Holtek HT12A / HT12E 2(12) Series of Encoders
From £0.60 (Ex. VAT)
Holtek HT12A / HT12E 2(12) Series of Encoders
XProduct SKU: HT12E-18DIPLF-P
Holtek HT12A / HT12E 2(12) Series of Encoders
General Description The 2(12) encoders are a series of CMOS LSIs for remote control system applications. They are capable of encoding information which consists of N address bits and 12N 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 via an RF or an infrared transmission medium upon receipt of a trigger signal. The capability to select a TE trigger on the HT12E or a DATA trigger on the HT12A further enhances the application flexibility of the 212 series of encoders. The HT12A additionally provides a 38kHz carrier for infrared systems. Applications - Burglar alarm system - Smoke and fire alarm system - Garage door controllers - Car door controllers - Car alarm system - Security system - Cordless telephones - Other remote control systemsFeatures
- Operating voltage - 2.4V~5V for the HT12A - 2.4V~12V for the HT12E - Low power and high noise immunity CMOS technology - Low standby current: 0.1 A (typ.) at VDD=5V - HT12A with a 38kHz carrier for infrared transmission medium - Minimum transmission word - Four words for the HT12E - One word for the HT12A - Built-in oscillator needs only 5% resistor - Data code has positive polarity - Minimal external components - Pair with Holtek's 2(12 )series of decoders - 18-pin DIP, 20-pin SOP packageFrom£0.60 (Ex.

Holtek HT12D / HT12F 2(12) Series of Decoders
From £0.60 (Ex. VAT)
Holtek HT12D / HT12F 2(12) Series of Decoders
XProduct SKU: HT12D-18DLF-P
General Description
The 2(12) decoders are a series of CMOS LSIs for remote control system applications. They are paired with Holtek s 212 series of encoders (refer to the encoder/decoder cross reference table). For proper operation, a pair of encoder/decoder with the same number of addresses and data format should be chosen.
The decoders receive serial addresses and data from a programmed 212 series of encoders that are transmitted by a carrier using an RF or an IR transmission medium. They compare the serial input data three times continuously with their local addresses. 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.
The 2(12) series of decoders are capable of decoding informations that consist of N bits of address and 12 N bits of data. Of this series, the HT12D is arranged to provide 8 address bits and 4 data bits, and HT12F is used to decode 12 bits of address information.

Holtek HT1380/HT1381 Serial Timekeeper Chip
XProduct SKU: HT1381-8SOPLF
Holtek HT1380/HT1381 Serial Timekeeper Chip
General Description The HT1380/HT1381 is a serial timekeeper IC which provides seconds, minutes, hours, day, date, month and year information. The number of days in each month and leap years are automatically adjusted. The HT1380/HT1381 is designed for low power consumption and can operate in two modes: one is the 12-hour mode with an AM/PM indicator, the other is the 24-hour mode. The HT1380/HT1381 has several registers to store the corresponding information with 8-bit data format. A 32768Hz crystal is required to provide the correct timing. In order to minimize the pin number, the HT1380/HT1381 use a serial I/O transmission method to interface with a microprocessor. Only three wires are required: (1) REST, (2) SCLK and (3) I/O. Data can be delivered 1 byte at a time or in a burst of up to 8 bytes Applications Microcomputer serial clock Clock and CalendarFeatures
Operating voltage: 2.0V~5.5V Maximum input serial clock: 500kHz at VDD=2V, 2MHz at VDD=5V Operating current: less than 1A at 2V, less than 1.2A at 5V TTL compatible - VIH: 2.0V~VDD+0.3V at VDD=5V - VIL: 0.3V~+0.8V at VDD=5V Two data transmission modes: single-byte, or burst mode Serial I/O transmission All registers store BCD format HT1380: 8-pin DIP package HT1381: 8-pin SOP packageFrom£0.65 (Ex.
