Overview
The Fairchild Semiconductor 74LVTH16374GX is a low-voltage, high-speed CMOS 16-bit D-type flip-flop featuring 3-STATE outputs. It operates within a supply voltage range of 2.7V to 3.6V and supports a maximum clock frequency of 160 MHz. The device provides robust output drive capabilities with a high-level output current of -32 mA and a low-level output current of 64 mA. Packaged in a 54-LFBGA format, it is designed for bus-oriented applications requiring synchronous data storage.
Feature Summary
- Contains sixteen non-inverting D-type flip-flops with 3-STATE outputs
- Designed specifically for bus-oriented applications
- Supports high-speed operation up to 160 MHz clock frequency
Applications
- Bus-oriented data storage systems
- High-speed synchronous digital circuits
- Low-voltage logic interface modules
Procurement Notes
Verify the specific package variant (LFBGA) and manufacturer origin, as onsemi acquired Fairchild's logic business. Confirm availability status, as some sources indicate this component may be obsolete or discontinued. Ensure the datasheet matches the exact suffix requirements for your design constraints.
Selection Notes
Select this component when a 16-bit parallel load capability is required in a compact BGA footprint. It is suitable for designs operating strictly within the 2.7V to 3.6V range. Consider the 3-STATE output feature if multiple devices share a common bus line in the system architecture.
Part Context
This part belongs to the LVTH series, which combines LVT speed with THS (True High Strength) output drive. It serves as a 16-bit counterpart to octal variants like the 74LVTH574. The GX suffix typically denotes the 54-pin LFBGA package configuration used for space-constrained PCB layouts.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct pin-to-pin replacements such as the 74LVTH16374MEAX only if official cross-reference data is confirmed by the manufacturer.
