MC74VHC125 Quad Bus Buffer with 3State Control Inputs The MC74VHC125 is a high speed CMOS quad bus buffer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. www.onsemi.com The MC74VHC125 requires the 3state control input (OE) to be set High to place the output into the high impedance state. The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The inputs tolerate voltages up to 7 V, allowing the interface of 5 V 14LEAD SOIC 14LEAD TSSOP systems to 3 V systems.
