74VCX162240MTDX Equivalent & Substitute Parts

Part Overview

The 74VCX162240MTDX is a 4-element, 4-bit inverting buffer with 3-state output logic integrated circuit manufactured by onsemi. This device operates across a supply voltage range of 1.4V to 3.6V and is housed in a 48-TSSOP package. The product is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74VCX162240MTDX are identified based on the following critical parameters that determine functional equivalence:

• Logic Type: Buffer, Inverting (4 Element, 4 Bit per Element)
• Output Type: 3-State
• Operating Temperature Range: -40°C ~ 85°C (TA)
• Package / Case: 48-TFSOP or compatible 48-pin surface mount packages
• Voltage - Supply: Minimum 1.4V support with upper range of 3.6V

The substitute parts listed below maintain these core functional parameters. Variations in output current capability and supply voltage range do not preclude substitution when the application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both SN74ALVCH16240DGGR and SN74ALVCH16240DL are active products manufactured by Texas Instruments and carry ROHS3 compliance certification, providing regulatory advantage over the obsolete 74VCX162240MTDX.

SN74ALVCH16240DGGR maintains the identical 48-TFSOP package footprint as the original part, enabling direct PCB layout compatibility without redesign. This part is supplied in Tape & Reel packaging.

SN74ALVCH16240DL uses a 48-BSSOP package with a wider body (0.295" versus 0.240"), requiring PCB layout verification before implementation. This part is supplied in Tube packaging.

Both substitute parts provide higher output current capability (24mA versus 12mA) and operate within a minimum supply voltage of 1.65V, which is compatible with applications designed for the original 1.4V minimum specification.

Frequently Asked Questions (FAQ)

Q: Can SN74ALVCH16240DGGR be used as a direct replacement for 74VCX162240MTDX?

A: Yes. Both parts share identical logic configuration (4-element, 4-bit inverting buffer with 3-state output), operating temperature range (-40°C to 85°C), and package footprint (48-TFSOP). The substitute part offers higher output current and active product status.

Q: What is the difference between SN74ALVCH16240DGGR and SN74ALVCH16240DL?

A: The primary difference is package type. SN74ALVCH16240DGGR uses 48-TFSOP (0.240" width), while SN74ALVCH16240DL uses 48-BSSOP (0.295" width). PCB layout compatibility must be verified for the wider BSSOP package. Both parts are electrically identical.

Q: Are there supply voltage compatibility concerns when substituting?

A: The original 74VCX162240MTDX operates from 1.4V minimum. Both substitute parts operate from 1.65V minimum. Applications requiring operation below 1.65V require verification that the substitute part meets system requirements.

Q: Do the substitute parts have better compliance status?

A: Yes. Both SN74ALVCH16240DGGR and SN74ALVCH16240DL carry ROHS3 compliance certification. The original 74VCX162240MTDX compliance status is not specified in available documentation.

Q: What packaging options are available for the substitute parts?

A: SN74ALVCH16240DGGR is supplied in Tape & Reel (TR) packaging. SN74ALVCH16240DL is supplied in Tube packaging. Selection depends on assembly process requirements and order quantity.
