• Positive edge trigger functionality
• 48-pin TFSOP package with 0.240" (6.10mm) width
• Surface mount mounting type
• Operating temperature range of -40°C to 85°C

Electrical Compatibility Criteria:

• Supply voltage range (must accommodate or overlap with 4.5V ~ 5.5V)
• Output drive capability (24mA minimum for both high and low states)
• Quiescent current specifications
• Input capacitance characteristics

Compliance Criteria:

• RoHS3 compliance
• MSL rating of 1 (Unlimited)

Substitute parts are grouped into two categories: manufacturer-recommended active alternatives and direct functional equivalents from the same series.

Parameter Comparison

Engineering Selection Recommendations

SN74ALVCH162374GR (Manufacturer-Recommended Primary Substitute)

The SN74ALVCH162374GR is the manufacturer-recommended substitute for the 74FCT162374ATPACT. This part maintains identical functional architecture (dual 8-bit D-type flip-flop with tri-state, non-inverted outputs) and package form factor (48-TFSOP). The SN74ALVCH162374GR is an active product with ROHS3 compliance and MSL rating of 1.

Key differences: The SN74ALVCH162374GR operates at a lower supply voltage range (1.65V ~ 3.6V) compared to the original part (4.5V ~ 5.5V). Output drive current is reduced to 12mA per output versus 24mA. Quiescent current is significantly lower at 40 µA. These characteristics make the SN74ALVCH162374GR suitable for applications where lower power consumption and lower voltage operation are acceptable.

74FCT162374ATPAG (Direct Series Equivalent)

The 74FCT162374ATPAG is a direct functional equivalent within the 74FCT series, manufactured by Renesas Electronics. This part maintains identical electrical specifications including supply voltage (4.5V ~ 5.5V), output drive current (24mA), and quiescent current (500 µA). The 48-TFSOP package and operating temperature range are identical. This part is classified as obsolete.

74FCT163374CPAG and 74FCT163374CPAG8 (Series Variants)

The 74FCT163374CPAG and 74FCT163374CPAG8 are active products from IDT within the 74FCT series. Both maintain the dual 8-bit D-type flip-flop architecture and 48-TFSOP package. These parts operate at 2.7V ~ 3.6V supply voltage. Detailed electrical specifications for output drive current and quiescent current are not provided in the available data. These parts are active products.

Selection Guidance Based on Product Status and Compliance:

For new designs or systems requiring long-term supply assurance, the SN74ALVCH162374GR is recommended as the primary choice due to its active product status and full ROHS3 compliance. This part is suitable when the lower supply voltage range and reduced output drive current are compatible with system requirements.

For applications requiring exact electrical compatibility with the original 74FCT162374ATPACT (5V supply, 24mA output drive), the 74FCT162374ATPAG provides direct functional equivalence, though both the original and this substitute are classified as obsolete.

The 74FCT163374CPAG and 74FCT163374CPAG8 are active alternatives within the 74FCT series, suitable for applications operating at 2.7V ~ 3.6V supply voltage.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALVCH162374GR be used as a direct replacement for the 74FCT162374ATPACT in existing designs?

A: The SN74ALVCH162374GR provides functional equivalence in terms of flip-flop architecture, output configuration, and package form factor. However, the supply voltage range differs (1.65V ~ 3.6V versus 4.5V ~ 5.5V), and output drive current is reduced (12mA versus 24mA). Direct substitution is possible only if the system design accommodates these electrical differences.

Q: What is the primary difference between the 74FCT162374ATPACT and the 74FCT163374CPAG?

A: Both parts are dual 8-bit D-type flip-flops in the 48-TFSOP package. The primary difference is supply voltage range: the 74FCT162374ATPACT operates at 4.5V ~ 5.5V, while the 74FCT163374CPAG operates at 2.7V ~ 3.6V. The 74FCT162374ATPACT is obsolete; the 74FCT163374CPAG is active.

Q: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts listed (SN74ALVCH162374GR, 74FCT162374ATPAG, 74FCT163374CPAG, and 74FCT163374CPAG8) are available in the 48-TFSOP package with 0.240" (6.10mm) width, matching the original 74FCT162374ATPACT package specification.

Q: Which substitute part has the lowest power consumption?

A: The SN74ALVCH162374GR has the lowest quiescent current at 40 µA, compared to 500 µA for the 74FCT162374ATPACT and 74FCT162374ATPAG. This makes the SN74ALVCH162374GR suitable for power-sensitive applications.

Q: Are all substitute parts RoHS3 compliant?
