The SP232AEN-L is an advanced, high-speed, single-channel RS232 line driver/receiver device with a slew rate of up to 25 MBps. It is typically used for applications requiring a high data rate such as high speed modems, serial printers, GPS receivers and other device interfaces.

SP232AEN-L Overview

The SP232AEN-L has a typical power consumption of 8 mA and voltage supply range of 4.0V to 5.5V, making it an ideal solution for low-power applications. The device also features low output slew rate which reduces electromagnetic interference (EMI). It has 3-state drivers which can be activated by driver enable pins, and provides a slow slew rate option to reduce EMI. It is built with CMOS logic levels and a wide temperature range.

The SP232AEN-L comes with a single-channel line driver/receiver with full-duplex asynchronous data communications. It is fully ESD protected and integrates a 2:1 data channel mux with a data input buffer, receiver, transmitter and automatic flow control generator. The receiver has a hysteresis of 400 mV which makes it tolerant to busy line conditions and other interruptions. Additionally, it is designed with Receiver Error Detection and Auto-retransmit mechanism.

SP232AEN-L Working Principle

The SP232AEN-L acts as an interface between two systems, one providing data transmission and the other providing data reception. It consists of a data buffer, a transmit/receive control and an enable/disable control. The data buffer contains the data to be transmitted. The enable/disable control is used to enable and disable the transmission/reception of data. The transmit/receive control is responsible for providing the exact transmission of data without any errors.

The SP232AEN-L also features low output slew rate which reduces EMI and ensures correct timing as well as stable communication. Additionally, it has a hysteresis of 400 mV which makes it tolerant to busy line conditions and other interruptions, and a receiver error detection mechanism for error-free data transmission. Furthermore, its 3-state drivers can be activated by driver enable pins to enable the mapping of long strings.
