Analog Devices Inc./Maxim Integrated MAX3024EUD

Overview

MAX3024EUD from Maxim Integrated is a quad-channel unidirectional logic-level translator enabling 100Mbps data transfer between +1.2V to +1.8V low-voltage domains (VL side) and +1.65V to +3.6V higher-voltage systems (VCC side). It features dual enable inputs (EN/EN), operates over –40°C to +85°C, and reduces supply current to 0.03µA (VCC) and 0.1µA (VL) in tri-state mode. Used in portable communication devices and SPI/MICROWIRE interfaces where voltage domain isolation and fast edge integrity are critical.

For engineers reviewing the MAX3024EUD datasheet, MAX3024EUD pinout, MAX3024EUD application, or MAX3024EUD equivalent, key selection considerations include its 4-channel VL→VCC-only translation direction, TSSOP-14 package with dual active-high/active-low enables, guaranteed 100Mbps operation at VL ≥ 1.8V, ultra-low disabled current, and compatibility with CMOS loads up to 40pF.

Technical Context

The MAX3024EUD implements a one-shot accelerator output architecture that activates only during signal transitions, minimizing static power while delivering sub-4ns rise/fall times (C_IOVCC = 40pF). Its input thresholds are defined as 1/3×VL and 2/3×VL on the VL side, and 1/3×VCC and 2/3×VCC on the VCC side - ensuring robust noise margins across operating voltages.

Unlike bidirectional variants (e.g., MAX3023), the MAX3024EUD supports only VL→VCC translation: I_VL1–IVL4 accept low-voltage inputs and drive O_VCC1–OVCC4 outputs referenced to VCC. EN and EN pins provide independent control of tri-state behavior per Table 2, with internal pullup (EN) and pulldown (EN) circuitry in the TSSOP package.

Key Specifications

FAQ

What is the maximum guaranteed data rate for MAX3024EUD at VL = 1.2V?

The MAX3024EUD guarantees 80Mbps operation when VL is below 1.8V, including at 1.2V. This is specified in Table 1 of the datasheet under "Data Rate" and confirmed in timing characteristics with C_IOVL = 15pF. At VL = 1.2V, propagation delays remain within 6–7ns, supporting reliable 80Mbps signaling in low-power portable systems.

Does MAX3024EUD support bidirectional translation like MAX3023EUD?

No, the MAX3024EUD is strictly unidirectional: it translates only from VL-side inputs (I VL1–I VL4) to VCC-side outputs (O VCC1–O VCC4). Unlike the bidirectional MAX3023EUD, it cannot pass signals from VCC to VL. This is explicitly defined in the "Pin Description-MAX13015/MAX13016/MAX13017/MAX3024–MAX3028" section and Ordering Information table.

How do the EN and EN pins interact in MAX3024EUD?

In the MAX3024EUD TSSOP package, EN (pin 5) is active-high and EN (pin 6) is active-low. Per Table 2, both must be asserted correctly for normal operation: EN = VL (high) and EN = GND (low). If either is violated, all I/Os enter tri-state. Internal pullup (EN) and pulldown (EN) ensure defined states when left unconnected.

Can MAX3024EUD be used with VL > VCC during power-up?

Yes - the MAX3024EUD tolerates VL > VCC during startup/shutdown without damage, as noted in Note 1 of the Absolute Maximum Ratings. However, normal operation requires VL ≤ VCC − 0.4V. This feature simplifies power sequencing in systems where low-voltage rails ramp before high-voltage supplies.

What is the recommended decoupling for MAX3024EUD?

Per Applications Information, both VCC (pin 12) and VL (pin 13) must be bypassed to GND with 0.1µF ceramic capacitors placed as close as possible to their respective pins. This minimizes supply ripple and prevents data errors at 100Mbps. No additional bulk capacitance is required unless system-level noise analysis indicates otherwise.
