SN74ACT1284PW

Specialty Logic Overview

The SN74ACT1284PW is a specialized bus interface integrated circuit manufactured by Texas Instruments. It features seven-bit data transmission capability with three-state outputs, designed for IEEE-1284 parallel port applications. The device operates within a supply voltage range of 4.7 V to 5.5 V and draws a typical operating current of 1.5 mA. It supports surface-mount installation in a TSSOP-20 package and functions reliably across an industrial temperature range from 0°C to +70°C.

Specialty Logic Feature Summary

• Provides seven-bit bidirectional data transfer for parallel communication systems
• Features three-state outputs to facilitate bus line sharing and system flexibility
• Complies with IEEE-1284 standards for enhanced compatibility with peripheral devices

Specialty Logic Applications

• IEEE-1284 compatible parallel port interfaces
• High-speed data bus interconnects
• Parallel printer and peripheral connections

Specialty Logic Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-20 package variant when sourcing. Confirm that the operating voltage requirements align with the 4.7 V to 5.5 V specification. Ensure thermal management meets the 0°C to +70°C operational limits for the intended environment. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit components.

Specialty Logic Selection Notes

Select this component for designs requiring dedicated seven-bit bus interfacing with standard TTL-compatible logic levels. Consider the TSSOP-20 footprint constraints during PCB layout planning. Evaluate power consumption needs against the specified 1.5 mA operating current. Verify that the three-state output configuration matches the system's bus arbitration requirements.

Specialty Logic Part Context

This part belongs to the SN74ACT series of advanced CMOS logic devices from Texas Instruments. It serves as a specialized interface solution distinct from general-purpose buffers or transceivers. The ACT series combines CMOS low power consumption with TTL-compatible input speeds. This specific model addresses niche parallel data transfer needs rather than general logic processing tasks.
