74ACT1284MTCX

Overview

The Fairchild Semiconductor 74ACT1284MTCX is an IEEE STD 1284 Translation Transceiver IC housed in a 20-TSSOP package. It contains four non-inverting bidirectional buffers and three non-inverting buffers with open-drain outputs featuring high drive capability on the B ports. The device operates within a voltage range of 4.5V to 5.5V.

Feature Summary

• Supports IEEE STD 1284 translation transceiver functions
• Integrates four non-inverting bidirectional buffers
• Includes three non-inverting buffers with open-drain outputs
• Provides high drive capability on the B ports

Applications

• IEEE STD 1284 parallel port interface circuits
• Data bus translation between logic families
• Bidirectional data buffering applications

Procurement Notes

Verify component status as sources indicate this part may be obsolete. Confirm RoHS3 compliance requirements against current project specifications. Ensure the 20-TSSOP package dimensions match the target PCB footprint. Validate that the 4.5V to 5.5V operating voltage aligns with the system power supply rails before procurement.

Selection Notes

Select this component for designs requiring IEEE STD 1284 compatibility. The ACT series offers faster switching speeds compared to standard HC logic. Ensure the application utilizes a 5V supply rail, as the device does not support lower voltages. The open-drain outputs are suitable for wired-OR configurations or interfacing with higher voltage loads.

Part Context

This device belongs to the 74ACT family of advanced CMOS logic devices. It serves as a specialized transceiver for parallel communication standards. The TSSOP package provides a compact surface-mount solution for space-constrained electronic designs requiring robust bidirectional data handling capabilities.

Replacement Considerations

The SN74ACT1284DBR from Texas Instruments is a confirmed substitute part number.
