74LCX125TTR Description

Short technical summary and product information.

The 74LCX125TTR from STMicroelectronics is a low-voltage CMOS quad bus buffer featuring 3-state outputs. It is manufactured using advanced sub-micron silicon gate technology, providing high-speed performance with low power consumption. This device is ideal for 3.3V applications and can interface with 5V signals due to its 5V tolerant inputs and outputs.

 

Key electrical characteristics include a maximum propagation delay of 5.2 ns at 3V, and symmetrical output impedance with a minimum drive capability of 24 mA at 3V. The operating voltage range is from 2.0V to 3.6V. The device also includes power-down protection on inputs and outputs, and latch-up performance exceeding 500 mA.

 

With ESD protection rated at 2000V (HBM), 200V (MM), and 1000V (CDM), the 74LCX125TTR offers robust protection against static discharge. It is pin and function compatible with the 74 series 125. The device is supplied in a TSSOP14 package suitable for surface mounting and is available on tape and reel.

 

Applications for this buffer include automotive, industrial, computer, and consumer electronics where reliable signal buffering and interfacing are required.
