TL3116IPW Equivalent & Substitute Parts

Part Overview

The TL3116IPW is a general-purpose comparator IC manufactured by Texas Instruments, housed in an 8-TSSOP 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 TL3116IPW is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL3116IPW is determined by the following critical parameters:

Primary Substitution Criteria:

• Single comparator element (1 comparator per package)
• Complementary, push-pull TTL output architecture
• Supply voltage compatibility: minimum 5V single supply or ±5V dual supply operation
• Input offset voltage specification of 3mV or better
• Input bias current of 1.1µA or lower
• Output current capability of 20mA or greater
• Propagation delay of 12ns or faster
• Operating temperature range: -40°C to 85°C
• Surface-mount package compatibility (8-pin configurations)
• ROHS3 compliance and MSL Level 1 rating

Substitute Parts Identified:

1. TL3116IPWR (Texas Instruments) – Direct packaging variant with identical electrical specifications
2. MAX9013EUA+T (Analog Devices Inc./Maxim Integrated) – Functionally equivalent with enhanced performance characteristics
3. MAX913EPA+ (Analog Devices Inc./Maxim Integrated) – Through-hole alternative with superior CMRR/PSRR performance
4. MAX913ESA+ (Analog Devices Inc./Maxim Integrated) – Surface-mount alternative with superior CMRR/PSRR performance

Parameter Comparison

Engineering Selection Recommendations

TL3116IPWR is the primary recommended substitute. This part maintains identical electrical specifications and operating characteristics to the TL3116IPW while offering active product status and availability in tape & reel packaging for production environments. Both devices are manufactured by Texas Instruments and share the same 8-TSSOP package footprint, enabling direct PCB compatibility without layout modifications.

MAX9013EUA+T provides an alternative from Analog Devices Inc./Maxim Integrated with enhanced performance metrics, including lower input bias current (0.5µA versus 1.1µA) and higher output current capability (40mA versus 20mA). This device operates within a narrower supply voltage range (4.5V to 5.5V) and features a latch function not present in the TL3116IPW. The 8-uMAX/uSOP package is compatible with 8-TSSOP footprints, though verification of pinout compatibility is required.

MAX913EPA+ and MAX913ESA+ are functionally equivalent alternatives with superior CMRR and PSRR performance (110dB CMRR and 100dB PSRR). These devices feature integrated latch functionality and operate across the full 5V to 10V supply range. MAX913EPA+ is available in through-hole 8-DIP packaging, while MAX913ESA+ is available in surface-mount 8-SOIC packaging. Both support the extended supply voltage range of the original TL3116IPW.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and the -40°C to 85°C operating temperature range of the original device.

Frequently Asked Questions (FAQ)

Q: Can TL3116IPWR be used as a direct replacement for TL3116IPW?

A: Yes. TL3116IPWR is a direct electrical and functional equivalent with identical specifications. The primary difference is packaging format (tape & reel versus tube) and active product status. PCB footprint compatibility is maintained.

Q: What is the key difference between TL3116IPW and MAX913 series comparators?

A: The MAX913 series includes integrated latch functionality not present in the TL3116IPW. Additionally, MAX913EPA+ and MAX913ESA+ offer superior CMRR and PSRR performance (110dB and 100dB respectively versus 100dB CMRR only). The MAX9013EUA+T operates within a narrower supply voltage range (4.5V to 5.5V).

Q: Are package changes required when substituting with MAX913EPA+ or MAX913ESA+?

A: MAX913EPA+ requires through-hole PCB design modifications due to its 8-DIP package. MAX913ESA+ uses an 8-SOIC surface-mount package compatible with surface-mount assembly processes. Both differ from the original 8-TSSOP footprint and require PCB layout verification.

Q: Does MAX9013EUA+T maintain supply voltage compatibility with TL3116IPW?

A: MAX9013EUA+T operates within a narrower supply voltage range of 4.5V to 5.5V, compared to the TL3116IPW range of 5V to 10V (single supply) or ±2.5V to ±5V (dual supply). Applications requiring operation outside the 4.5V to 5.5V window must use alternative substitutes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (TL3116IPWR, MAX9013EUA+T, MAX913EPA+, and MAX913ESA+) maintain ROHS3 compliance and MSL Level 1 rating, matching the environmental and regulatory specifications of the original TL3116IPW.

Q: What is the significance of the latch function in MAX913 series devices?

A: The integrated latch function in MAX913 series comparators provides output state retention capability. This feature is not present in the TL3116IPW. Applications not requiring latch functionality will operate identically; applications requiring this feature must implement external latching circuitry with the TL3116IPW or use MAX913 alternatives.
