Frequently Asked Questions

What is the output drive current and load capacitance of the 1P1G125QDCKRG4Q1?

The 1P1G125QDCKRG4Q1 supports a maximum output low current (I(ol)) of 32 mA and is characterized with a 50 pF load capacitance, making it suitable for driving standard logic loads in automotive bus applications.

Is the 1P1G125QDCKRG4Q1 suitable for automotive applications?

Yes, the Q1 suffix designates this device as AEC-Q100 automotive-qualified by Texas Instruments. It is designed for use in safety-critical automotive systems such as ADAS, body control modules, and powertrain electronics operating across a wide temperature range.

How does the 3-state output and enable control work on this device?

The 1P1G125QDCKRG4Q1 features an active-low enable (OE) pin. When OE is high, the output enters a high-impedance (3-state) mode, disconnecting the buffer from the bus. When OE is low, the device drives the output, allowing unidirectional signal buffering for bus isolation and multiplexing in complex automotive networks.

What package does the 1P1G125QDCKRG4Q1 come in and what are its key dimensions?

This device is available in the SOT-23 5-pin (JEDEC R-PDSO-G5) package, an ultra-compact surface-mount package ideal for space-constrained PCB designs. It is lead-free (Pb-free, JESD-609 e4 compliant) and RoHS-compliant with a 15-year estimated time of obsolescence (YTEOL).
