Substitute Part Grouping Explanation

Substitution of the 74ACT11245PW is determined by strict equivalence across the following critical parameters:

• Logic function: Non-inverting transceiver with 1 element, 8 bits per element
• Output configuration: 3-state output capability
• Electrical performance: 24mA output current (high and low), 4.5V to 5.5V supply voltage range
• Operating temperature range: -40°C to 85°C
• Physical form factor: 24-TSSOP surface mount package with identical dimensions (0.173", 4.40mm width)
• Compliance standards: ROHS3 compliance, MSL Level 1

The 74ACT11245PWR qualifies as a direct substitute based on identical electrical specifications, package geometry, and functional characteristics. The primary distinction is packaging format and product status.
