IC TRANSCEIVER FULL 5/3 28SSOP
The MAX3237EAI transceiver offers a patented low-dropout transmitter output stage that enables genuine RS-232 performance from a 3.0V to 5.5V supply. This article mainly introduces Circuits, Pinout, Datasheet and other detailed information about Maxim Integrated MAX3237EAI.
With a twin charge pump, the MAX3237EAI transceiver offers a patented low-dropout transmitter output stage that enables genuine RS-232 performance from a 3.0V to 5.5V supply. Only four modest 0.1F external charge-pump capacitors are required for the devices. The MAX3237EAI ensures that data speeds of 120kbps are maintained while preserving RS-232 output levels. In normal working mode, the MAX3237EAI is guaranteed to run at 250kbps, and in MegaBaudTM mode, it is guaranteed to run at 1Mbps.
Three receivers and five drivers are included in the MAX3237EAI. In addition to the usual outputs, receiver R1 (MAX3237EAI) features additional outputs. These additional outputs are constantly active, allowing external devices to be monitored without forward biasing protection diodes in circuits with no VCC.
