Analog Devices Inc./Maxim Integrated MAX14595ETA+T

Overview

MAX14595ETA+T from Maxim Integrated is a dual-channel, bidirectional logic-level translator optimized for I²C and MDIO bus applications, supporting 0.9V to 5.5V level translation with ultra-low supply currents (7µA VCC, 3µA VL), 17Ω max R_ON, and operation across –40°C to +85°C in an 8-pin TDFN package.

For engineers reviewing the MAX14595ETA+T datasheet, MAX14595ETA+T pinout, MAX14595ETA+T application, or MAX14595ETA+T equivalent, this page delivers verified electrical specs, thermal shutdown behavior, TS-controlled three-state operation, internal 12kΩ pullups, and push-pull/open-drain timing performance up to 8MHz and 4MHz respectively - all critical for portable, battery-powered I²C system design.

Technical Context

The MAX14595ETA+T implements two independent bidirectional transmission gates with accelerator circuitry to reduce rise/fall times, enabling compliant high-speed I²C (up to 4MHz open-drain) and MDIO operation. Its TS input controls both channel enablement and internal pullup activation per powered rail.

It features automatic shutdown when VL exceeds VCC during power sequencing, thermal shutdown at +150°C (10°C hysteresis), and supports asymmetric voltage domains where VL = +0.9V to +3.6V and VCC = +1.65V to +5.5V - with VL ≤ VCC required for normal translation.

Key Specifications

Pinout & Package

MAX14595ETA+T is housed in an 8-pin, 2mm × 2mm TDFN package with exposed pad for thermal dissipation (θ_JA = 162°C/W). Pin assignments are electrically identical between TDFN and WLP variants.

FAQ

What is the maximum capacitive load supported by MAX14595ETA+T in open-drain I²C mode?

The MAX14595ETA+T supports up to 100pF total bus capacitance in open-drain mode while maintaining 4MHz data rate compliance. This is validated per I²C specification and confirmed in the datasheet's timing characteristics table under "Maximum Data Rate (Open-drain operation)" and Figure 2/4 waveforms. Exceeding 100pF may degrade rise time and violate setup/hold margins for standard I²C controllers.

Does MAX14595ETA+T require external pullup resistors for I²C operation?

No - MAX14595ETA+T includes internal 3–12kΩ pullup resistors on both IOVL and IOVCC sides, activated automatically when TS = high and the respective supply (VL or VCC) is present. External pullups are optional and only recommended for high-speed (>4MHz) or high-capacitance (>100pF) I²C buses where tighter rise-time control is needed.

Can MAX14595ETA+T translate between 5V and 0.9V logic levels?

Yes - MAX14595ETA+T supports VCC up to +5.5V and VL down to +0.9V, enabling direct 5V ↔ 0.9V bidirectional translation. However, VL must not exceed VCC during normal operation (per datasheet Note 3); transient VL > VCC is allowed only during startup/shutdown and triggers automatic shutdown to prevent damage.

What happens to MAX14595ETA+T outputs when TS is driven low?

When TS is driven low, MAX14595ETA+T enters three-state shutdown: all I/O pins (IOVL1, IOVL2, IOVCC1, IOVCC2) become high-impedance, and internal pullup resistors are disconnected from both sides. VCC and VL supply currents drop to 0.4µA and 0.1µA respectively, minimizing system power draw during sleep or reset states.

Is MAX14595ETA+T compatible with Fast-mode Plus (Fm+) I²C at 1MHz?

Yes - MAX14595ETA+T fully supports Fast-mode Plus (1MHz) I²C operation in both push-pull and open-drain configurations. Its 8MHz push-pull and 4MHz open-drain maximum data rates exceed Fm+ requirements, and its 17Ω R_ON, low propagation delay (<19ns), and built-in acceleration ensure timing compliance even with 100pF bus loads.
