CD74HC30PW NAND Gate IC Equivalent & Substitute Parts

Part Overview

The CD74HC30PW is a single-channel 8-input NAND gate logic IC manufactured by Texas Instruments in a 14-TSSOP surface mount package. This part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. The 74HC30 logic family provides standard NAND gate functionality across multiple manufacturers, with several direct equivalents available in active production status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC30PW is determined by strict equivalence across the following parameters: logic type (NAND gate), number of circuits (1), number of inputs (8), voltage supply range (2V to 6V), package type (14-TSSOP), and mounting type (surface mount). All substitute parts listed maintain identical electrical specifications for supply voltage, input/output logic levels, quiescent current, and output drive capability. Propagation delay specifications may vary slightly between manufacturers but remain within acceptable tolerances for standard logic applications. Operating temperature range and RoHS compliance status are provided for each substitute to support design and procurement decisions.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring immediate availability, CD74HC30PWR (Texas Instruments, Tape & Reel) provides direct electrical and mechanical equivalence with active production status and identical propagation delay specifications. This part maintains the same manufacturer lineage as the discontinued CD74HC30PW.

For automotive-grade applications requiring AEC-Q100 qualification, 74HC30PW-Q100J (Nexperia USA Inc.) is the appropriate selection. This part meets automotive standards while maintaining electrical compatibility, though the operating temperature minimum is -40°C rather than -55°C.

MC74HC30ADTR2G (onsemi) is available in active production with full electrical compatibility. The propagation delay specification is 30ns at 6V and 50pF, which is 8ns slower than the original part but remains within standard logic timing tolerances for most applications.

74HC30PW,118 (NXP Semiconductors) is available in bulk packaging. Complete electrical specifications are not provided in the available data; verification of compatibility parameters is necessary before selection.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can CD74HC30PWR directly replace CD74HC30PW? A: Yes. CD74HC30PWR is electrically and functionally identical to CD74HC30PW. The only difference is packaging format: CD74HC30PWR is supplied in Tape & Reel format while CD74HC30PW was supplied in Tube format. Both are Texas Instruments products with identical electrical specifications.

Q: What is the difference between standard and automotive-grade 74HC30 parts? A: The 74HC30PW-Q100J carries AEC-Q100 automotive qualification and is suitable for automotive applications. The operating temperature range is -40°C to 125°C compared to -55°C to 125°C for standard parts. All electrical parameters remain equivalent.

Q: Is the MC74HC30ADTR2G propagation delay difference significant? A: MC74HC30ADTR2G specifies 30ns propagation delay compared to 22ns for other substitutes. This 8ns difference is within standard logic timing tolerances and is acceptable for most applications. Critical timing applications should verify this specification against system requirements.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance status, ensuring compatibility with RoHS-regulated manufacturing environments and supply chains.

Q: What packaging options are available for 74HC30 substitutes? A: Substitute parts are available in three packaging formats: Tape & Reel (CD74HC30PWR, 74HC30PW-Q100J, MC74HC30ADTR2G), Bulk (74HC30PW,118), and Tube (original CD74HC30PW). Selection depends on procurement volume and assembly line requirements.

Q: Can I use 74HC30PW,118 as a direct substitute? A: 74HC30PW,118 is electrically compatible based on the 74HC30 base product number. However, complete electrical specifications are not provided in available data. Verification of all critical parameters with the manufacturer or distributor is recommended before design implementation.
