MAX913EPA Equivalent & Substitute Parts

Part Overview

The MAX913EPA is a single-channel comparator with integrated latch functionality, manufactured by Analog Devices Inc./Maxim Integrated. This linear integrated circuit operates with complementary TTL output and is housed in an 8-pin DIP package suitable for through-hole mounting. The device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The MAX913EPA provides TTL-compatible output levels with latch capability for applications requiring signal comparison and state retention.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MAX913EPA is determined by the following critical parameters:

Primary Substitution Criteria:

• Single-channel comparator architecture (Number of Elements: 1)
• TTL-compatible output (Complementary, TTL output type)
• Supply voltage range compatibility (5V ~ 10V operation)
• Input offset voltage performance (≤ 2mV @ ±5V)
• Input bias current specification (≤ 5µA @ ±5V)
• Output current capability (20mA typical)
• Propagation delay performance (≤ 14ns maximum)
• Operating temperature range (-40°C ~ 85°C)
• Through-hole mounting in 8-pin DIP package
• RoHS3 compliance and MSL Level 1 rating

Substitute Categories:

1. Direct Package Equivalent (MAX913EPA+): Identical electrical specifications and 8-DIP through-hole package. Differs only in product status (Active vs. Obsolete) and packaging format (Tube vs. standard).

2. Functional Equivalents with Package Variation (AD8561ANZ, TL3116IPWR): General-purpose comparators with TTL-compatible output, 8-pin packages, and comparable electrical performance. These parts maintain core functionality but may have different package types (DIP vs. TSSOP) and mounting methods (through-hole vs. surface mount).

Parameter Comparison

Engineering Selection Recommendations

MAX913EPA+ (Direct Equivalent): This part is the primary substitute for the MAX913EPA. It maintains identical electrical specifications, supply voltage range, and 8-DIP through-hole package configuration. The MAX913EPA+ is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant with MSL Level 1 rating. Selection of MAX913EPA+ is recommended for designs requiring exact electrical and mechanical compatibility with the original MAX913EPA specification.

AD8561ANZ (Functional Equivalent): The AD8561ANZ is a general-purpose comparator with TTL-compatible output in an 8-DIP through-hole package. It provides faster propagation delay (9.8ns vs. 14ns) and lower input bias current (6µA vs. 5µA). The AD8561ANZ supports an extended supply voltage range (3V ~ 10V, ±1.5V ~ 5V) compared to the MAX913EPA (5V ~ 10V). Input offset voltage is higher at 7mV versus 2mV. This part is suitable for applications where the latch function is not required and where the extended voltage range or improved propagation delay provides system benefits. ROHS3 compliance and MSL Level 1 rating are maintained.

TL3116IPWR (Functional Equivalent): The TL3116IPWR is a general-purpose comparator manufactured by Texas Instruments in an 8-TSSOP surface-mount package. It provides comparable propagation delay (12ns) and superior input bias current performance (1.1µA). The TL3116IPWR operates at 5V or ±5V supply voltages. This part requires PCB redesign for surface-mount implementation and is not suitable for through-hole mounting applications. Selection is appropriate for new designs utilizing surface-mount assembly processes where the improved input bias current and compact package size provide design advantages. ROHS3 compliance and MSL Level 1 rating are maintained.

Frequently Asked Questions (FAQ)

Q: Can MAX913EPA+ be used as a direct replacement for MAX913EPA? A: Yes. The MAX913EPA+ is electrically and mechanically identical to the MAX913EPA. Both parts feature the same 8-DIP through-hole package, supply voltage range (5V ~ 10V), input offset voltage (2mV @ ±5V), and propagation delay (14ns maximum). The primary difference is product status: MAX913EPA+ is in active production while MAX913EPA is obsolete. Substitution requires no circuit modifications.

Q: What is the key functional difference between MAX913EPA and AD8561ANZ? A: The MAX913EPA includes integrated latch functionality, while the AD8561ANZ is a general-purpose comparator without latch capability. Both devices provide TTL-compatible output and operate within the -40°C to 85°C temperature range. The AD8561ANZ offers faster propagation delay (9.8ns vs. 14ns) and extended supply voltage range (3V ~ 10V, ±1.5V ~ 5V). If latch functionality is required, MAX913EPA+ is the appropriate substitute. If latch is not needed, AD8561ANZ may provide performance advantages.

Q: Can TL3116IPWR replace MAX913EPA in existing through-hole PCB designs? A: No. The TL3116IPWR uses an 8-TSSOP surface-mount package, while MAX913EPA uses an 8-DIP through-hole package. Direct PCB substitution is not possible without redesigning the board layout and footprint. The TL3116IPWR is suitable only for new designs utilizing surface-mount assembly processes.

Q: Are all substitute parts RoHS3 compliant? A: Yes. MAX913EPA+, AD8561ANZ, and TL3116IPWR are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. All parts meet the same environmental and regulatory compliance standards as the original MAX913EPA.

Q: Which substitute part has the best input offset voltage performance? A: The MAX913EPA and MAX913EPA+ both specify 2mV input offset voltage @ ±5V, which is superior to AD8561ANZ (7mV @ 5V) and TL3116IPWR (3mV @ ±5V). If input offset voltage performance is critical to system accuracy, MAX913EPA+ is the recommended substitute.

Q: What is the propagation delay ranking among all parts? A: AD8561ANZ provides the fastest propagation delay at 9.8ns maximum, followed by TL3116IPWR at 12ns, and MAX913EPA/MAX913EPA+ at 14ns maximum. Selection depends on timing requirements of the specific application.

Q: Can AD8561ANZ operate at ±5V supply voltage like MAX913EPA? A: Yes. The AD8561ANZ supports dual supply operation at ±1.5V ~ 5V, which includes ±5V operation. However, the single supply range is 3V ~ 10V. Verify that your specific application's supply voltage configuration is compatible with the AD8561ANZ specifications.
