Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74HC163PW,118 is determined by strict adherence to the following parameters:

• Logic Function: Binary counter, 4-bit, up-counting direction
• Electrical Interface: Synchronous positive-edge trigger, synchronous reset
• Supply Voltage: 2 V to 6 V operating range
• Package Compatibility: 16-TSSOP surface mount package with identical pinout
• Compliance: ROHS3 compliance and MSL Level 1 rating

All substitute parts listed maintain these core parameters. Variations in count rate (35 MHz to 55 MHz), operating temperature range, and product status are noted but do not prevent functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the 74HC163PW,118, the following selection criteria apply based on product status and compliance:

Active Status Parts (Recommended for new designs):

• SN74HC163IPWRG4Q1 (Texas Instruments, automotive-qualified, AEC-Q100)
• SN74HC163PWR (Texas Instruments, active status)

Last Time Buy Status (Suitable for existing production):

• SN74HC163PW (Texas Instruments, tube packaging)
• SN74HC163PWT (Texas Instruments, tape & reel packaging)

Obsolete Status (Limited availability):

• MC74HC163ADTG (onsemi, tube packaging, extended temperature range to -55°C)
• MC74HC163ADTR2G (onsemi, extended temperature range to -55°C)

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating. The automotive-qualified variant (SN74HC163IPWRG4Q1) is suitable for applications requiring AEC-Q100 certification. Selection should prioritize active-status parts for long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can SN74HC163PWR be used as a direct replacement for 74HC163PW,118? A: Yes. Both parts share identical logic function, 4-bit binary counter architecture, synchronous positive-edge trigger, synchronous reset, 2 V to 6 V supply voltage range, and 16-TSSOP package. The SN74HC163PWR is active status with current manufacturing support.

Q: What is the difference between the onsemi MC74HC163ADTG and Texas Instruments SN74HC163PWR variants? A: Both are functionally equivalent 4-bit binary counters in 16-TSSOP packages. The MC74HC163ADTG operates at 35 MHz with extended temperature range (-55°C to 125°C) and is obsolete. The SN74HC163PWR operates at 36 MHz with -40°C to 85°C range and is active status.

Q: Is the automotive-qualified SN74HC163IPWRG4Q1 suitable for non-automotive applications? A: Yes. The SN74HC163IPWRG4Q1 meets AEC-Q100 automotive qualification standards and is fully compatible with standard industrial and commercial applications. It provides additional reliability assurance through automotive-grade testing.

Q: Does packaging type (tube vs. tape & reel) affect electrical performance? A: No. Packaging type affects only handling, storage, and assembly processes. Electrical specifications and functional performance are identical between tube and tape & reel variants of the same part number base.

Q: Can I substitute an obsolete part with an active-status part in existing designs? A: Yes, provided the active-status substitute meets the electrical and mechanical parameters specified in your design. Active-status parts offer superior long-term supply assurance and are preferred for design updates.
