SN74ACT564PW Equivalent & Substitute Parts

Part Overview

The SN74ACT564PW is a Logic category D-Type Flip Flop integrated circuit manufactured by Texas Instruments, featuring 1 element with 8-bit positive edge triggering in a 20-TSSOP surface mount package. This part is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design requirements and production continuity. The device operates at 90 MHz clock frequency with tri-state inverted output configuration and is suitable for digital logic applications requiring edge-triggered flip-flop functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74ACT564PW is determined by the following critical parameters: package type (20-TSSOP surface mount), logic family (74ACT series), element configuration (1 element, 8-bit), trigger type (positive edge), voltage supply range (4.5V ~ 5.5V), and output drive capability (24 mA).

The substitute parts are grouped into two categories:

Direct Equivalent (Packaging Variant): SN74ACT564PWR maintains identical electrical specifications and base product number (74ACT564) with only packaging format difference (Tape & Reel vs. Tube).

Functional Alternatives (Output Configuration Variants): MC74ACT374DTR2G and MC74ACT574DTR2G are manufacturer-recommended substitutes that share the same package, mounting type, voltage supply, output drive capability, and operating temperature range. These alternatives differ in output polarity (non-inverted vs. inverted) and clock frequency specifications, requiring circuit-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

SN74ACT564PWR is the primary substitute for SN74ACT564PW. Both parts share identical electrical specifications, base product number, and package configuration. The only difference is packaging format (Tape & Reel vs. Tube). SN74ACT564PWR maintains active product status and is ROHS3 compliant, making it the direct replacement for discontinued inventory.

MC74ACT374DTR2G and MC74ACT574DTR2G are functional alternatives when output polarity inversion is not a circuit requirement. Both onsemi parts are active products with ROHS3 compliance. MC74ACT374DTR2G offers higher clock frequency (160 MHz) and faster propagation delay (10 ns), while MC74ACT574DTR2G provides intermediate performance (100 MHz, 11 ns propagation delay). Both alternatives feature non-inverted tri-state output configuration and higher quiescent current (8 µA vs. 4 µA).

Selection between these alternatives depends on circuit requirements for output polarity and performance specifications. All substitute parts maintain identical supply voltage range, output drive capability, operating temperature range, and surface mount 20-TSSOP package compatibility.

Frequently Asked Questions (FAQ)

Q: Can SN74ACT564PWR directly replace SN74ACT564PW in production?

A: Yes. SN74ACT564PWR is electrically identical to SN74ACT564PW with matching specifications for clock frequency, propagation delay, output type, and all electrical parameters. The only difference is packaging format (Tape & Reel vs. Tube). Both are 20-TSSOP surface mount packages with identical pinout and functionality.

Q: What is the key difference between SN74ACT564PW and MC74ACT374DTR2G?

A: The primary difference is output polarity. SN74ACT564PW features tri-state inverted output, while MC74ACT374DTR2G features tri-state non-inverted output. Additionally, MC74ACT374DTR2G operates at higher clock frequency (160 MHz vs. 90 MHz) with faster propagation delay (10 ns vs. 10.5 ns) and higher quiescent current (8 µA vs. 4 µA). Circuit design must account for output polarity requirements.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All parts listed use the 20-TSSOP (0.173", 4.40mm Width) surface mount package with identical pinout and footprint. PCB layout compatibility is maintained across all substitutes.

Q: What is the difference between MC74ACT374DTR2G and MC74ACT574DTR2G?

A: Both parts feature non-inverted tri-state output and identical package configuration. MC74ACT374DTR2G operates at 160 MHz clock frequency with 10 ns propagation delay, while MC74ACT574DTR2G operates at 100 MHz with 11 ns propagation delay. Both maintain 24 mA output drive capability and 4.5V ~ 5.5V supply voltage range.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. SN74ACT564PWR, MC74ACT374DTR2G, and MC74ACT574DTR2G are all ROHS3 compliant. All parts are also REACH unaffected and classified under ECCN EAR99.

Q: What is the product status of each substitute part?

A: SN74ACT564PWR, MC74ACT374DTR2G, and MC74ACT574DTR2G are all active products with current manufacturing and distribution availability. SN74ACT564PW is discontinued at DiGi Electronics, making active substitutes necessary for ongoing production.
