SN74HC04PW Equivalent & Substitute Parts

Part Overview

The SN74HC04PW is a 6-channel inverter logic IC manufactured by Texas Instruments in 14-TSSOP surface mount packaging. This part is discontinued at DiGi Electronics but remains available through inventory channels. The SN74HC04PW performs basic logic inversion functions across six independent channels, making it fundamental to digital circuit design where signal inversion is required. Finding equivalent and substitute parts is necessary due to the discontinued status and to identify functionally compatible alternatives from active manufacturers.

Substitute Part Grouping Explanation

Substitution for the SN74HC04PW is determined by strict equivalence across the following parameters: logic type (inverter), number of circuits (6), number of inputs (1), package type (14-TSSOP), mounting type (surface mount), and compliance certifications (ROHS3, REACH Unaffected). Substitute parts must maintain identical or superior electrical performance within the specified voltage supply range (2V to 6V) and output current ratings (5.2mA minimum for both high and low states).

Substitutes are grouped into two categories:

Category 1: Direct 74HC04 Equivalents – Parts maintaining identical specifications including operating temperature range (-40°C to 85°C), quiescent current (2µA), and propagation delay (16ns @ 6V, 50pF). These provide pin-for-pin compatibility with no design modifications required.

Category 2: Enhanced 74HC04 Variants – Parts with improved specifications such as extended operating temperature range (-40°C to 125°C), reduced propagation delay (13-15ns @ 6V, 50pF), or superior quiescent current performance (1µA). These are fully compatible substitutes with performance advantages.

Category 3: 74HCU04 Series – Parts using the unbuffered 74HCU04 logic family with different input logic level thresholds (0.3V to 1.2V low, 1.7V to 4.8V high versus 0.5V to 1.8V low, 1.5V to 4.2V high for standard 74HC04). These require circuit-level verification of input signal compatibility but maintain identical package, pin count, and output specifications.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement with no design changes: Select SN74HC04PWR (Texas Instruments, active status) or MM74HC04MTCX (onsemi, active status). Both maintain identical electrical specifications to the SN74HC04PW with matching operating temperature range and propagation delay. SN74HC04PWR is available in Cut Tape & Digi-Reel packaging; MM74HC04MTCX is available in Tape & Reel.

For improved performance with extended temperature range: Select MC74HC04ADTR2G (onsemi) or 74HC04PW,118 (Nexperia USA Inc.). Both are active products with ROHS3 compliance. MC74HC04ADTR2G offers superior quiescent current (1µA) and faster propagation delay (13ns). 74HC04PW,118 provides extended operating temperature to 125°C with 14ns propagation delay.

For cost-optimized alternatives: 74HC04T14-13 (Diodes Incorporated) and 74HCU04T14-13 (Diodes Incorporated) are active products with extended temperature range to 125°C. Note that 74HCU04T14-13 uses the unbuffered logic family with different input thresholds and requires verification of input signal compatibility in the target circuit.

For applications requiring higher output current on low state: MM74HCU04MTCX (onsemi) provides 7.8mA output low current versus standard 5.2mA, with active product status and ROHS3 compliance.

All recommended substitutes maintain ROHS3 compliance, REACH Unaffected status, and identical 14-TSSOP package dimensions. Selection should prioritize active product status and availability from the specified packaging format required by your assembly process.

Frequently Asked Questions (FAQ)

Q: Can I use 74HCU04 series parts as direct replacements for 74HC04?

A: 74HCU04 parts are pin-compatible and functionally equivalent inverters in the same 14-TSSOP package. However, they use unbuffered logic with different input logic level thresholds (0.3V to 1.2V low, 1.7V to 4.8V high) compared to standard 74HC04 (0.5V to 1.8V low, 1.5V to 4.2V high). Verify that your input signal voltage levels are compatible with the 74HCU04 thresholds before substitution.

Q: What is the difference between SN74HC04PW and SN74HC04PWR?

A: Both are Texas Instruments 74HC04 inverters with identical electrical specifications. The primary difference is packaging format: SN74HC04PW is supplied in Tube packaging (now discontinued), while SN74HC04PWR is supplied in Cut Tape & Digi-Reel format (active status). Electrical performance and pin configuration are identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH Unaffected status, matching the compliance profile of the original SN74HC04PW.

Q: Which substitute offers the fastest propagation delay?

A: 74HCU04T14-13 (Diodes Incorporated) provides the fastest propagation delay at 12ns @ 6V, 50pF. MC74HC04ADTR2G (onsemi) offers 13ns. Both are active products with full compliance certifications.

Q: Can I substitute based on operating temperature range alone?

A: No. While extended temperature range (-40°C to 125°C) is available in MC74HC04ADTR2G, 74HC04PW,118, 74HC04T14-13, and 74HCU04T14-13, substitution must also verify matching logic type, circuit count (6 channels), input count (1 per channel), package type (14-TSSOP), and output current specifications (minimum 5.2mA for both high and low states).

Q: What packaging formats are available for active substitutes?

A: Active substitutes are available in three packaging formats: Cut Tape & Digi-Reel (SN74HC04PWR, MM74HCU04MTCX), Tape & Reel (MC74HC04ADTR2G, 74HC04PW,118, 74HC04T14-13, 74HCU04T14-13), and Tube (original SN74HC04PW, now discontinued). Verify your assembly process requirements before selecting a substitute.
