74ACT16374DL Equivalent & Substitute Parts

Part Overview

The 74ACT16374DL is a dual 8-bit D-type flip-flop logic integrated circuit manufactured by Texas Instruments. This component functions as a standard edge-triggered storage element with tri-state, non-inverted outputs, operating at a clock frequency of 65 MHz. The device is packaged in a 48-BSSOP surface mount configuration with a 0.295" (7.50mm) width.

The 74ACT16374DL carries a Last Time Buy product status, indicating that Texas Instruments has discontinued active production. This status necessitates identification of equivalent substitute parts to ensure design continuity and procurement availability for new production runs or system updates.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ACT16374DL is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Type: D-Type Flip-Flop (2 elements, 8 bits per element)
• Output Configuration: Tri-State, Non-Inverted
• Trigger Mechanism: Positive Edge
• Clock Frequency: 65 MHz minimum
• Propagation Delay: 8.8 ns @ 5V, 50pF maximum

Electrical Parameters:

• Supply Voltage Range: 4.5V ~ 5.5V
• Output Current Capability: 24 mA (high and low)
• Quiescent Current: 8 µA maximum
• Input Capacitance: 4.5 pF

Physical & Environmental Parameters:

• Package Type: 48-BSSOP (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected Status

Substitute parts must match all parameters listed above without deviation. Packaging format differences (Tube vs. Cut Tape & Digi-Reel) do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The 74ACT16374DLR is the direct functional equivalent of the 74ACT16374DL. Both parts are manufactured by Texas Instruments and share identical electrical, functional, and physical specifications. The primary distinction is product status: the 74ACT16374DL is designated Last Time Buy, while the 74ACT16374DLR maintains Active status.

For new designs or production continuity, the 74ACT16374DLR is the appropriate selection. This part maintains full compliance with ROHS3 and REACH requirements, identical operating temperature range, and equivalent moisture sensitivity classification. The packaging format difference (Cut Tape & Digi-Reel versus Tube) does not affect functional performance and is a procurement consideration only.

Frequently Asked Questions (FAQ)

Q: Can the 74ACT16374DLR be used as a direct replacement for the 74ACT16374DL?

A: Yes. Both parts are electrically and functionally identical. All electrical parameters, timing specifications, output drive capabilities, and environmental ratings are equivalent. The parts are pin-compatible and require no circuit modifications.

Q: What is the difference between the 74ACT16374DL and 74ACT16374DLR?

A: The primary difference is product status and packaging format. The 74ACT16374DL is Last Time Buy (discontinued), while the 74ACT16374DLR is Active.
