Frequently Asked Questions
What is the operating voltage range of the SN74LVCR2245ADW?
The SN74LVCR2245ADW belongs to the LVC (Low Voltage CMOS) family and is designed to operate from a supply voltage of 1.65V to 3.6V. Its inputs are 5V tolerant, making it suitable for interfacing 5V legacy logic with 3.3V systems without additional level-shifting components.
How does the direction control work on the SN74LVCR2245ADW?
The SN74LVCR2245ADW uses a single common DIR pin to control data flow direction for all 8 bits simultaneously. When DIR is HIGH, data flows from the B port to the A port; when DIR is LOW, data flows from A to B. A separate active-low output-enable (OE) pin tri-states all outputs when asserted HIGH, allowing bus sharing.
What package does the SN74LVCR2245ADW come in and what are its dimensions?
The SN74LVCR2245ADW is housed in a 20-pin wide-body SOIC package (JESD-30 code R-PDSO-G20), also commonly referred to as SOIC-20 with 7.5mm body width and 1.27mm pin pitch. This package is compatible with standard SMT reflow assembly and is RoHS-compliant with a Pb-free (e4) rating.
What are common alternatives to the SN74LVCR2245ADW?
Common pin-compatible or functionally similar alternatives include the SN74LVC245A (non-R version in smaller SOIC-20), Texas Instruments 74LVCH245A with bus-hold, and the NXP 74LVC245 series. The '2245' variant specifically adds the R suffix indicating enhanced ESD protection or series damping resistors depending on the product family revision.
Where can I buy SN74LVCR2245ADW and what is the typical price?
The SN74LVCR2245ADW is available through global electronic component distributors including Digi-Key, Mouser, and Arrow. Typical unit pricing starts at approximately $0.55 per piece for small quantities, with volume pricing available for larger orders. FindMyChip provides real-time stock and pricing aggregation with worldwide shipping support.
