SN74LVC06APWRE4 Equivalent & Substitute Parts

Part Overview

The SN74LVC06APWRE4 is a 6-channel inverter logic IC with open-drain outputs manufactured by Texas Instruments in a 14-TSSOP surface mount package. This part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives. The device operates across a 1.65V to 3.6V supply voltage range with a maximum propagation delay of 4.6ns at 3.3V with 50pF load. Equivalent substitutes maintain the same logic function, package form factor, and core electrical characteristics while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters: logic type (inverter), circuit count (6 channels), input count (1), open-drain output feature, package form factor (14-TSSOP), and mounting type (surface mount). All substitute parts listed maintain these core specifications. Secondary parameters including supply voltage range, quiescent current, output current, input logic levels, and propagation delay are provided for application-specific compatibility verification. Parts are grouped by manufacturer and product status to facilitate selection based on availability and supply chain requirements.

Engineering Selection Recommendations

SN74LVC06APWR and SN74LVC06APWT are direct Texas Instruments substitutes with identical electrical specifications and active product status. Both are available in Tape & Reel packaging with significantly higher inventory levels than the discontinued SN74LVC06APWRE4. These parts are preferred for applications requiring exact parameter matching and single-source manufacturer continuity.

74LCX06MTCX and MC74LCX06DTR2G are functionally equivalent alternatives from Fairchild Semiconductor and onsemi respectively. Both operate within a 2V to 3.6V supply range with slightly elevated quiescent current (10 µA versus 1 µA) and marginally longer propagation delay (3.7ns versus 4.6ns). Operating temperature range is reduced to -40°C to 85°C. These parts are suitable for applications where the original supply voltage minimum of 1.65V is not required and where the temperature range limitation is acceptable.

74LVC06APW-Q100J from NXP USA Inc. offers extended supply voltage range (1.2V to 5.5V) and improved propagation delay (2.5ns at 5V). Higher output current capability (32mA) and elevated quiescent current (10 µA) are provided. This part is appropriate for applications requiring broader voltage compatibility or enhanced output drive capability.

74LVC06APW,118 from NXP Semiconductors maintains active status with the highest inventory availability. Detailed electrical specifications are not provided in the data set; verification against application requirements is necessary before selection.

All substitute parts maintain ROHS3 compliance, 14-TSSOP package form factor, and surface mount mounting type. Selection should prioritize product status, inventory availability, and specific application voltage and temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC06APWR directly replace SN74LVC06APWRE4?

A: Yes. SN74LVC06APWR is a direct substitute with identical electrical specifications, same 14-TSSOP package, and active product status. The primary difference is packaging format: SN74LVC06APWRE4 is supplied in an unspecified format while SN74LVC06APWR is supplied in Tape & Reel. Both are Texas Instruments products with matching voltage supply range (1.65V to 3.6V), quiescent current (1 µA), output current (24mA), and propagation delay (4.6ns at 3.3V, 50pF).

Q: What are the key differences between 74LVC and 74LCX series?

A: Both series are 6-channel inverters in 14-TSSOP packages with open-drain outputs. The 74LVC series (Texas Instruments, NXP) operates at 1.65V to 3.6V supply voltage with 1 µA quiescent current. The 74LCX series (Fairchild, onsemi) operates at 2V to 3.6V with 10 µA quiescent current and slightly longer propagation delay (3.7ns versus 4.6ns). The 74LVC series supports lower minimum supply voltage and lower quiescent current consumption.

Q: Is 74LVC06APW-Q100J compatible with the original application?

A: Compatibility depends on application requirements. 74LVC06APW-Q100J maintains the same logic function, package, and mounting type. It offers extended supply voltage range (1.2V to 5.5V) and faster propagation delay (2.5ns at 5V). However, quiescent current is elevated to 10 µA, and operating temperature range is -40°C to 125°C. Verify that the application can tolerate these parameter variations before selection.

Q: Why do some substitute parts have reduced operating temperature range?

A: 74LCX06MTCX and MC74LCX06DTR2G operate to 85°C maximum, compared to 125°C for the original SN74LVC06APWRE4. This is a design characteristic of the 74LCX series. Applications requiring operation above 85°C must use 74LVC series alternatives (SN74LVC06APWR, SN74LVC06APWT, or 74LVC06APW-Q100J).

Q: What packaging options are available?

A: SN74LVC06APWR and SN74LVC06APWT are supplied in Tape & Reel format. 74LCX06MTCX and 74LVC06APW-Q100J are supplied in Bulk. MC74LCX06DTR2G is supplied in Tape & Reel. Select packaging based on assembly process requirements and order quantity.

Q: Are all substitute parts RoHS compliant?

A: SN74LVC06APWR, SN74LVC06APWT, 74LCX06MTCX, and MC74LCX06DTR2G are ROHS3 compliant. Compliance status for 74LVC06APW,118 and 74LVC06APW-Q100J is not specified in the provided data. Verify RoHS compliance with the manufacturer or distributor if required for your application.
