The 74LCX257MTR is a low voltage CMOS quad 2-channel multiplexer from STMicroelectronics, designed for high-speed 3.3V applications. It features 5V tolerant inputs and outputs, making it suitable for interfacing with 5V signal environments. This device offers a wide operating voltage range of 2.0V to 3.6V and a high speed with a propagation delay of 6.0 ns at VCC = 3V.
The multiplexer is fabricated with sub-micron silicon gate and double-layer metal C2MOS technology. It is ideal for low power consumption while maintaining high speed performance comparable to 5V AC/ACT families. The 74LCX257MTR has power-down protection on inputs and outputs, and symmetrical output impedance with |IOH| = IOL = 24mA (MIN) at VCC = 3V.
It is pin and function compatible with the 74 Series 257. The device is available in a 16-SOIC surface mount package. All inputs and outputs are equipped with protection circuits against static discharge, providing 2KV ESD immunity.
Key electrical characteristics include a typical propagation delay of 6.5 ns at 2.7V and 6 ns at 3V to 3.6V. The device supports independent circuits and operates from a single supply voltage.
