74FCT16823CTPVCG4 Equivalent & Substitute Parts

Part Overview

The 74FCT16823CTPVCG4 is a dual 9-bit D-type flip-flop logic integrated circuit manufactured by Texas Instruments in the 74FCT series. This component features positive edge triggering, tri-state non-inverted outputs, and master reset functionality. The device is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility across core electrical parameters including propagation delay, output drive capability, and supply voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

74FCT162823CTPVG8 (Renesas Electronics Corporation)

This substitute maintains full functional compatibility with the 74FCT16823CTPVCG4 across all core logic parameters. Both devices operate within the 4.5V to 5.5V supply range and share identical operating temperature specifications. The 74FCT162823CTPVG8 is currently in active production status, ensuring long-term availability. ROHS3 compliance and REACH unaffected status align with regulatory requirements. The primary distinction is the Moisture Sensitivity Level (MSL 3 versus MSL 1), which requires controlled storage conditions during 168-hour periods. This device is suitable for applications where propagation delay at higher capacitive loads (300pF) is acceptable.

SN74ABT16823DL (Texas Instruments)

This substitute provides superior performance characteristics while maintaining functional equivalence. The SN74ABT16823DL operates in the same 74-series logic family with identical core specifications. It delivers faster propagation delay (5.5ns at 5V, 50pF) compared to the main part (6ns), making it suitable for timing-critical applications. Output drive capability matches the original specification (32mA high, 64mA low). The device maintains MSL 1 rating, eliminating moisture sensitivity constraints. Active product status ensures continued availability. This substitute is recommended for direct replacement in existing designs without circuit modification.

Both substitutes are ROHS3 compliant and carry EAR99 export classification, maintaining regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can the 74FCT162823CTPVG8 be used as a direct replacement for the 74FCT16823CTPVCG4?

A: Yes. Both devices share identical functional specifications including D-type flip-flop architecture, 2 elements with 9 bits per element, positive edge triggering, and tri-state non-inverted outputs. Supply voltage (4.5V ~ 5.5V) and operating temperature range (-40°C ~ 85°C) are identical. The 56-BSSOP package ensures mechanical compatibility. The primary consideration is the MSL 3 rating, which requires controlled storage conditions during 168-hour periods.

Q: What is the performance difference between the SN74ABT16823DL and the 74FCT16823CTPVCG4?

A: The SN74ABT16823DL exhibits faster propagation delay at 5.5ns (50pF load) compared to 6ns for the original part. Output drive capability is identical (32mA high, 64mA low). Both devices operate within the same supply voltage and temperature ranges. The SN74ABT16823DL belongs to the 74ABT series rather than 74FCT, but maintains full functional compatibility for this application.

Q: Are there packaging format differences between these substitutes?

A: Yes. The 74FCT16823CTPVCG4 and SN74ABT16823DL are supplied in Tube packaging, while the 74FCT162823CTPVG8 is supplied in Tape & Reel (TR) format. Both packaging formats are compatible with standard surface mount assembly processes. Selection depends on production volume and assembly equipment capabilities.

Q: What does MSL 3 (168 Hours) mean for the 74FCT162823CTPVG8?

A: MSL 3 indicates the component must be stored in controlled humidity conditions and used within 168 hours of exposure to ambient conditions above specified moisture levels. This requires implementation of moisture control procedures during storage and handling. The SN74ABT16823DL and original 74FCT16823CTPVCG4 carry MSL 1 rating, which permits unlimited storage without moisture control requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. The 74FCT16823CTPVCG4, 74FCT162823CTPVG8, and SN74ABT16823DL are all ROHS3 compliant and carry REACH unaffected status, meeting current environmental and regulatory requirements.

Q: Which substitute should be selected for new designs?

A: The SN74ABT16823DL is recommended for new designs due to active product status, superior propagation delay performance, and MSL 1 rating eliminating moisture sensitivity constraints. The 74FCT162823CTPVG8 is suitable as an alternative when Renesas sourcing is preferred or when propagation delay at higher capacitive loads is acceptable.
