74ALVC2245MTCX Equivalent & Substitute Parts

Part Overview

The 74ALVC2245MTCX is a non-inverting transceiver logic IC manufactured by onsemi, featuring 1 element with 8 bits per element and 3-state output capability. Designed for 3.6V operation, this component is classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts from active manufacturers is essential for design continuity and procurement reliability.

Substitute Part Grouping Explanation

Substitute parts for the 74ALVC2245MTCX are qualified based on 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
Current - Output High, Low: 24mA, 24mA
Voltage - Supply: 1.65V ~ 3.6V
Operating Temperature: -40°C ~ 85°C (TA)
Mounting Type: Surface Mount
Package / Case: 20-TSSOP or 20-TVSOP (0.173", 4.40mm Width)

Substitutes are organized into two categories based on package type: 20-TSSOP (direct footprint match) and 20-TVSOP (compatible footprint with same pitch and pin count).

Engineering Selection Recommendations

All substitute parts listed maintain electrical equivalence with the 74ALVC2245MTCX across supply voltage, output current, and operating temperature ranges. The primary selection criteria are product status and compliance certifications.

For new designs and procurement, parts with Active product status are preferred. All active substitutes carry ROHS3 compliance certification, ensuring regulatory alignment for modern manufacturing environments.

Package selection depends on PCB layout requirements:

20-TSSOP packages (74ALVC245PW,118, SN74ALVC245PW, SN74ALVC245PWR, SN74ALVCH245PW, SN74ALVCH245PWR) provide direct footprint compatibility with the original 74ALVC2245MTCX.
20-TVSOP packages (SN74ALVC245DGVR, SN74ALVCH245DGVR) offer equivalent electrical performance with compatible pin pitch and count, suitable for designs where TVSOP footprints are acceptable.

Packaging type (Tape & Reel, Tube) affects procurement and assembly processes but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use SN74ALVCH245 series parts as direct replacements for 74ALVC2245MTCX?

A: Yes. The 74ALVCH series maintains identical electrical specifications including voltage supply range (1.65V ~ 3.6V), output current (24mA, 24mA), and operating temperature (-40°C ~ 85°C). The series designation change reflects manufacturing improvements while preserving functional compatibility.

Q: What is the difference between 20-TSSOP and 20-TVSOP packages?

A: Both packages share the same pin count (20 pins) and pitch (0.173", 4.40mm width). The primary difference is the package outline. 20-TSSOP is a thin shrink small outline package, while 20-TVSOP is a thin very small outline package. Both are surface mount and electrically equivalent. PCB footprint compatibility depends on your design layout.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed carry ROHS3 compliance certification. The original 74ALVC2245MTCX does not specify RoHS status due to its obsolete classification.

Q: Does packaging type (Tape & Reel vs. Tube) affect electrical performance?

A: No. Packaging type affects only procurement, storage, and assembly handling. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Why is the 74ALVC2245MTCX classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by onsemi. Active substitutes from Texas Instruments and Nexperia provide equivalent functionality with ongoing manufacturing support and compliance certifications.
