74ALVC16601MTD Universal Bus Transceiver 18-Bit Equivalent & Substitute Parts

Part Overview

The 74ALVC16601MTD is an 18-bit universal bus transceiver manufactured by onsemi in a 56-TSSOP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 74ALVC16601MTD operates across a supply voltage range of 1.65V to 3.6V with output drive capabilities of 24mA (high and low), suitable for low-voltage logic applications requiring bidirectional bus switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74ALVC16601MTD is determined by the following critical parameters:

• Logic Function: Universal bus transceiver with 18-bit configuration
• Electrical Specifications: Supply voltage 1.65V ~ 3.6V, output drive 24mA (high and low)
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface mount technology
• Package Compatibility: 56-pin TSSOP or 56-pin SSOP packages

Substitute parts are grouped into two categories based on package type:

1. 56-TSSOP Package (Direct Pin-Compatible): SN74ALVCH162601GR, SN74ALVCH16601DGGR
2. 56-SSOP Package (Functionally Equivalent, Different Footprint): SN74ALVCH162601DL, SN74ALVCH162601DLR, SN74ALVCH16601DL, SN74ALVCH16601DLR

All substitute parts are manufactured by Texas Instruments and carry active product status with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (56-TSSOP Package):

Select SN74ALVCH162601GR or SN74ALVCH16601DGGR when PCB layout and footprint constraints require the original 56-TFSOP (0.240", 6.10mm width) package. Both parts maintain identical package dimensions and pin assignments. SN74ALVCH162601GR offers higher inventory availability (776 Pcs) in tape and reel packaging. SN74ALVCH16601DGGR provides 2600 Pcs in stock with tape and reel configuration. Both are active products with ROHS3 compliance.

For Functionally Equivalent Substitution (56-SSOP Package):

When PCB redesign is acceptable, SN74ALVCH162601DLR or SN74ALVCH16601DLR provide the highest inventory levels (2121 Pcs and 4226 Pcs respectively) in tape and reel packaging. These parts use the 56-BSSOP (0.295", 7.50mm width) package with identical electrical specifications. SN74ALVCH16601DL and SN74ALVCH162601DL are available in tube packaging (1495 Pcs and 995 Pcs respectively) for lower-volume applications.

All Texas Instruments substitutes are active products with ROHS3 compliance and unlimited moisture sensitivity rating, providing long-term supply security compared to the obsolete 74ALVC16601MTD.

Frequently Asked Questions (FAQ)

Q: Can I use SN74ALVCH162601 series parts as direct replacements for 74ALVC16601MTD?

A: Yes, SN74ALVCH162601 series parts are functionally equivalent. However, package selection determines PCB compatibility. The SN74ALVCH162601GR maintains the 56-TSSOP package for direct footprint compatibility. The SN74ALVCH162601DL and SN74ALVCH162601DLR use 56-SSOP packages and require PCB layout modification.

Q: What is the difference between 56-TSSOP and 56-SSOP packages?

A: The 56-TSSOP package has a width of 0.240" (6.10mm), while the 56-SSOP package has a width of 0.295" (7.50mm). Pin pitch and lead configuration differ between these packages. Direct footprint substitution is only possible between identical package types.

Q: Are all substitute parts RoHS compliant?

A: Yes, all Texas Instruments substitute parts (SN74ALVCH series) are ROHS3 compliant. The original 74ALVC16601MTD RoHS status is not specified in available documentation.

Q: What packaging options are available for substitute parts?

A: Texas Instruments offers substitute parts in two packaging formats: Tube (for lower volumes) and Tape & Reel (TR) for higher-volume production. Tube packaging is available for SN74ALVCH162601DL and SN74ALVCH16601DL. Tape and reel packaging is available for all other substitute part numbers.

Q: Do substitute parts have the same electrical performance as the original 74ALVC16601MTD?

A: All substitute parts maintain the same supply voltage range (1.65V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and primary output drive specifications (24mA high and low). Some Texas Instruments variants specify additional output drive ratings (12mA, 12mA) in their documentation, but the primary 24mA specification ensures compatibility.

Q: Which substitute part offers the best inventory availability?

A: SN74ALVCH16601DLR provides the highest inventory level at 4226 Pcs in tape and reel packaging. SN74ALVCH16601DGGR offers 2600 Pcs for the 56-TSSOP package variant.
