UT912D General Description

The UTC UT912D of CMOS LSIs for remote control system applications are paired with UTC UT912E (refer to the encoder/decoder cross reference table) and is capable of decoding information which consists of N address bits and 12-N data bits. For proper operation, a pair of encoder/decoder with the same number of addresses and data format should be chosen.The UTC UT912D also is arranged to provide 8 address bits and 4 data bits.

The decoders receive serial addresses and data from a programmed UTC UT912E of encoders that are transmitted together with the header bits by a RF or an infrared transmission medium upon receipt of a trigger signal. If no error or unmatched codes are found, the input data codes are decoded and then transferred to the output pins. The VT pin also goes high to indicate a valid transmission.

UT912D Maximum Ratings

PARAMETER	SYMBOL	RATINGS	UNIT
Supply Voltage	V_DD	-0.3 ~ +13	V
Input Voltage	V_IN	Vss-0.3 ~ V_DD+0.3	V

UT912E General Description

The UTC UT912E of CMOS LSIs for remote control system applications is capable of encoding information which consists of N address bits and 12-N data bits. Each address/data input can be set to one of the two logic states. The programmed addresses/data are transmitted together with the header bits by a RF or an infrared transmission medium upon receipt of a trigger signal.

Input Voltage	Vss-0.3 ~ VDD+0.3	VIN	V
Operating Temperature	0 ~ +70	TOPR
Storage Temperature	-40 ~ +150	TSTG

UT912E Features

* Operating voltage: 2.4V ~ 12V
* Low power and high noise immunity CMOS technology
* Low standby current (0.1A (typ.) at VDD=5V)
* Minimum transmission word (Four words)
* Built-in oscillator needs only 5% resistor
