What are the key features of SN74LVCH244APWTE4?
- Octal (8-channel) non-inverting 3-state outputs allow bus sharing among multiple drivers without signal contention
- LVC family operation from 1.65 V to 3.6 V supply enables use in low-voltage mixed-signal and portable systems
- 24 mA output sink current (IOL) provides strong bus-drive capability for capacitive-load PCB traces
- Active-low output enable on two groups of four channels gives flexible partial-bus tri-state control
What is SN74LVCH244APWTE4 used for?
The SN74LVCH244APWTE4 is commonly used as an address or data bus buffer in microprocessor and microcontroller systems, isolating heavy bus loads from logic outputs. It is also applied in memory interface circuits, FPGA I/O expansion, and signal level translation between 1.8 V and 3.3 V domains. The 3-state outputs make it straightforward to implement bidirectional bus structures with external direction control logic.
