The ET74LVCSZ17 is a single-channel, non-inverting buffer from the 74LVC logic family. It operates over a wide supply voltage range of 1.65V to 5.5V, making it versatile for mixed-voltage systems. With a high output current of 32mA, it can drive heavy loads while maintaining signal integrity. The push-pull output eliminates the need for external pull-up resistors, simplifying board design. This buffer is ideal for signal conditioning, bus interfacing, and level-shifting applications in consumer, industrial, and automotive electronics. Its compact SC-70-5 and SOT-353 packages save valuable PCB space.
- Wide 1.65V to 5.5V Supply Range: Compatible with both 3.3V and 5V systems, simplifying design.
- High 32mA Output Current: Drives heavy capacitive loads and long traces without signal degradation.
- Extended Temperature Range (-40°C to 125°C): Suitable for automotive and industrial environments.
- Push-Pull Output: Eliminates external pull-up resistors, reducing component count and cost.
Bus Interfacing
Use the ET74LVCSZ17 to buffer address or data lines between a microcontroller and memory or peripheral devices. Its 32mA output current ensures reliable signal integrity over short PCB traces.
Signal Buffering for Sensors
Buffer weak sensor outputs before feeding them into an ADC or logic input. The non-inverting function preserves the original signal polarity, while the wide voltage range supports various sensor supplies.
Level Shifting
With a 1.65V to 5.5V supply range, this buffer can act as a simple level shifter between 1.8V and 3.3V or 5V logic domains, ensuring proper logic thresholds.
Clock Distribution
Drive multiple loads from a single clock source. The high output current and fast propagation delay of the 74LVC family minimize skew and maintain signal quality.
Automotive ECUs
In automotive electronic control units, this buffer can condition signals from switches or sensors. Its -40°C to 125°C temperature range meets stringent automotive requirements.
Industrial Controls
For PLCs and industrial sensors, the ET74LVCSZ17 provides robust buffering in noisy environments. The push-pull output reduces susceptibility to external interference.
