CD74HC125QPWRG4Q1 - Texas Instruments High-Speed CMOS Logic Quad Bus Buffer

The CD74HC125QPWRG4Q1 from Texas Instruments is a high-speed CMOS logic quad bus buffer that offers the functionality of non-inverting buffers with 3-state outputs. Designed to be used in automotive and industrial applications, this device is part of the HC family, which is known for its high noise immunity and low power consumption. The CD74HC125QPWRG4Q1 is characterized for operation from -55°C to 125°C, making it suitable for extreme environmental conditions.

Each buffer of the CD74HC125QPWRG4Q1 has a separate output-enable (OE) input which, when HIGH, puts the output in the high-impedance state. This feature allows for the disconnection of the output from the bus line, enabling multiple devices to share the same bus without interference. The device is capable of driving bus lines or buffer memory address registers with its high-current outputs.

The CD74HC125QPWRG4Q1 comes in a TSSOP (Thin Shrink Small Outline Package) with 14 pins, offering a compact footprint for space-constrained applications. Its enhanced product features include improved latch-up performance and ESD protection, ensuring reliability and robustness in complex electronic systems.

Key features of the CD74HC125QPWRG4Q1 include:

• Wide operating voltage range of 2V to 6V
• High output current: -5.2 mA at VCC = 4.5V
• Low power consumption: 20 μA maximum ICC
• Low input current of 1 μA maximum
• Significant power reduction compared to LSTTL logic ICs
• HC types: 2V to 6V operation
• High noise immunity: NIL = 30%, NIH = 30% of VCC at VCC = 5V

The CD74HC125QPWRG4Q1 is ideal for automotive systems, signal gating, and buffer memory address registers, providing a reliable solution for high-performance logic buffering requirements. Its robust design and versatile features make it an excellent choice for designers looking to enhance the integrity and flexibility of their digital systems.
