Frequently Asked Questions
What is the PCAXC1T45QDCKRQ1 and what is it designed for?
The PCAXC1T45QDCKRQ1 is an automotive-grade single-bit dual-supply bidirectional bus transceiver from Texas Instruments. It is designed for voltage-level translation in automotive systems, enabling bidirectional signal transfer between two different logic voltage domains while meeting AEC-Q100 automotive qualification requirements.
Does the PCAXC1T45QDCKRQ1 support bidirectional signal transfer?
Yes, the PCAXC1T45QDCKRQ1 supports bidirectional (Count Direction: BIDIRECTIONAL) signal transfer with common control. This allows signals to pass automatically in either direction between the two voltage domains based on the signal level, without requiring a direction control pin in many configurations.
What is the output drive current and load capacitance of the PCAXC1T45QDCKRQ1?
The PCAXC1T45QDCKRQ1 provides a maximum output low current of 12 mA and supports a 15 pF load capacitance. These parameters ensure sufficient drive strength for automotive PCB trace capacitances while maintaining fast signal edge rates required in automotive communication interfaces.
What package does the PCAXC1T45QDCKRQ1 use and how small is it?
The PCAXC1T45QDCKRQ1 is housed in a 6-pin SOT-23 package (JESD-30 Code R-PDSO-G6), one of the smallest available SMD packages. This ultra-compact footprint is ideal for space-constrained automotive ECU boards where minimizing board area is critical.
Is the PCAXC1T45QDCKRQ1 AEC-Q100 automotive qualified?
Yes, the PCAXC1T45QDCKRQ1 carries the AEC-Q100 automotive qualification (indicated by the Q1 suffix in the part number) and belongs to Texas Instruments' automotive product line. This qualification covers extended temperature ranges and stringent electrical reliability testing required for in-vehicle automotive applications.
