onsemi MC74VHCT50ADR2G: High-Speed CMOS Logic Hex Inverter with LSTTL-Compatible Inputs

The onsemi MC74VHCT50ADR2G is a high-performance, high-speed CMOS logic integrated circuit belonging to the 74VHC family. It functions as a hex inverter, meaning it contains six independent inverters (NOT gates) within a single, compact package. This device is engineered to provide a critical interface between different logic families, offering the best of both CMOS and TTL technologies.

A primary feature of this IC is its LSTTL-compatible inputs. This design allows the device to accept input voltage levels standard for Low-Power Schottky TTL (LSTTL) logic without requiring external components. This ensures seamless and reliable operation when the MC74VHCT50ADR2G is driven by older TTL-based systems, making it an excellent choice for modernizing existing designs or for use in mixed-logic environments.

Despite its TTL-compatible inputs, the core of the device is built with advanced silicon-gate CMOS technology. This provides the inherent advantages of CMOS, including very low static power consumption and high noise immunity. Furthermore, the "VHCT" designation highlights its optimized performance, delivering high-speed operation comparable to LSTTL while maintaining the low power benefits of CMOS. The output stages are robust, capable of sourcing and sinking significant current, which is essential for driving multiple inputs or capacitive loads.

The device is offered in a surface-mount SOIC-14 package (as indicated by the "D" in the part number), which is ideal for automated assembly processes and space-constrained PCB designs. It operates over a broad voltage range, typically from 2.0V to 5.5V, providing flexibility for various 3.3V and 5V system applications.

ICGOODFIND: The onsemi MC74VHCT50ADR2G is an exceptional solution for designers seeking a high-speed, low-power interface IC. Its TTL-compatible inputs and CMOS-based core make it a versatile and reliable component for bridging logic families, ensuring signal integrity, and reducing overall system power consumption in a wide array of digital applications.
