74FCT162244ATPVCG4

Overview

The Texas Instruments 74FCT162244ATPVCG4 is a 16-bit bus transceiver with 3-state outputs, belonging to the FCT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features non-inverting polarity. The device provides high-level output current of -24 mA and low-level output current of 24 mA, with a static current of 5 uA. It exhibits a propagation delay of 4.8 ns at 5 V and has a power dissipation rating of 1 W. Packaged in a 48-pin SSOP (TSSOP-48) format, it supports surface mount installation and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides 16-bit bidirectional data transmission capability with three-state output control for efficient bus management.
• Features CMOS technology within the FCT logic family to ensure compatibility with standard digital systems.
• Offers robust drive strength with specified high and low-level output currents suitable for direct interface applications.

Applications

• High-speed data buffering in computer systems
• Clock driver circuits requiring precise timing
• Memory module interfacing

Procurement Notes

Verify the complete part number including the suffix CG4 to confirm RoHS compliance status as indicated in manufacturer documentation. Ensure the package type matches the required 48-pin SSOP footprint for PCB layout compatibility. Cross-reference the specific revision level against the latest datasheet to confirm electrical characteristics remain unchanged. Confirm that the ordering information aligns with the intended volume requirements and lead time constraints provided by authorized distributors.

Selection Notes

Select this component when a 16-bit wide bus interface with three-state isolation is required. The FCT logic family offers speed-performance trade-offs suitable for moderate-frequency digital designs. Consider the 4.5V to 5.5V operating range to ensure compatibility with existing system power rails. The 48-pin SSOP package is appropriate for space-constrained applications where surface-mount technology is preferred over through-hole alternatives.

Part Context

This device is part of the broader 74FCT162244 product line manufactured by Texas Instruments. It shares functional similarities with other 16-bit bus transceivers but is distinguished by its specific pinout, package configuration, and electrical parameters defined by the FCT specification. The CG4 suffix typically denotes environmental compliance attributes rather than functional differences from the base model.

Replacement Considerations

The 74FCT162244ATPACT is identified as a related component within the same functional category. Verify pin-to-pin compatibility and electrical specifications before substitution. Note that the ATPACT variant may have different packaging or lifecycle status compared to the ATPVCG4 version.
