ADM3202ARNZ

The ADM3202ARNZ is one member of the ADM3202 series.The ADM3202 is available in a 16-lead DIP, narrow and wide SOIC as well as a space saving 20-lead TSSOP package.The ADM3202 is a modification, enhancement and improvement to the AD230AD241 family and its derivatives.It is essentially plug-in compatible and does not have materially different applications.

Features of the ADM3202ARNZ are:(1)460 kbps data rate; (2)specified at +3.3 V; (3)Meets EIA-232E specifications; (4)0.1 F charge pump capacitors; (5)low power shutdown; (6)DIP, SO, SOIC, SSOP and TSSOP package options; (7)upgrade for MAX3222/32 and LTC1385.Capacitors C3 and C4 are used to reduce the output ripple.Their values are not critical and can be increased if desired.Capacitor C3 is shown connected between V+ and VCC. It is also acceptable to connect this capacitor between V+ and GND.

The absolute maximum ratings of the ADM3202ARNZ can be summarized as:(1)Vcc:-0.3V to 6V;(2)ESD rating:<1500 V;(3)operating temperature range:-40 to +85;(4)storage temperature range:65 to +150;(5)lead temperature(soldering,10sec):300;(6)power dissipation N-16:450 mW.This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operation sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.The receivers are inverting level-shifters that accept RS-232 input levels and translate them into 3 V logic output levels.The inputs have internal 5 k pull-down resistors to ground and are also protected against overvoltages of up to ±30 V.Unconnected inputs are pulled to 0 V by the internal 5 k pull-down resistor.This,therefore, results in a Logic 1 output level for unconnected inputs or for inputs connected to GND.
