What is the difference between MAX232 and MAX3232?
MAX232 is 5V voltage, the power consumption is higher than MAX3232, general civilian products use this. MAX3232 is 3.3V, low power consumption and high performance, mainly used in aerospace and places where power consumption is very demanding. There is no difference in performance between the two.
How does MAX3232 work?
MAX3232 is a commonly used rs232 to ttl converter ic. It consists of two line drivers, two line receivers, and a dual charge-pump circuit with terminal to terminal ESD protection of 15 kV. The charge pump and four small external capacitors allow the device to operate from a single 3V to 5.5V supply.
What is MAX232 converter?
The MAX232 is a dual transmitter / dual receiver that typically is used to convert the RX, TX, CTS, RTS signals. The drivers provide TIA-232 voltage level outputs (about ±7.5 volts) from a single 5-volt supply by on-chip charge pumps and external capacitors.
Why do we need MAX232?
MAX232 IC is widely used for serial communication among Microcontrollers & PC. The main function of this integrated circuit is to change the logic levels of TTL/CMOS to RS232 throughout the serial communication process.
What is the need for MAX232?
What is the MAX3232 device?
The MAX3232 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection terminal to terminal (serial-port connection terminals, including GND).
What are the specifications of the max3222/max3232/max3237/max 3241 transceivers?
General Description. The MAX3222/MAX3232/MAX3237/MAX3241 transceivers have a proprietary low-dropout transmitter output stage enabling true RS-232 performance from a 3.0V to 5.5V supply with a dual charge pump. The devices require only four small 0.1µF external charge-pump capacitors.
What is the VCC of the max3222/max3232/max3237/max3241?
5V/div VCC= 3.3V C1–C4 = 0.1µF 2V/div T2 50µs/div T1 MAX3222/MAX3232/ MAX3237/MAX3241 3.0V to 5.5V, Low-Power, Up to 1Mbps, True RS-232 Transceivers
What is the difference between MAX232 and MAX3232 ICS?
Both ICs have the same pin-out and package style, so they are a direct substitute. The main improvement in MAX3232 is that it can support both 3.3V and 5V systems, whereas the predecessor MAX232 could only support 5V systems.
