SN74HC132DBRG4 Equivalent & Substitute Parts

Part Overview

The SN74HC132DBRG4 is a NAND Gate IC featuring 4 channels with 2 inputs per channel and integrated Schmitt Trigger functionality, packaged in a 14-SSOP surface mount configuration. This logic component operates across a 2V to 6V supply voltage range and is designed for general-purpose digital logic applications requiring noise immunity through Schmitt Trigger input conditioning.

The SN74HC132DBRG4 is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements.

Electrical Parameters (Must Match):

• Logic Type: NAND Gate with 4 channels, 2 inputs per channel
• Schmitt Trigger feature
• Supply voltage range: 2V ~ 6V
• Quiescent current: 2 µA maximum
• Output current: 5.2mA (high and low)
• Input logic levels: Low 0.3V ~ 1.2V, High 1.5V ~ 4.2V
• Propagation delay: 21ns @ 6V, 50pF
• Base product number: 74HC132

Mechanical Parameters (Must Match):

• Surface mount mounting type
• 14-pin package configuration
• RoHS3 compliance
• MSL Level 1

Acceptable Variations:

• Package case dimensions may vary within the 14-pin SSOP/TSSOP family
• Operating temperature range may extend beyond the original specification
• Product status may differ (active vs. discontinued)
• Packaging format (tube vs. tape & reel) does not affect electrical compatibility

Engineering Selection Recommendations

SN74HC132DBR (Texas Instruments)

This part is a parametric equivalent to the SN74HC132DBRG4, maintaining identical electrical specifications and the same 14-SSOP package footprint. The SN74HC132DBR is currently active in production, ensuring supply chain availability. It is packaged in tape & reel format and carries ROHS3 compliance with MSL Level 1 rating. This substitute is suitable for direct replacement in existing designs without PCB layout modifications.

74HC132PW,118 (Nexperia USA Inc.)

This part is a functional equivalent from an alternative manufacturer, meeting all electrical specifications of the SN74HC132DBRG4. The primary difference is the package case: 14-TSSOP (0.173", 4.40mm width) versus the original 14-SSOP (0.209", 5.30mm width). The 74HC132PW,118 offers an extended operating temperature range (-40°C ~ 125°C) compared to the original specification (-40°C ~ 85°C). This part is active in production and ROHS3 compliant with MSL Level 1 rating. PCB layout modifications are required due to the different package footprint.

Frequently Asked Questions (FAQ)

Q: Can the SN74HC132DBR be used as a direct replacement for the SN74HC132DBRG4?

A: Yes. The SN74HC132DBR is electrically and mechanically identical to the SN74HC132DBRG4, with the same 14-SSOP package footprint. No design changes are required.

Q: What is the primary difference between the SN74HC132DBR and 74HC132PW,118?

A: Both parts are electrically equivalent. The key difference is the package case: SN74HC132DBR uses 14-SSOP (0.209" width), while 74HC132PW,118 uses 14-TSSOP (0.173" width). The 74HC132PW,118 also offers an extended operating temperature range to 125°C. PCB layout modifications are necessary if switching to the 74HC132PW,118.

Q: Are all three parts RoHS compliant?

A: Yes. The SN74HC132DBRG4, SN74HC132DBR, and 74HC132PW,118 are all ROHS3 compliant with MSL Level 1 rating.

Q: What does the 14-SSOP and 14-TSSOP package designation mean?

A: Both are 14-pin surface mount packages. SSOP stands for Shrink Small Outline Package with a 0.209" width, while TSSOP stands for Thin Shrink Small Outline Package with a 0.173" width. TSSOP is a more compact variant. Pin configurations are identical, but PCB footprints differ.

Q: Can I use the 74HC132PW,118 if my PCB is designed for the SN74HC132DBRG4?

A: The electrical function is compatible, but the different package footprint (TSSOP vs. SSOP) requires PCB layout modifications. Direct socket replacement is not possible without redesign.

Q: What is the significance of the Schmitt Trigger feature in these parts?

A: The Schmitt Trigger input conditioning provides hysteresis, improving noise immunity in digital logic applications. All three parts include this feature with identical input logic level thresholds.

Q: Are there any compliance or certification differences between these parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry ECCN EAR99 classification. Moisture sensitivity is Level 1 (unlimited) for all parts, indicating no special storage or handling requirements.
