## Description

The Vishay TOIM4232 is an Endec IC that provides essential pulse shaping for SIR IrDA front-end infrared transceivers. It is designed to shorten RS232 output signals into IrDA-compatible electrical pulses for driving infrared transmitters. In receive mode, it stretches received infrared pulses to the correct bit width based on the operating bit rate, which can range from 2.4 kbit/s to 115.2 kbit/s.

This integrated interface circuit operates within a voltage range of 2.7 V to 3.6 V and features 5 V tolerant inputs. It utilizes a 3.6864 MHz crystal clock for its pulse stretching and shortening functions, with the option for an external clock. The TOIM4232 is programmable via the RS232 port for baud rates from 1200 bit/s to 115.2 kbit/s. Users can select output pulses to be either 1.627 µs or 3/16 of the bit time. The device is housed in a 16-pin SOP package and offers low operating current, consuming approximately 10 mW in operational state and only a few microwatts in standby mode.

Key features include direct interfacing with SIR transceivers to an RS232 port, a programmable baud clock generator, and selectable pulse durations. The TOIM4232 is suitable for applications requiring infrared communication via the IrDA standard.
