74ACT16245MTD Equivalent & Substitute Parts

Part Overview

The 74ACT16245MTD is a non-inverting transceiver IC manufactured by onsemi, featuring 2 elements with 8 bits per element and 3-state output capability in a 48-TSSOP package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part operates within a 4.5V to 5.5V supply voltage range with output current capability of 24mA for both high and low states, suitable for logic-level signal buffering and bus interface applications.

Substitute Part Grouping Explanation

Substitution for the 74ACT16245MTD is determined by strict equivalence across the following critical parameters:

• Logic type: Transceiver, Non-Inverting
• Element and bit configuration: 2 elements, 8 bits per element
• Output type: 3-State
• Output current: 24mA high and low
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature: -40°C ~ 85°C
• Mounting type: Surface Mount
• Package compatibility: 48-pin TSSOP or SSOP variants

Substitute parts are grouped into three categories:

Direct Manufacturer Substitutes maintain identical package specifications (48-TSSOP) with active or current product status from alternative manufacturers.

Similar Manufacturer Substitutes share all electrical parameters but use alternative package variants (48-SSOP) with different physical dimensions, requiring PCB layout verification.

Parametric Equivalents belong to the 74FCT series, maintaining all functional and electrical specifications while offering different product lifecycle status and manufacturer options.

Parameter Comparison

Engineering Selection Recommendations

For new designs and procurement, 74ACT16245DGGR (Texas Instruments) is the primary recommendation. This part maintains identical electrical and package specifications to the 74ACT16245MTD while offering active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

74ACT16245DLR provides an alternative from Texas Instruments with active status and ROHS3 compliance. The 48-SSOP package differs physically from the original 48-TSSOP, requiring PCB layout verification before implementation. This option remains suitable for applications where package footprint adjustment is feasible.

74ACT16245DL is available with higher inventory but carries Last Time Buy status, indicating limited future availability. Selection of this part should be restricted to applications requiring immediate procurement with no long-term production continuity requirements.

74FCT162245CTPAG (IDT) offers active product status with identical specifications and is suitable for applications where manufacturer diversification is required. The 74FCT series represents a parametric equivalent with proven compatibility across the specified electrical and functional parameters.

74FCT162245ATPAG (Renesas) shares all functional specifications but carries obsolete status, limiting its suitability to legacy system support or inventory management scenarios.

Frequently Asked Questions (FAQ)

Q: Can 74ACT16245DGGR directly replace 74ACT16245MTD without PCB modification?

A: Yes. The 74ACT16245DGGR maintains identical package specifications (48-TSSOP), pinout, and electrical parameters. Direct substitution on existing PCBs is possible without layout changes.

Q: What is the difference between 48-TSSOP and 48-SSOP packages?

A: The 48-TSSOP package has a 0.240" (6.10mm) width, while the 48-SSOP package has a 0.295" (7.50mm) width. These are different physical footprints requiring separate PCB designs. Verify footprint compatibility before selecting 48-SSOP variants.

Q: Are all substitute parts ROHS3 compliant?

A: Texas Instruments variants (74ACT16245DGGR, 74ACT16245DLR, 74ACT16245DL) and Renesas 74FCT162245ATPAG are ROHS3 compliant. IDT 74FCT162245CTPAG compliance status is not specified in available documentation.

Q: Why is 74ACT16245DL marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has announced end-of-life for this part. Existing inventory may be available, but future procurement is not guaranteed. Use only for immediate requirements or legacy system maintenance.

Q: Can 74FCT162245 series parts substitute for 74ACT16245 series?

A: Yes, as parametric equivalents. The 74FCT162245ATPAG and 74FCT162245CTPAG maintain all critical electrical and functional specifications (logic type, element/bit configuration, output type, current ratings, voltage range, and temperature range). Series differences do not affect functional compatibility for the specified parameters.

Q: What is the significance of MSL Level 1?

A: MSL Level 1 (Unlimited) indicates unlimited shelf life without moisture baking requirements. All substitute parts listed maintain this specification, ensuring consistent handling and storage procedures.
