MAX3221CAE+

The MAX3221CAE+ is a kind of RS-232 transceiver with autoshutdown. The device is a 1-driver/1-receiver 16-pin SSOP version of the 20-pin MAX3223 (2-driver/2-receiver). It requires only 0.1F capacitors in 3.3 V operation, and can operate from input voltages ranging from +3.0 V to +5.5 V. The typical applications include notebook, subnotebook, and palmtop computers, battery-powered equipment, hand-held equipment, peripherals and printers.

There are some features of the MAX3221CAE+ as follows: (1) 1A supply current achieved with autoshutdown; (2) small 0.1F capacitors; (3) true RS-232 operation from VCC=+3.0 to +5.5 V; (4) meets EIA/TIA-562 specifications down to 2.7 V; (5) guaranteed 120 kbps data rate; (6) 6V/s min guaranteed slew rate; (7) smallest single-supply RS-232 transceiver.

What comes next is about the absolute maximum ratings of the MAX3221CAE+. (1): VCC is from -0.3 to +6 V; (2): V+ is from -0.3 to +7 V; (3): V- is from +0.3 to -7 V; (4): (V+) + |V-| is +13 V; (5): input voltage (R_IN) is ±25 V; (6): output voltage (T_OUT) is ±13.2 V and output voltage (R_OUT, INVALID) is from -0.3 to (VCC + 0.3) V; (7): short-circuit duration (T_OUT) is continuous; (8): continuous power dissipation (TA=+70) is 571 mW and derate 7.14 mW/ above +70; (9): storage temperature is from -65 to +150; (10): operating temperature is from 0 to +70; (11): lead temperature (soldering, 10s) is 300.
