74LCX125YTTR Description

Short technical summary and product information.

The 74LCX125YTTR is a low-voltage CMOS quad bus buffer manufactured by STMicroelectronics using sub-micron silicon gate and double-layer metal wiring C2MOS technology. It features non-inverting 3-state outputs controlled by a dedicated enable input (G). The device is designed for low-power, high-speed 3.3V applications and can interface directly with 5V signal environments on both inputs and outputs.

 

Key electrical specifications include a supply voltage range of 2.0V to 3.6V, maximum propagation delay of 5.2 ns at 3V, and symmetrical output impedance with 24 mA minimum sink/source current at 3V. The device includes power-down protection on all inputs and outputs, and balanced propagation delay with tPLH approximately equal to tPHL. ESD protection ratings are 2000V HBM, 200V MM, and 1000V CDM. Latch-up performance exceeds 500 mA per JESD 17.

 

The part is available in a 14-lead TSSOP package (0.173" width, 4.40mm) with gull wing leads, suitable for surface mount assembly. It is supplied in tape and reel packaging. The operating temperature range is -40°C to 85°C. Typical applications include automotive, industrial, computer, and consumer electronics systems requiring low-power, high-speed bus buffering and level translation.
