Overview
The M74VHC1GT126DT1G is a single gate noninverting 3-state buffer fabricated with silicon gate CMOS technology. It is designed to achieve high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the low power dissipation characteristic of CMOS devices. This buffer is compatible with TTL-type input thresholds and provides a full 5V CMOS level output swing. It is suitable for a wide range of applications, including logic-level translation between different voltage levels (e.g., from 3.0V CMOS to 5.0V CMOS or from 1.8V CMOS to 3.0V CMOS).
