Frequently Asked Questions
What voltage levels can the SN74AXCH4T245RSVR translate between?
The SN74AXCH4T245RSVR uses a dual-supply architecture with separate VCCA and VCCB pins, enabling translation between two independent voltage levels. It supports a wide range of voltage combinations, allowing interfacing between common logic families such as 1.2V, 1.8V, 2.5V, 3.3V, and 5V systems without additional external components.
Is the SN74AXCH4T245RSVR bidirectional?
Yes, the SN74AXCH4T245RSVR is a bidirectional bus transceiver, meaning data can be transferred in both directions between Port A and Port B. The direction of data flow is automatically determined by the voltage levels on each port, with an active-low enable pin controlling whether the outputs are active or in high-impedance state.
What package does the SN74AXCH4T245RSVR use?
The SN74AXCH4T245RSVR is housed in a 16-UQFN (Ultra-thin Quad Flat No-Lead) package. This extremely compact surface-mount package minimizes board space consumption and is ideal for high-density PCB layouts in space-constrained applications such as mobile devices, wearables, and miniaturized embedded systems.
What operating temperature range does the SN74AXCH4T245RSVR support?
The SN74AXCH4T245RSVR operates over an extended temperature range from -40°C to 125°C, meeting industrial and automotive grade requirements. This wide temperature range ensures reliable operation in harsh environments including outdoor industrial equipment, automotive electronics, and systems exposed to significant thermal variation.
