General Description

Features

The MAX3040–MAX3045 is a family of 5V quad RS-

485/RS-422 transmitters designed for digital data trans-

mission over twisted-pair balanced lines. All transmitter

outputs are protected to ±±0ꢀV using the ꢁuman ꢂody

Model. In addition the MAX3040–MAX3045 withstand

±4ꢀV per IꢃE ±000-4-4 ꢃlectrical ꢄast Transient/ꢂurst

Stressing. The MAX3040/MAX3043 (250ꢀbps) and the

MAX304±/MAX3044 (2.5Mbps) are slew-rate limited

transmitters that minimize ꢃMI and reduce reflections

caused by improperly terminated cables, thus allowing

error-free transmission.

♦ —ot-Swmppmbꢃe for Teꢃecou Appꢃicmtions

♦ Up to 21ꢂbps Dmtm Rmte (ꢂAX3142ꢀ/ꢂAX3145ꢀ)

♦ Sꢃew-Rmte Liuiteꢁ (Dmtm Rmtes mt 2.5ꢂbps mnꢁ

2510bps)

The MAX3040–MAX3045 feature a hot-swap capability

that eliminates false transitions on the data cable during

power-up or hot insertion. The MAX3042ꢂ/MAX3045ꢂ

are optimized for data transfer rates up to 20Mbps, the

MAX304±/MAX3044 for data rates up to 2.5Mbps, and

the MAX3040/MAX3043 for data rates up to 250ꢀbps.

The MAX3040–MAX3045 offer optimum performance

when used with the MAX3093ꢃ or MAX3095 5V quad

differential line receivers or MAX3094ꢃ/MAX3096 3V

quad differential line receivers.

The MAX3040–MAX3045 are ꢃSD-protected pin-compat-

ible, low-power upgrades to the industry-standard

‘SN75±74 and ‘DS26LS3±E. They are available in space-

saving TSSOP, narrow SO, and wide SO pacꢀages.
