MAX1484EUB+ Maxim Integrated Products, MAX1484EUB+ Datasheet - Page 7

• Manufacturer Part Number: MAX1484EUB+
• Description: IC TXRX RS485/RS422 10-UMAX
• Manufacturer: Maxim Integrated Products
• Type: Transceiverr

Specifications of MAX1484EUB+

• Number Of Drivers/receivers: 1/1
• Protocol: RS422, RS485
• Voltage - Supply: 4.75 V ~ 5.25 V
• Mounting Type: Surface Mount
• Package / Case: 10-MSOP, Micro10™, 10-uMAX, 10-uSOP

Software-Selectable, Half-/Full-Duplex, Slew-Rate-Limited,
* (MAX1485/MAX1486 only) In half-duplex mode, the driver outputs serve as receiver inputs. The full-duplex receiver inputs (A and B)
will still have a 1/8-unit load, but are not connected to the receiver.

Receiver Output. When RE is low and if A - B ≥ 200mV, RO goes high; if A - B ≤
-200mV, RO goes low.
Half-/Full-Duplex Selector Input. Connect H/F to V
connect to GND for full-duplex mode.
Receiver Output Enable Input. Drive RE low to enable RO; RO is high impedance
when RE is high. For MAX1481 only, drive RE high and DE low to enter the low-
power shutdown mode.
Driver Output Enable Input. Drive DE high to enable driver outputs. These outputs
are high impedance when DE is low.
Driver Input. With DE high, a low on DI forces noninverting output low and invert-
ing output high. Similarly, a high on DI forces noninverting output high and invert-
ing output low.
