74ALVCH16374T

Overview

The Fairchild Semiconductor 74ALVCH16374T is a 16-bit D-type flip-flop with 3-state outputs, part of the ALVCH logic family. It operates on a single supply voltage ranging from 2.5 V to 3.6 V. The device features 5 V tolerant inputs and outputs, allowing direct interfacing with 5 V systems without level shifting. Packaged in a 48-pin TSSOP (MO-150AC), it provides high-speed data storage for bus-oriented applications while maintaining low power consumption typical of CMOS technology.

Feature Summary

• Features 5 V tolerant inputs and outputs for seamless mixed-voltage system integration
• Provides 3-state outputs to facilitate efficient bus-oriented data transfer architectures
• Includes power-down protection on all inputs to prevent floating input states during power cycles

Applications

• Bus-oriented memory mapping in embedded systems
• Data buffering between 3.3 V and 5 V logic domains
• High-speed parallel data acquisition circuits

Procurement Notes

Verify that the specific orderable part number matches the required package variant, as suffixes may indicate tape-and-reel or tube packaging options. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributor, as these attributes can vary by production batch and region. Ensure the component meets current environmental directives applicable to your target market before finalizing procurement.

Selection Notes

Select this component when designing systems requiring 16-bit synchronous data storage with mixed 3.3 V and 5 V interface capabilities. The ALVCH series is suitable for applications demanding lower power dissipation than standard LVCMOS while offering higher speed performance. Consider the 48-pin TSSOP footprint constraints and thermal requirements during PCB layout to ensure reliable operation within the specified temperature range.

Part Context

This component belongs to the 74ALVCH logic family, an advanced low-voltage CMOS series designed for high-speed digital applications. It complements other 16-bit devices like the 74ALVCH16373 latch by providing edge-triggered storage functionality rather than transparent latching. The family maintains pin compatibility across similar bit-width devices to simplify design reuse.

Replacement Considerations

Public confirmed substitute part numbers include Texas Instruments SN74ALVCH16374 and NXP Semiconductors 74ALVCH16374. These alternatives offer equivalent electrical characteristics and pinout configurations for direct replacement in existing designs.
