TLC352IPW Equivalent & Substitute Parts

Part Overview

The TLC352IPW is a dual differential comparator IC manufactured by Texas Instruments, housed in an 8-TSSOP surface mount package. This device features CMOS, MOS, and open-drain TTL output configurations with a wide supply voltage range of 1.4V to 16V (single) or ±0.7V to ±8V (dual). The TLC352IPW is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity.

Engineering Selection Recommendations

TLC352IPWR (Texas Instruments): This is the manufacturer-recommended substitute for the obsolete TLC352IPW. It maintains identical electrical specifications, supply voltage range, and output characteristics. The only difference is packaging format (Tape & Reel vs. tube packaging). This part is active and ROHS3 compliant, making it the preferred choice for direct replacement in existing designs without circuit modification.

TS393IPT (STMicroelectronics): This cross-manufacturer substitute is compatible with the TLC352IPW in applications where the lower minimum supply voltage (2.7V vs. 1.4V) is acceptable. The TS393IPT offers superior quiescent current performance (25µA vs. 400µA) and an extended operating temperature range (-40°C ~ 125°C). Both parts are ROHS3 compliant and MSL Level 1. Selection of the TS393IPT is appropriate when power efficiency or wider temperature operation is required, provided the application does not require operation below 2.7V supply voltage.

Frequently Asked Questions (FAQ)

Q: Can TLC352IPWR be used as a direct replacement for TLC352IPW? A: Yes. The TLC352IPWR is the manufacturer-recommended substitute with identical electrical specifications, supply voltage range, and output configuration. The parts differ only in packaging format (Tape & Reel vs. tube). No circuit modifications are required.

Q: What are the key differences between TLC352IPW and TS393IPT? A: Both devices are dual comparators in 8-TSSOP packages with 20mA output current and 5mV input offset voltage. The TS393IPT has a higher minimum supply voltage (2.7V vs. 1.4V), lower quiescent current (25µA vs. 400µA), and extended operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C). The TLC352IPW supports TTL output; the TS393IPT does not.

Q: Are all substitute parts ROHS3 compliant? A: Yes. The TLC352IPW, TLC352IPWR, and TS393IPT are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute should be selected for low-voltage applications below 2.7V? A: The TLC352IPWR must be used for applications requiring supply voltages below 2.7V, as it maintains the original 1.4V minimum supply voltage specification. The TS393IPT is not suitable for such applications.

Q: What is the impact of quiescent current differences between TLC352IPW and TS393IPT? A: The TS393IPT consumes significantly less quiescent current (25µA vs. 400µA). This difference is relevant only in battery-powered or ultra-low-power applications where standby current is a design constraint. For standard applications, both parts are functionally equivalent.
