54ACTQ16245W-QV

Overview

The 54ACTQ16245W-QV is a non-inverting bus transceiver manufactured by National Semiconductor. It features two independent elements, each handling eight bits of data with three-state outputs. The device operates within a supply voltage range of 4.5V to 5.5V and utilizes a 48-lead CFP (Ceramic Flat Pack) package. This component belongs to the ACT series, designed for high-speed CMOS logic applications requiring reliable bidirectional data transmission.

Feature Summary

• Non-inverting bus transceiver architecture with dual eight-bit channels
• Three-state output capability for efficient bus line management
• CMOS construction ensuring low power consumption and high noise immunity

Applications

• High-speed data bus systems in industrial control environments
• Memory interface circuits requiring bidirectional data transfer
• Communication modules utilizing standard TTL-compatible logic levels

Procurement Notes

Verify the manufacturer designation as National Semiconductor or its successor entities, such as Texas Instruments, due to corporate acquisitions. Confirm the specific suffix 'QV' indicates the required ceramic flat pack variant and quality grade. Ensure the part number matches the exact 48-lead configuration to avoid compatibility issues with existing PCB footprints.

Selection Notes

Select this component when a non-inverting function is required for dual-channel eight-bit data paths. The ACT series offers faster switching speeds compared to standard LS equivalents. Consider the 48-CFP package constraints regarding thermal dissipation and mounting requirements during system design integration.

Part Context

This part belongs to the 54ACT family of high-speed CMOS logic devices. The 'Q' suffix typically denotes military or extended temperature grade specifications in certain National Semiconductor classifications. The 16245 designation specifically identifies the dual eight-bit transceiver topology within the broader logic IC portfolio.

Replacement Considerations

Check for cross-reference availability from Texas Instruments following the acquisition of National Semiconductor's logic business. Verify pinout compatibility with alternative manufacturers offering similar ACT-series transceivers before substitution.
