The internal circuit is composed of 3 stages including buffer output, which provide high noise immunity and stable output. SOT23-5L SOT323-5L ORDER CODES PACKAGE T&R SOT23-5L SOT323-5L 74LX1G132STR 74LX1G132CTR Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fall input signals. All inputs and outputs are equipped with protection circuits against static discharge.
