Description

The MAX3042BCUE is a 5V quad RS-485/RS-422 transmitter specifically designed for digital data transmission over twisted-pair balanced lines. It belongs to the MAX3040–MAX3045 family and offers ESD protection of ±10kV using the Human Body Model. This component operates on a single +5V and guarantees device-to-device skew. It is pin-compatible with 'SN75174, '26LS31C, and LTC487. The MAX3042BCUE is hot-swappable for telecom applications and can achieve data rates of up to 20Mbps. For lower data rates at 2.5Mbps and 250kbps, it is slew-rate limited. It also has a low-power shutdown mode, consuming only 2nA in this mode. The operating supply current is 1mA, and it has ±4kV EFT fast transient burst immunity per IEC 1000-4-4. In terms of surge immunity, it meets level 2 standards per IEC 1000-4-5 for unshielded cable models. The MAX3042BCUE is available in ultra-small 16-Pin TSSOP, 16-Pin Narrow SO, and Wide 16-Pin SO packages.
