CALVCH16245MDLREP Equivalent & Substitute Parts

Part Overview

The CALVCH16245MDLREP is a non-inverting transceiver logic IC manufactured by Texas Instruments, part of the 74ALVCH series. This 48-SSOP surface mount device functions as a 2-element, 8-bit per element transceiver with 3-state output capability, operating across a supply voltage range of 1.65V to 3.6V and temperature range of -55°C to 125°C. The device is currently in active production status and ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the original part becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility demands components from different manufacturers with compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CALVCH16245MDLREP is determined by the following critical parameters:

• Logic Type: Transceiver, Non-Inverting (2 elements, 8 bits per element)
• Output Type: 3-State
• Output Current Capability: 24mA minimum for both high and low states
• Supply Voltage Range: Must support 1.65V minimum to 3.6V maximum
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Package Type: 48-pin surface mount (SSOP, TSSOP, or TFSOP variants acceptable)
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

Substitute parts are grouped by their ability to meet these electrical and mechanical requirements. Parts from different manufacturers (IDT, Nexperia, Renesas) are included when they satisfy the core functional specifications and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The CALVCH16245MDLREP operates with a supply voltage range of 1.65V to 3.6V and temperature range of -55°C to 125°C. All listed substitute parts maintain the core functional specifications of a 2-element, 8-bit non-inverting transceiver with 3-state output and 24mA output current capability.

For applications requiring the full operating temperature range of -55°C to 125°C, the CALVCH16245MDLREP remains the only option among the listed substitutes, as all alternatives are rated to -40°C to 85°C maximum.

For applications operating within -40°C to 85°C temperature range, the following active-status alternatives are available:

74ALVC162245PAG8 (IDT) and 74ALVCH16245DGG,11 (Nexperia) are both in active production status and ROHS3 compliant. The 74ALVCH16245DGG,11 supports a lower minimum supply voltage of 1.2V compared to the IDT part at 2.7V, providing greater voltage flexibility.

Obsolete-status parts (74ALVC16245PAG, 74ALVC16245PAG8, and 74ALVCH16245PAG from Renesas) are available in current inventory but are no longer in active production. These parts are suitable for replacement applications where existing inventory exists but are not recommended for new designs.

Package differences exist between the original CALVCH16245MDLREP (48-BSSOP, 7.50mm width) and all substitute parts (48-TFSOP, 6.10mm width). PCB layout modifications are required when transitioning between these package types.

Frequently Asked Questions (FAQ)

Q: Can I use 74ALVC16245DGG,118 as a direct replacement for CALVCH16245MDLREP?

A: The 74ALVC16245DGG,118 meets the core functional requirements (2-element, 8-bit non-inverting transceiver with 3-state output and 24mA current capability) and is ROHS3 compliant. However, it operates only to -40°C to 85°C, not the full -55°C to 125°C range of the original part. Additionally, the package footprint differs (48-TFSOP vs. 48-BSSOP), requiring PCB layout changes. Use this part only if your application temperature range does not exceed -40°C to 85°C.

Q: What is the difference between 74ALVC and 74ALVCH series parts?

A: Both series are non-inverting transceivers with identical functional specifications in this product category. The primary difference is manufacturer implementation and supply voltage range. The 74ALVCH series from Nexperia supports 1.2V minimum supply voltage, while 74ALVC variants typically support 2.7V minimum. Select based on your minimum supply voltage requirement.

Q: Why do some substitute parts show different output current specifications?

A: The 74ALVC162245PAG8 from IDT lists dual current ratings (12mA, 12mA and 24mA, 24mA), indicating it meets or exceeds the 24mA requirement of the original part. All listed substitutes maintain the minimum 24mA output current capability required for compatibility.

Q: Are obsolete-status parts suitable for new designs?

A: Obsolete-status parts (74ALVC16245PAG, 74ALVC16245PAG8, and 74ALVCH16245PAG) are no longer in active production. While current inventory exists, these parts are not recommended for new designs due to long-term availability risk. Use active-status alternatives (74ALVC162245PAG8 or 74ALVCH16245DGG,11) for new applications.

Q: What packaging considerations apply when switching from CALVCH16245MDLREP to substitute parts?

A: The original part uses 48-BSSOP packaging (0.295" width, 7.50mm), while all listed substitutes use 48-TFSOP packaging (0.240" width, 6.10mm). The TFSOP package is narrower and requires PCB footprint redesign. Pin assignments remain compatible across all parts, but physical board layout must be modified to accommodate the different package dimensions.

Q: Which substitute part offers the widest operating voltage range?

A: The 74ALVCH16245DGG,11 from Nexperia supports 1.2V to 3.6V supply voltage, the widest range among active-status substitutes. This provides maximum voltage flexibility for applications with variable supply conditions.
