The MAX562 is designed specifically for notebook and palmtop computers that need to transfer data quickly. It runs at data rates up to 230kbps, and has a guaranteed 4V/µs slew rate. This device meets the new EIA/TIA-562 standard that guarantees compatibility with RS-232 interfaces. The MAX562 has low-power shutdown and keep-awake modes. In keep-awake mode, the transmitters are disabled but all receivers are active, allowing unidirectional communication. In shutdown mode, the entire chip is disabled and all outputs are in a high-impedance state. The MAX562 is available in a standard 28-pin SO package, and in a smaller footprint shrink small-outline package (SSOP).
The MAX562 is a serial interface designed for notebook and palmtop computers, supporting data rates up to 230 kbps and a guaranteed 4 V/µs slew rate. It operates from a 2.7 V to 5.25 V supply and is available in 28‑pin SO and SSOP packages.
The device includes low‑power shutdown and keep‑awake modes, three drivers, five receivers, and on‑chip charge‑pump converters that generate +5.8 V and –5.2 V supplies. Detailed electrical characteristics, pin configurations, and timing diagrams are provided for designers.
| Operating Supply Voltage | 2.7 V to 5.25 V |
|---|---|
| Slew Rate | 4 V/µs (guaranteed) |
| Drivers / Receivers | 3 Drivers, 5 Receivers |
| Shutdown Supply Current | ≈1 µA |
It operates from 2.7 V to 5.25 V.
The device contains three drivers and five receivers.
In shutdown mode the chip is disabled and all outputs are high‑impedance; in keep‑awake mode the transmitters are disabled while the receivers remain active.
