AM26LS32AIN Equivalent & Substitute Parts

Part Overview

The AM26LS32AIN is a 0/4 Receiver IC for RS422 and RS423 protocols, manufactured by Texas Instruments in a 16-DIP through-hole package. This part is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production requirements. The AM26LS32AIN operates within a supply voltage range of 4.75V to 5.25V and maintains a receiver hysteresis of 50 mV across an operating temperature range of -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AM26LS32AIN is determined by the following critical parameters:

• Protocol compatibility (RS422, RS423)
• Number of drivers/receivers (0/4 configuration)
• Receiver hysteresis (50 mV nominal)
• Supply voltage range (4.75V ~ 5.25V)
• Operating temperature range (-40°C ~ 85°C)
• Package type (16-DIP through-hole for direct pin compatibility)

Two substitute parts are identified:

1. AM26LS32AIDR - Same base product (AM26LS32) with identical electrical specifications but surface-mount packaging (16-SOIC). This substitute maintains protocol, receiver count, hysteresis, and voltage specifications while offering an active product status.

2. MAX3096CPE+ - Alternative receiver IC from Analog Devices Inc./Maxim Integrated with matching 0/4 receiver configuration and 16-DIP through-hole package. This part maintains package compatibility with the original design while offering active product status.

Parameter Comparison

Engineering Selection Recommendations

AM26LS32AIDR is recommended for designs where surface-mount technology is acceptable. This part maintains identical electrical specifications to the AM26LS32AIN while offering active product status and improved availability. The transition from through-hole to surface-mount packaging requires PCB redesign but eliminates obsolescence risk.

MAX3096CPE+ is recommended for designs requiring through-hole package compatibility with the original AM26LS32AIN footprint. This part preserves the 16-DIP mounting configuration and maintains active product status. The supply voltage range (3V ~ 3.6V) differs from the original specification and requires circuit verification. The operating temperature range (0°C ~ 70°C) is narrower than the original part and may not be suitable for extended temperature applications.

Both substitute parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can AM26LS32AIDR directly replace AM26LS32AIN in existing designs?

A: Electrical substitution is direct due to identical protocol, receiver configuration, hysteresis, and voltage specifications. However, the package change from 16-DIP through-hole to 16-SOIC surface-mount requires PCB redesign and assembly process modification.

Q: What are the key differences between AM26LS32AIDR and MAX3096CPE+?

A: AM26LS32AIDR maintains identical electrical specifications to the original part. MAX3096CPE+ preserves the through-hole package but operates at a different supply voltage range (3V ~ 3.6V versus 4.75V ~ 5.25V) and narrower operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C).

Q: Is MAX3096CPE+ suitable for applications requiring -40°C to 85°C operation?

A: No. MAX3096CPE+ operates only from 0°C to 70°C, making it unsuitable for extended temperature applications requiring the full -40°C to 85°C range of the original AM26LS32AIN.

Q: Does MAX3096CPE+ support RS423 protocol?

A: MAX3096CPE+ supports RS422 and RS485 protocols. RS423 protocol support is not specified for this part. Verify protocol requirements before selection.

Q: What is the inventory status of these substitute parts?

A: AM26LS32AIDR has 8860 pieces in stock. MAX3096CPE+ has 955 pieces in stock. Both parts are classified as active products with ongoing availability.
