TL3116ID Equivalent & Substitute Parts

Part Overview

The TL3116ID 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 a wide supply voltage range of 5V to 10V (single supply) or ±2.5V to 5V (dual supply). The TL3116ID is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Active alternatives with compatible electrical and mechanical specifications are available from both Texas Instruments and Analog Devices Inc./Maxim Integrated.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL3116ID is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Output Type: Complementary, Push-Pull, TTL
• Number of Elements: 1
• Package / Case: 8-SOIC surface-mount form factor
• 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
• Current - Quiescent (Max): 15mA
• CMRR, PSRR (Typ): 100dB CMRR
• Propagation Delay (Max): 12ns
• Operating Temperature: -40°C ~ 85°C

Substitute Categories:

1. Direct Equivalent (Same Package, Same Electrical Specifications): TL3116IDR — Active product status, identical electrical performance, 8-SOIC package.

2. Functional Equivalents with Different Package Options: MAX9013ESA+ (8-SOIC), MAX913CPA+ (8-DIP), MAX913EUA+ (8-TSSOP/8-MSOP) — These devices feature comparator with latch functionality, complementary TTL output, and compatible supply voltage ranges. Package variations accommodate different PCB assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications and Package): Select TL3116IDR. This part maintains full electrical and mechanical compatibility with the TL3116ID while offering active product status, ensuring long-term availability and manufacturing support. Both devices are ROHS3 compliant and carry identical operating temperature ranges.

For Surface-Mount 8-SOIC Applications with Enhanced Performance: MAX9013ESA+ provides faster propagation delay (9ns vs. 12ns), lower quiescent current (2.3mA vs. 15mA), and higher output current capability (40mA vs. 20mA). The latch feature adds functional capability without compromising pin compatibility. Supply voltage range is narrower (4.5V ~ 5.5V), requiring verification against circuit requirements. ROHS3 compliant and active product status.

For Through-Hole 8-DIP Applications: MAX913CPA+ accommodates legacy PCB designs requiring through-hole mounting. Electrical specifications include superior CMRR (110dB) and PSRR (100dB), with slightly extended propagation delay (14ns). Operating temperature range is restricted to 0°C ~ 70°C, requiring thermal environment verification. ROHS3 compliant and active product status.

For Compact Surface-Mount Applications (8-TSSOP/8-MSOP): MAX913EUA+ delivers the smallest footprint (0.118" width) while maintaining full electrical compatibility with the TL3116ID across the complete -40°C ~ 85°C temperature range. CMRR and PSRR performance exceed the original specification. ROHS3 compliant and active product status.

Frequently Asked Questions (FAQ)

Q: Can TL3116IDR be used as a direct replacement for TL3116ID? A: Yes. TL3116IDR is electrically and mechanically identical to TL3116ID, with the same 8-SOIC package, supply voltage range (5V ~ 10V, ±2.5V ~ 5V), and all performance specifications. The primary difference is product status: TL3116IDR is active, while TL3116ID is obsolete.

Q: What is the functional difference between TL3116ID and MAX9013ESA+? A: Both are single-element comparators in 8-SOIC packages with complementary TTL output. MAX9013ESA+ includes integrated latch functionality, faster propagation delay (9ns vs. 12ns), and lower quiescent current (2.3mA vs. 15mA). The supply voltage range is narrower (4.5V ~ 5.5V vs. 5V ~ 10V, ±2.5V ~ 5V).

Q: Are MAX913CPA+ and MAX913EUA+ pin-compatible with TL3116ID? A: No. MAX913CPA+ uses an 8-DIP through-hole package, while MAX913EUA+ uses an 8-TSSOP/8-MSOP surface-mount package. Both differ from the 8-SOIC package of TL3116ID. These parts are functional equivalents, not pin-for-pin replacements.

Q: Which substitute part has the best performance specifications? A: MAX913CPA+ and MAX913EUA+ both offer superior CMRR (110dB) and PSRR (100dB) compared to TL3116ID (100dB CMRR). MAX9013ESA+ provides the fastest propagation delay (9ns) and lowest quiescent current (2.3mA). Selection depends on specific circuit requirements and package constraints.

Q: Do all substitute parts meet RoHS compliance? A: Yes. TL3116IDR, MAX9013ESA+, MAX913CPA+, and MAX913EUA+ are all ROHS3 compliant, matching the compliance status of the original TL3116ID.

Q: What is the operating temperature range for each substitute? A: TL3116IDR, MAX9013ESA+, and MAX913EUA+ operate across -40°C ~ 85°C. MAX913CPA+ has a restricted range of 0°C ~ 70°C, requiring thermal environment verification before selection.

Q: Can MAX9013ESA+ be used in applications requiring ±2.5V ~ 5V dual supply operation? A: No. MAX9013ESA+ supply voltage range is 4.5V ~ 5.5V, which does not support dual supply operation at ±2.5V ~ 5V. Verify circuit supply requirements before substitution.
