74ALVC2245MTC Equivalent & Substitute Parts

Part Overview

The 74ALVC2245MTC is a non-inverting transceiver logic IC manufactured by onsemi, designed for 8-bit bidirectional data transfer with 3-state output capability. Operating across a supply voltage range of 1.65V to 3.6V, this component is classified as obsolete. Due to its discontinued status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production runs and system maintenance.

Substitute Part Grouping Explanation

Substitution eligibility for the 74ALVC2245MTC is determined by strict alignment with the following electrical and mechanical parameters:

Logic Type: Transceiver, Non-Inverting
Number of Elements: 1
Number of Bits per Element: 8
Output Type: 3-State
Voltage - Supply: 1.65V ~ 3.6V
Operating Temperature: -40°C ~ 85°C (TA)
Current - Output High, Low: 24mA, 24mA minimum

Frequently Asked Questions (FAQ)

Q: Can SN74ALVC245DGVR (20-TVSOP package) be used as a direct replacement for 74ALVC2245MTC (20-TSSOP package)?

A: Yes. Both 20-TVSOP and 20-TSSOP packages share identical footprint dimensions (0.173", 4.40mm Width) and are mechanically compatible. Electrical specifications are identical. Package designation differences reflect manufacturing process variations between suppliers without affecting PCB layout or functionality.

Q: What is the difference between 74ALVC and 74ALVCH series substitutes?

A: Both series maintain identical electrical specifications for voltage supply (1.65V ~ 3.6V), operating temperature (-40°C ~ 85°C), output current (24mA), and logic function (non-inverting transceiver, 8-bit, 3-state). The 74ALVCH series represents an enhanced variant from Texas Instruments with improved performance characteristics. Both are functionally equivalent for the 74ALVC2245MTC application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 Compliant status. The original 74ALVC2245MTC does not specify RoHS status due to its obsolete classification.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in three packaging formats: Tape & Reel (TR), Tube, and Tape & Reel with specific supplier designations. All maintain the same 20-pin surface mount footprint (20-TSSOP or 20-TVSOP). Selection depends on production volume requirements and assembly process specifications.

Q: Is the 74ALVC2245MTC still available from the original manufacturer?

A: No. The 74ALVC2245MTC is classified as obsolete. All substitute parts listed are from active manufacturers with current production status and confirmed inventory availability.
