74ALVC16501MTD Universal Bus Transceiver 18-Bit Equivalent & Substitute Parts

Part Overview

The 74ALVC16501MTD is an 18-bit universal bus transceiver manufactured by onsemi, designed for bidirectional data transmission in logic applications. This component operates across a supply voltage range of 1.65V to 3.6V with output drive capability of 24mA for both high and low states. The part is currently classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74ALVC16501MTD is determined by strict equivalence across the following critical parameters:

• Logic function: Universal bus transceiver architecture
• Bit width: 18-bit configuration
• Output drive current: 24mA high and low
• Supply voltage range: 1.65V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Surface mount
• Package footprint compatibility: 56-pin TFSOP or equivalent pin-compatible packages

The identified substitute parts maintain functional and electrical equivalence while offering active product status from Texas Instruments. Substitutes are grouped by packaging configuration, which affects board-level integration but does not alter electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both Texas Instruments substitutes—SN74ALVCH16501DGGR and SN74ALVCH16501DL—provide active product status with ROHS3 compliance, addressing the obsolescence of the original 74ALVC16501MTD. Selection between these two substitutes depends on packaging requirements:

SN74ALVCH16501DGGR maintains the original 56-TFSOP package footprint (0.240", 6.10mm width) and is supplied in Tape & Reel format, suitable for high-volume automated assembly.

SN74ALVCH16501DL uses a 56-BSSOP package (0.295", 7.50mm width) and is supplied in Tube format. This variant requires board-level layout modification due to the wider package body but remains electrically equivalent.

Both parts maintain identical electrical specifications, supply voltage range, output drive capability, and operating temperature range. Selection should be based on existing PCB layout constraints and procurement volume requirements.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVCH16501DGGR and SN74ALVCH16501DL be used interchangeably on the same PCB?

A: No. While electrically equivalent, these parts use different package footprints. SN74ALVCH16501DGGR uses 56-TFSOP (0.240" width), and SN74ALVCH16501DL uses 56-BSSOP (0.295" width). PCB layout must accommodate the selected package.

Q: What is the primary reason for substituting the 74ALVC16501MTD?

A: The 74ALVC16501MTD is classified as obsolete. Texas Instruments SN74ALVCH16501 variants provide active product status with equivalent electrical performance and improved compliance certifications.

Q: Are the Texas Instruments substitutes pin-compatible with the original onsemi part?

A: Both SN74ALVCH16501 variants maintain the same 18-bit universal bus transceiver function and 56-pin configuration. Pin compatibility depends on package selection: TFSOP maintains the original footprint, while BSSOP requires layout modification.

Q: What packaging format should be selected for automated assembly?

A: SN74ALVCH16501DGGR supplied in Tape & Reel (TR) format is optimized for automated pick-and-place assembly operations.

Q: Do the substitute parts meet current environmental compliance standards?

A: Yes. Both SN74ALVCH16501DGGR and SN74ALVCH16501DL are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Is there a difference in moisture sensitivity between the original and substitute parts?

A: No. All three parts maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations.
