74ALVTH162245LRG4 Equivalent & Substitute Parts

Part Overview

The 74ALVTH162245LRG4 is a non-inverting transceiver IC manufactured by Texas Instruments, designed for 2-element, 8-bit-per-element applications with 3-state output capability. This component operates across dual voltage supply ranges (2.3V–2.7V and 3V–3.6V) and is housed in a 48-BSSOP surface mount package. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the 74ALVTH162245LRG4 is determined by strict equivalence across the following critical parameters:

• Logic Function: Transceiver, Non-Inverting configuration with 2 elements and 8 bits per element
• Output Architecture: 3-State output capability
• Electrical Performance: Output current specifications (12mA high, 32mA low) and dual voltage supply ranges (2.3V–2.7V and 3V–3.6V)
• Operating Conditions: Temperature range -40°C to 85°C
• Physical Form Factor: 48-BSSOP surface mount package with 0.295" width (7.50mm)
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The substitute part SN74ALVTH162245LR meets all these criteria and is therefore a direct parametric equivalent. Differences in packaging format (Cut Tape & Digi-Reel versus standard packaging) and product status (Obsolete versus Discontinued) do not affect functional or electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALVTH162245LR is a direct parametric equivalent to the 74ALVTH162245LRG4 and is suitable for applications requiring identical electrical and functional performance. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

The primary distinction between these parts is product lifecycle status: the 74ALVTH162245LRG4 is discontinued at DiGi Electronics, while the SN74ALVTH162245LR is marked as obsolete. For new designs or ongoing production requiring this transceiver function, the SN74ALVTH162245LR provides continuity of supply with no electrical or mechanical compromises. Packaging format differences (Cut Tape & Digi-Reel for the substitute) do not affect circuit performance and represent a standard supply variation.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVTH162245LR be used as a direct replacement for the 74ALVTH162245LRG4?

A: Yes. Both parts are identical in all critical electrical and functional parameters: logic type, element count, bit width, output configuration, current ratings, voltage supply ranges, operating temperature, and package form factor. The parts are pin-compatible and functionally interchangeable.

Q: What is the difference between the two part numbers?

A: The primary differences are packaging format (Cut Tape & Digi-Reel versus standard packaging) and product lifecycle status (Obsolete versus Discontinued). These differences do not affect electrical performance or circuit compatibility.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 74ALVTH162245LRG4 and SN74ALVTH162245LR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching logic function (2-element, 8-bit non-inverting transceiver), output type (3-State), electrical specifications (12mA/32mA output current, dual voltage supply ranges), operating temperature range (-40°C to 85°C), and physical package (48-BSSOP, 7.50mm width). All these parameters are identical between the main part and substitute.

Q: Can this part be used in both 2.3V–2.7V and 3V–3.6V supply applications?

A: Yes. The 74ALVTH162245LRG4 and SN74ALVTH162245LR both support dual voltage supply ranges and can operate across both specified ranges. Circuit design must ensure proper supply voltage selection for the intended application.
