This document describes the features and characteristics of the 74V1T125 single bus buffer, including high-speed performance, low power dissipation, compatibility with TTL outputs, etc. It is fabricated with high-speed CMOS technology and has power down protection on inputs. This device can be used to interface 5V to 3V.
The 74V1T125 is an advanced high-speed CMOS single bus buffer fabricated with sub-micron silicon gate technology. It features a 3-state control input (G) that must be set HIGH to place the output into a high impedance state, allowing for bus sharing. The device includes power-down protection on all inputs and can accept 0 to 7V on inputs regardless of the supply voltage, making it suitable for interfacing 5V logic to 3V systems.
