Frequently Asked Questions
What voltage levels does the SN74LVC2T45DCTR support for translation?
The SN74LVC2T45DCTR supports voltage translation between supplies as low as 1.65V, making it compatible with 1.8V, 2.5V, 3.3V, and 5V logic levels. Port A and Port B each have separate configurable power supplies, allowing flexible bidirectional translation between two different voltage domains in a single device.
What package does the SN74LVC2T45DCTR come in?
The SN74LVC2T45DCTR is housed in an SSOP-8 (Shrink Small Outline Package, 8-pin) package, which is compact and well-suited for space-constrained PCB layouts. The package is RoHS compliant with a Pb-free (JESD-609 e3) rating, suitable for modern consumer and industrial electronics manufacturing.
Can the SN74LVC2T45DCTR be used in bidirectional bus applications?
Yes, the SN74LVC2T45DCTR is specifically designed for bidirectional bus operation with common direction control. It features 3-state outputs that allow multiple devices to share a bus without contention, making it ideal for microcontroller I/O expansion, memory interfaces, and other applications where bidirectional data flow is required.
What is the output drive current of the SN74LVC2T45DCTR?
The SN74LVC2T45DCTR provides a maximum output low current (I(ol)) of 32mA per output pin, offering sufficient drive strength for most digital bus lines. This ensures reliable signal integrity even when driving multiple loads or long PCB traces in embedded system designs.
