what is the maximum number of pulses that can be send to a TSOP1838(infrared receiver module) continuously before a zero is send so that it will be detected as a valid signal.The datasheet only specify that a minimum of 6 pulses is required.
Thank you.Again,let me ask another question.CAN THE TSOP1838 BE USED FOR SERIAL COMMUNICATION up to 2400 bauds JUST LIKE THE TSOP1740 on the following link http://www.rentron.com/Micro-Bot/IR_Serial.htm

2400 baud that is mentioned in data sheet indicates maximum baud rate. but for example if you use TSOP17xx (Or TSOP18xx) in an NRZ data communication (i.e. by using UART of a micro) you may get some troubles. because if you send a byte with value of 255, there is an start bit which is 0 and 8 bit data which have 1 state, and an stop bit which is 1. so there is 9 bit that continuously have 1 state. with 2400 baud, 9 bit takes 3.75ms which violates mentioned note.
