Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74VHC541N is determined by the following critical parameters:

• Logic function: Non-inverting buffer with identical element and bit configuration (1 element, 8 bits per element)
• Output architecture: 3-state output capability
• Electrical performance: Output current rating of 8mA for both high and low states
• Supply voltage compatibility: 2V to 5.5V operating range
• Package format: 20-DIP through-hole mounting with 0.300" (7.62mm) pitch
• Pin configuration: Identical pinout required for direct substitution

The SN74AHC541N from Texas Instruments meets all these substitution criteria, providing functional equivalence with the 74VHC541N while offering extended operating temperature range and active product status.
