CLVTH16245AIDGVREP Equivalent & Substitute Parts

Part Overview

The CLVTH16245AIDGVREP is a non-inverting transceiver logic IC manufactured by Texas Instruments, designed for 2-element, 8-bit-per-element applications with 3-state output capability. Operating across a 2.7V to 3.6V supply range, this component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLVTH16245AIDGVREP is determined by strict equivalence across the following critical parameters:

• Logic Type: Transceiver, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 8
• Output Type: 3-State
• Current - Output High, Low: 32mA, 64mA
• Voltage - Supply: 2.7V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories based on package compatibility and product status:

Category 1: Direct Package Match (48-TFSOP, 0.173" Width) Parts maintaining identical package dimensions and output current specifications, suitable for direct PCB replacement without layout modification.

Category 2: Alternative Package (48-TFSOP/48-TSSOP, 0.240" Width or 48-SSOP, 0.295" Width) Parts with modified package dimensions but equivalent electrical functionality. These require PCB layout evaluation for footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Direct Package Match)

SN74LVT16245BDGVR and SN74LVTH16245ADGVR are the preferred substitutes, both manufactured by Texas Instruments with active product status. These parts maintain identical package dimensions (48-TFSOP, 0.173" width), output current specifications (32mA, 64mA), and ROHS3 compliance. SN74LVTH16245ADGVR preserves the 74LVTH series designation, while SN74LVT16245BDGVR transitions to the 74LVT series. Both support direct PCB replacement without layout modification.

Secondary Substitutes (Active Status, Alternative Package)

74LVT16245BDGG,118 (Nexperia USA Inc.) and 74LVTH16245BDGG,11 (Nexperia USA Inc.) are active alternatives with modified package dimensions (48-TFSOP, 0.240" width). These parts maintain full electrical equivalence with output current specifications of 32mA, 64mA and ROHS3 compliance. PCB layout evaluation is required to confirm footprint compatibility.

Transitional Substitute (Last Time Buy Status)

74LVT162245MTDX (onsemi) carries Last Time Buy status and presents dual output current specifications (12mA, 12mA; 32mA, 64mA). This part is suitable for applications where supply continuity is not critical but current availability is high. MSL rating of 2 (1 Year) requires controlled storage conditions.

Avoid for New Designs

74LVT16245BDL,112 (Nexperia USA Inc.) carries obsolete status and should not be selected for new production designs despite active inventory levels.

Frequently Asked Questions (FAQ)

Q: Can SN74LVT16245BDGVR directly replace CLVTH16245AIDGVREP on existing PCBs?

A: Yes. Both parts share identical package dimensions (48-TFSOP, 0.173" width), output current ratings (32mA, 64mA), and supply voltage range (2.7V ~ 3.6V). No PCB layout modification is required. The transition from 74LVTH to 74LVT series does not affect functional compatibility for this application.

Q: What is the difference between 74LVT and 74LVTH series designations?

A: Both series meet the same electrical specifications for this transceiver function. The series designation reflects internal design architecture but does not impact substitution eligibility when all electrical and mechanical parameters are equivalent.

Q: Why do some substitutes show different output current specifications?

A: 74LVT162245BDL,118 (NXP) and 74LVT162245MTDX (onsemi) specify 12mA, 12mA output current, which differs from the original 32mA, 64mA specification. These parts are not suitable substitutes for applications requiring the higher output current capability of the original part.

Q: Are package dimension differences critical for substitution?

A: Yes. Parts with 48-TFSOP packages at 0.240" width (74LVT16245BDGG,118, 74LVTH16245BDGG,11) and 48-BSSOP packages at 0.295" width (74LVT162245BDL,118, 74LVT16245BDL,112) require PCB footprint verification before selection. Direct replacement is only guaranteed for parts maintaining the original 0.173" width specification.

Q: What does Last Time Buy status mean for 74LVT162245MTDX?

A: Last Time Buy indicates the manufacturer has announced end-of-life for this part. Current inventory is available, but future procurement may not be possible. This part is suitable only for applications where supply continuity beyond current inventory is not required.

Q: Are all substitutes ROHS3 compliant?

A: All listed substitutes except 74LVT162245BDL,118 (NXP) explicitly state ROHS3 compliance. Compliance status for the NXP part was not provided in the specification data.

Q: What is the significance of MSL rating differences?

A: Most substitutes carry MSL 1 (Unlimited), matching the original part. 74LVT162245MTDX carries MSL 2 (1 Year), requiring controlled storage and limiting shelf life. This affects procurement planning and inventory management for long-term applications.
