Substitute Part Grouping Explanation

Substitution of the 74FCT162H245ATPACT is determined by the following critical parameters:

Electrical Compatibility Parameters:

Logic type: Transceiver, Non-Inverting
Number of elements: 2
Number of bits per element: 8
Output type: 3-State
Output current capability: 24mA minimum (High and Low)
Supply voltage range: 4.5V ~ 5.5V
Operating temperature range: -40°C ~ 85°C

Mechanical Compatibility Parameters:

Package type: 48-TFSOP surface mount
Package dimensions: 0.240" width (6.10mm)

Substitute parts are grouped into two categories:

Category 1 - Parametric Equivalents (Identical Electrical & Mechanical Parameters): Parts that maintain all critical electrical parameters (output current, voltage supply, temperature range) and identical package specifications. These parts are direct functional replacements.

Category 2 - Functional Alternatives (Different Voltage or Current Specifications): Parts that maintain the core transceiver architecture and package but operate at different voltage levels or output current ratings. The SN74LVCR162245DGGR operates at 2.7V ~ 3.6V with reduced output current (12mA), suitable only for low-voltage applications.

Engineering Selection Recommendations

For Direct Replacement (5.5V Supply, 24mA Output Current):

The 74ACT16245DGGR from Texas Instruments is the primary recommended substitute. It maintains identical electrical parameters (24mA output current, 4.5V ~ 5.5V supply) and package specifications while carrying Active product status, ensuring long-term availability and manufacturing support.

The 74FCT162245CTPAG from IDT is an alternative with Active status, offering the same electrical and mechanical specifications. Both parts are suitable for direct substitution in existing designs.

For Extended Availability:

The 74FCT16245ATPAG from IDT provides higher output current capability (32mA High, 64mA Low) while maintaining the same supply voltage range and package. This part is suitable for applications requiring enhanced drive capability and carries Active product status.

For Low-Voltage Applications Only:

The SN74LVCR162245DGGR operates at 2.7V ~ 3.6V with reduced output current (12mA). This part is suitable only for low-voltage system designs and is not compatible with 5.5V supply voltage applications.

Package Consideration:

The 74FCT162245ATPVG uses a 48-BSSOP package (0.295" width) instead of the standard 48-TFSOP (0.240" width). PCB layout modifications are required for this substitution.

Frequently Asked Questions (FAQ)

Q: Can the 74FCT162H245ATPACT be replaced with the SN74LVCR162245DGGR?

A: No, not in standard 5.5V applications. The SN74LVCR162245DGGR operates at 2.7V ~ 3.6V supply voltage, which is incompatible with 5.5V system designs. Use this part only in dedicated low-voltage applications.

Q: What is the difference between 74FCT162245ATPACT and 74FCT16245ATPAG?

A: Both are 74FCT series non-inverting transceivers in 48-TFSOP packages. The 74FCT16245ATPAG provides higher output current (32mA High, 64mA Low) compared to the standard 24mA specification. Both operate at 4.5V ~ 5.5V and -40°C ~ 85°C.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can I use 74FCT162245ATPVG as a direct replacement?

A: The 74FCT162245ATPVG maintains identical electrical parameters but uses a 48-BSSOP package (0.295" width) instead of the standard 48-TFSOP (0.240" width). PCB footprint modifications are required.

Q: Which substitute has the best long-term availability?

A: The 74ACT16245DGGR and 74FCT162245CTPAG both carry Active product status, indicating ongoing manufacturing support. The 74FCT16245ATPAG from IDT also has Active status with the highest current inventory (6679 pcs).

Q: Are there any output current differences I should consider?

A: Yes. Most substitutes maintain 24mA output current. The 74FCT16245ATPAG provides 32mA High and 64mA Low output current, suitable for applications requiring enhanced drive capability. The SN74LVCR162245DGGR provides only 12mA, suitable for low-voltage designs only.
