MC74VHC125DG

The MC74VHC125DG from ON Semiconductor is a high-speed CMOS quad bus buffer designed with silicon gate CMOS technology. It achieves high speed operation while maintaining low power dissipation. This device requires the 3-state control input (OE) to be set High to place the output into the high impedance state.

Key electrical characteristics include a wide operating voltage range of 2V to 5.5V and an operating temperature range of -55°C to 125°C. It features balanced propagation delays with a typical tPD of 3.8 ns at VCC = 5V. The device offers high noise immunity (VNIH = VNIL = 28% VCC) and low noise characteristics (VOLP = 0.8 V Max).

This buffer is packaged in a 14-SOIC (0.154", 3.90mm Width) surface mount package. It is pin and function compatible with other standard logic families and provides power-down protection on its inputs. Latchup performance exceeds 100 mA, and ESD protection is rated at >2000 V for the Human Body Model.

The MC74VHC125DG is suitable for interfacing 3.3V to 5.0V systems due to its full 5.0V CMOS level output swings. Its input structures tolerate voltages up to 5.5V, allowing for the interface of 5V systems to 3V systems.
