What are the key features of CD74HC366EE4?

Hex inverting buffer with dual active-low output enable for flexible bus tri-state control
High-speed HC/UH CMOS family with 50 pF load drive capability at 2 V to 6 V supply
16-pin PDIP through-hole package for easy prototyping and industrial control board assembly

What is CD74HC366EE4 used for?

CD74HC366EE4 is used to buffer and invert logic signals between microcontrollers and bus-connected peripherals, where tri-state control via dual enable inputs prevents bus contention. It is well suited for memory address decoding, data bus buffering, and signal distribution in embedded systems operating from 3.3 V or 5 V rails. The CMOS technology enables low quiescent current draw, important in battery-backed or low-power industrial controller designs.

Frequently Asked Questions

How does the dual output-enable structure of CD74HC366EE4 simplify bus multiplexing designs?

CD74HC366EE4 provides 2 independent active-low output enable pins that are internally ANDed, so the 6 output buffers tri-state only when both enables are high. This dual-enable topology allows designers to cascade enable logic without external gates, reducing component count in 8-bit or 16-bit bus multiplexers operating at 2 V to 6 V supply voltage.

What drive strength does CD74HC366EE4 offer compared to standard CMOS buffers at 5 V?

At 5 V supply and 50 pF load capacitance, CD74HC366EE4 achieves propagation delays typically under 10 ns, consistent with the HC-family specification of 7 ns at 6 V. The output can sink and source currents of ±25 mA at 5 V, providing enough drive to directly interface with LSTTL inputs or short PCB bus traces up to 15 cm without additional line termination.

For a 3.3 V microcontroller interfacing to a 5 V legacy bus, how does CD74HC366EE4 handle the voltage mismatch?

CD74HC366EE4 operates across 2 V to 6 V supply, so it can be powered from the 5 V bus rail while accepting 3.3 V CMOS logic inputs, since the HC input threshold at 5 V VCC is approximately 1.35 V for logic low and 3.15 V for logic high. This allows a 3.3 V MCU to drive the enable and data inputs of the 16-pin DIP buffer directly without level-shift resistors, keeping BOM cost low.
