MAX3243IDBR

The MAX3243IDBR belongs to the MAX3243 family which designed as one kind of 3-V to 5.5-V multichannel RS-232 line driver/receiver that consists of three line drivers, five line receivers, and a dual charge-pump circuit with ±15-kV ESD (HBM) protection pin to pin (serial-port connection pins, including GND). This device matches that needed for the typical serial port used in an IBM PC/AT, or compatible and meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector.

Features of the MAX3243IDBR are:(1)single-chip and single-supply interface for IBM PC/AT serial port;(2)RS-232 bus-pin ESD protection exceeds ±15 kV using human-body model (HBM);(3)meets or exceeds the requirements of TIA/EIA-232-F and ITU v.28 standards;(4)operates with 3-V to 5.5-V Vcc supply;(5)three drivers and five receivers;(6)operates up To 250 kbit/s;(7)designed to transmit at a data rate of 250 kbit/s;(8)low standby current:1A typical;(9)external capacitors:4 * 0.1F;(10)accepts 5-V logic input with 3.3-V supply;(11)always-active noninverting receiver output (ROUT2B);(12)serial-mouse driveability;(13)alternative high-speed pin-compatible device (1 Mbit/s).

The absolute maximum ratings of the MAX3243IDBR can be summarized as:(1)supply voltage range, Vcc:-0.3 V to 6 V;(2)positive output supply voltage range, V+:-0.3 V to 7 V;(3)negative output supply voltage range, V-:0.3 V to -7 V;(4)operating virtual junction temperature:150°C;(5)storage temperature range:-65°C to 150°C;(6)package thermal impedance:62°C/W.
