The MAX560/MAX561 are the first +3.3V-powered devices to implement the EIA/TIA-562 standard, which guarantees interoperability with RS-232 interfaces. The MAX560/MAX561 are guaranteed to operate with a +3.0V power supply at a 20kbits/sec data rate while maintaining ±3.7V EIA/TIA-562 signal levels.
The MAX560/MAX561 include four line drivers, five receivers, a shutdown mode, and a receiver-enable input. An on-board charge-pump voltage converter converts the +3.3V input to the ±6.6V needed to comply with the EIA/TIA-562 output levels. The MAX560 has an active-low shutdown and an active-high receiver enable. In shutdown mode, two receivers are active, allowing unidirectional communication for peripheral monitoring. The MAX561 has an active-high shutdown and an active-low receiver enable. In shutdown mode, all receivers are in a high-impedance, three-state mode.
The MAX560/MAX561 are available in a standard 28-pin wide small outline (SO) package and a 28-pin shrink small outline package (SSOP), which requires 40% of the board space of the SO package. Each operates with four 1µF capacitors, further reducing board space.
