MAX3243EAI+T

Maxim Integrated · Pre-ordered Chips · SSOP-28-208mil

MAX3243EAI+T from Maxim Integrated, in a SSOP-28-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 C2+ passive Positive terminal of the inverting charge-pump capacitor (C2).
2 C2- passive Negative terminal of the inverting charge-pump capacitor (C2).
3 V- power_out -5.5V generated by the charge pump; the transmitters are enabled only when the magnitude of V- exceeds approximately 3V.
4 R1IN input RS-232 receiver input with an input voltage range of -25V to +25V.
5 R2IN input RS-232 receiver input with an input voltage range of -25V to +25V.
6 R3IN input RS-232 receiver input with an input voltage range of -25V to +25V.
7 R4IN input RS-232 receiver input with an input voltage range of -25V to +25V.
8 R5IN input RS-232 receiver input with an input voltage range of -25V to +25V.
9 T1OUT output RS-232 transmitter output with a swing of at least ±5.0V into a 3kΩ load.
10 T2OUT output RS-232 transmitter output with a swing of at least ±5.0V into a 3kΩ load.
11 T3OUT output RS-232 transmitter output with a swing of at least ±5.0V into a 3kΩ load.
12 T3IN input TTL/CMOS transmitter input with a logic threshold low of 0.8V maximum and a threshold high of 2.0V (VCC=3.3V) or 2.4V (VCC=5.0V).
13 T2IN input TTL/CMOS transmitter input with a logic threshold low of 0.8V maximum and a threshold high of 2.0V (VCC=3.3V) or 2.4V (VCC=5.0V).
14 T1IN input TTL/CMOS transmitter input with a logic threshold low of 0.8V maximum and a threshold high of 2.0V (VCC=3.3V) or 2.4V (VCC=5.0V).
15 R5OUT tri_state Inverting TTL/CMOS receiver output, three-state, with output voltage low of 0.4V maximum at 1.6mA.
16 R4OUT tri_state Inverting TTL/CMOS receiver output, three-state, with output voltage low of 0.4V maximum at 1.6mA.
17 R3OUT tri_state Inverting TTL/CMOS receiver output, three-state, with output voltage low of 0.4V maximum at 1.6mA.

19 R1OUT tri_state Inverting TTL/CMOS receiver output, three-state, with output voltage low of 0.4V maximum at 1.6mA.
20 R2OUTB output Noninverting receiver output that remains active in shutdown to monitor receiver activity such as Ring Indicator.
21 INVALID output Output of the valid signal detector that is high when a valid RS-232 level is present on the receiver inputs.
22 FORCEOFF input Drive low to shut down the transmitters and on-board power supply, overriding all automatic circuitry and FORCEON.
23 FORCEON input Drive high to override the automatic circuitry and keep the transmitters on, with FORCEOFF required to be high.
24 C1- passive Negative terminal of the voltage doubler charge-pump capacitor (C1).
25 GND power_in Ground reference for the device.
26 VCC power_in Supply voltage of +3.0V to +5.5V.
27 V+ power_out +5.5V generated by the charge pump.
28 C1+ passive Positive terminal of the voltage doubler charge-pump capacitor (C1).
