- Six independent channels in a single 16-pin SOIC reduce component count and simplify bus buffering and signal inversion tasks
- High-speed HC/UH CMOS family delivers fast propagation delays with low static power consumption compared to bipolar TTL logic
- Specified for 50 pF load capacitance and 4 mA output drive, ensuring reliable signal integrity on capacitively loaded PCB traces
Applications
The CD74HC4049MT is commonly used as a signal buffer and voltage-level translator between CMOS and TTL logic families in microcontroller-to-peripheral interfaces, memory address buffers, and bus-driving applications. Its six inverting channels make it ideal for generating complementary control signals or rebuilding degraded logic levels on long PCB traces. It is also used in clock distribution networks and multi-chip digital systems that require driving multiple capacitive loads simultaneously.
