TL3116CD Equivalent & Substitute Parts

Part Overview

The TL3116CD is a general-purpose comparator IC manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. This device features complementary, push-pull TTL output architecture and operates across single or dual supply voltages (5V ~ 10V or ±2.5V ~ 5V). The TL3116CD is currently in Last Time Buy status, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL3116CD is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Output Type: Complementary, Push-Pull, TTL
• Voltage - Supply, Single/Dual (±): 5V ~ 10V, ±2.5V ~ 5V
• Voltage - Input Offset (Max): 3mV @ ±5V
• Current - Input Bias (Max): 1.1µA @ ±5V
• Current - Output (Typ): 20mA
• CMRR, PSRR (Typ): 100dB CMRR
• Propagation Delay (Max): 12ns

Mechanical Compatibility Requirements:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Number of Elements: 1

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories based on functional type and package configuration:

Group 1 - Direct Functional Equivalent (Same Package): TL3116IDR maintains identical electrical specifications and 8-SOIC packaging, differing only in product status (Active vs. Last Time Buy) and operating temperature range extension.

Group 2 - Functional Equivalents with Enhanced Features (Same Package): MAX9013ESA+ and MAX9013EUA+ provide comparator functionality with integrated latch feature. MAX9013ESA+ maintains 8-SOIC packaging; MAX9013EUA+ uses 8-TSSOP/8-MSOP (8-uMAX/uSOP) packaging. Both feature reduced quiescent current and faster propagation delay, with supply voltage range limited to 4.5V ~ 5.5V.

Parameter Comparison

Engineering Selection Recommendations

TL3116IDR is the primary substitute for TL3116CD. Both devices are manufactured by Texas Instruments with identical electrical specifications and 8-SOIC packaging. TL3116IDR is in Active product status, ensuring long-term availability and supply continuity. The extended operating temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C) provides additional margin for applications requiring wider temperature operation. Quiescent current specification differs marginally (15mA vs. 14.7mA), remaining within acceptable tolerance for general-purpose comparator applications.

MAX9013ESA+ serves as a functional alternative for applications where integrated latch functionality and reduced quiescent current (2.3mA) provide system-level benefits. This device maintains 8-SOIC packaging for direct PCB layout compatibility. Supply voltage range is restricted to 4.5V ~ 5.5V, requiring verification against application requirements. Input bias current is reduced to 0.5µA, and propagation delay is improved to 9ns. Product status is Active with full compliance certifications.

MAX9013EUA+ provides identical electrical performance to MAX9013ESA+ but uses 8-TSSOP/8-MSOP (8-uMAX/uSOP) packaging with reduced footprint (0.118" vs. 0.154" width). This package variant is suitable for space-constrained designs. PCB layout modification is required due to different package geometry. Product status is Active.

Selection between TL3116IDR and MAX9013 variants depends on application requirements: choose TL3116IDR for direct replacement with extended temperature range; choose MAX9013ESA+ for 8-SOIC package with latch feature and lower power consumption; choose MAX9013EUA+ for compact 8-uMAX/uSOP package with identical performance to MAX9013ESA+.

Frequently Asked Questions (FAQ)

Q: Can TL3116IDR directly replace TL3116CD without PCB modification?

A: Yes. TL3116IDR maintains identical 8-SOIC packaging and pin configuration. No PCB layout changes are required. Electrical specifications are equivalent, with TL3116IDR offering extended operating temperature range and Active product status.

Q: What is the key difference between TL3116CD and MAX9013ESA+?

A: MAX9013ESA+ includes integrated latch functionality, whereas TL3116CD is a general-purpose comparator without latch. Supply voltage range differs: MAX9013ESA+ operates 4.5V ~ 5.5V (narrower range), while TL3116CD operates 5V ~ 10V or ±2.5V ~ 5V (wider range). Quiescent current is significantly lower in MAX9013ESA+ (2.3mA vs. 14.7mA). Both use 8-SOIC packaging.

Q: Is MAX9013EUA+ compatible with existing TL3116CD PCB layouts?

A: No. MAX9013EUA+ uses 8-TSSOP/8-MSOP (8-uMAX/uSOP) packaging with different pin spacing and footprint (0.118" width vs. 0.154" width). PCB layout redesign is required. Electrical functionality is equivalent to MAX9013ESA+.

Q: What are the supply voltage constraints when substituting with MAX9013 variants?

A: MAX9013ESA+ and MAX9013EUA+ operate within 4.5V ~ 5.5V supply range. Applications requiring operation at ±2.5V ~ 5V dual supply or single supply above 5.5V must use TL3116IDR instead.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TL3116IDR, MAX9013ESA+, and MAX9013EUA+ are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching TL3116CD compliance status.

Q: Which substitute offers the fastest propagation delay?

A: MAX9013ESA+ and MAX9013EUA+ both feature 9ns maximum propagation delay, compared to 12ns for TL3116CD and TL3116IDR. This 3ns improvement may be significant in high-speed timing-critical applications.

Q: Can I use MAX9013 variants in applications requiring general-purpose comparator operation without latch functionality?

A: Yes. The integrated latch in MAX9013 variants does not prevent general-purpose comparator operation. The latch feature is an additional capability that can remain unused if not required by the application.
