6-bit bus isolation circuits.
Is the CD74HC366E RoHS compliant and is it still in active production for new designs?
The CD74HC366E carries JESD-609 code e4 confirming RoHS lead-free compliance and has a YTEOL of 15, indicating it remains in active production. This makes it a reliable long-term choice for new 6-bit bus driver designs requiring a 2V to 6V PDIP-16 component with dual output enable and tri-state outputs.
