74ACT11245PWG4 Equivalent & Substitute Parts

Part Overview

The 74ACT11245PWG4 is a non-inverting transceiver IC with 1 element, 8 bits per element, and 3-state output capability. Manufactured by Texas Instruments in a 24-TSSOP surface mount package, this component operates across a 4.5V to 5.5V supply voltage range with output current ratings of 24mA for both high and low states.

The 74ACT11245PWG4 carries an Obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Substitute Part Grouping Explanation

Substitution of the 74ACT11245PWG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 1
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 24mA, 24mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 24-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount

The 74ACT11245PWR meets all these criteria and serves as a direct functional equivalent. The primary distinction between these parts is packaging format: the main part uses individual packaging, while the substitute is supplied in Tape & Reel (TR) format. Both parts share identical electrical specifications, thermal characteristics, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 74ACT11245PWR is the recommended substitute for the obsolete 74ACT11245PWG4. Both parts maintain identical electrical and thermal specifications, ensuring direct functional compatibility in circuit applications. The 74ACT11245PWR carries Active product status, providing assured long-term availability and supply chain stability compared to the Obsolete status of the original part.

Both parts satisfy ROHS3 compliance and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, meeting environmental and reliability standards for industrial and commercial applications. The substitution involves only a packaging format change from individual to Tape & Reel format, which does not affect electrical performance or mechanical fit within the 24-TSSOP footprint.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT11245PWR be used as a direct replacement for the 74ACT11245PWG4?
