TLC7733IPG4 Equivalent & Substitute Parts

Part Overview

The TLC7733IPG4 is a single-channel power management supervisor IC from Texas Instruments, designed for reset and power-on reset applications. It features push-pull totem pole output configuration with a 2.93V voltage threshold and 1.1ms minimum reset timeout. The device is currently discontinued at DiGi Electronics, with 1034 units available in new original stock. Due to its discontinued status, identifying functionally compatible alternatives is essential for ongoing system design and production planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC7733IPG4 is determined by the following critical parameters:

• Single-channel voltage monitoring capability – All substitutes must monitor exactly one voltage threshold
• Reset/Power-On Reset functionality – Core supervisory function must be preserved
• Voltage threshold compatibility – Threshold must match or be selectable to 2.93V
• Output type compatibility – Push-pull totem pole output or equivalent drive capability
• Reset logic support – Active High/Active Low capability
• Operating temperature range – Must support -40°C ~ 85°C minimum
• RoHS3 compliance – Environmental and regulatory alignment
• Package form factor – Through-hole or surface-mount alternatives acceptable based on design constraints

The TLC7733IP represents a direct package variant substitute (tube packaging vs. standard DIP). The TPS3760A012DYYR represents a functional alternative with different output topology and package form factor, suitable for designs where surface-mount technology and open-drain output are acceptable.

Parameter Comparison

Engineering Selection Recommendations

TLC7733IP – This substitute maintains identical electrical specifications and package form factor as the TLC7733IPG4, with the only difference being packaging format (tube vs. standard DIP). The device is in Last Time Buy status, indicating limited future availability. Selection of this part is appropriate for designs requiring through-hole mounting and identical electrical performance, though long-term supply should be evaluated.

TPS3760A012DYYR – This substitute is currently in Active product status, ensuring ongoing availability and supply chain stability. It maintains single-channel monitoring and reset functionality with ROHS3 compliance. However, critical differences exist: open-drain output topology (vs. push-pull), active-low-only reset logic (vs. active high/active low), 100µs maximum reset timeout (vs. 1.1ms minimum), and surface-mount SOT-23-14 package (vs. through-hole DIP). This part is suitable only for designs where these parameter differences are acceptable and where surface-mount technology is employed. The 0.8V threshold requires external voltage divider configuration to achieve 2.93V monitoring equivalent.

Selection between substitutes depends on design constraints: TLC7733IP for through-hole designs requiring identical specifications with near-term availability; TPS3760A012DYYR for surface-mount designs where output topology and reset timing differences are compatible with system requirements.

Frequently Asked Questions (FAQ)

Q: Can TLC7733IP be used as a direct replacement for TLC7733IPG4?

A: Yes. Both devices share identical electrical specifications, including 2.93V threshold, push-pull totem pole output, active high/active low reset logic, and 1.1ms minimum reset timeout. The only difference is packaging format (tube vs. standard DIP). Through-hole PCB footprints are identical. However, TLC7733IP is in Last Time Buy status, so supply availability is limited.

Q: What are the key differences between TLC7733IPG4 and TPS3760A012DYYR?

A: Four critical differences exist: (1) Output type – TPS3760A012DYYR uses open-drain output instead of push-pull totem pole, requiring external pull-up resistor; (2) Reset logic – TPS3760A012DYYR supports active-low only, not active high/active low; (3) Reset timeout – TPS3760A012DYYR has 100µs maximum vs. 1.1ms minimum, affecting system reset duration; (4) Package – TPS3760A012DYYR is surface-mount SOT-23-14 vs. through-hole 8-DIP. These differences require circuit redesign for compatibility.

Q: Can TPS3760A012DYYR monitor the same 2.93V threshold as TLC7733IPG4?

A: No. TPS3760A012DYYR has a fixed 0.8V threshold. To monitor 2.93V, an external resistive voltage divider must be designed and implemented on the input pin. This adds component count and design complexity compared to the fixed 2.93V threshold of TLC7733IPG4.

Q: Which substitute should I select for a new design?

A: For new designs, TPS3760A012DYYR is recommended due to its Active product status, ensuring long-term supply availability and ongoing manufacturer support. However, this selection requires acceptance of surface-mount technology, open-drain output topology, active-low-only reset logic, and external voltage divider implementation for 2.93V threshold monitoring. If through-hole mounting and identical electrical specifications are mandatory, TLC7733IP is the appropriate choice, with the understanding that supply availability is limited.

Q: Are all three parts RoHS3 compliant?

A: Yes. TLC7733IPG4, TLC7733IP, and TPS3760A012DYYR are all ROHS3 compliant, meeting environmental and regulatory requirements for equivalent component selection.

Q: What is the operating temperature difference between these parts?

A: TLC7733IPG4 and TLC7733IP operate from -40°C ~ 85°C (TA). TPS3760A012DYYR operates from -40°C ~ 125°C (TJ), providing a wider temperature range. This difference may be relevant for applications requiring extended temperature performance.
