Features 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 package 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

Product Details:

Minimum Order Quantity100 Piece
BrandHOLTEK
Part No.HT9170D
Model NumberHT9170D
ApplicationDTMF

The HT9170D-18SOPLF is a DTMF (Dual Tone Multi Frequency) receiver in 18 pin SOP package. This receiver has integrated digital decoder, bandsplit filter function as well as power down mode and inhibit mode operations. It uses digital counting techniques to detect and decode all 16 DTMF tone pairs into 4bit code output. Highly accurate switched capacitor filters are implemented to divide tone signals into low and high group signals. A built-in dial tone rejection circuit is provided to eliminate need for prefiltering.
  • Operating voltage range from 2.5V to 5.5V
  • 3.58MHz crystal or ceramic resonator
  • Minimal external components
  • No external filter is required
  • Low standby current on power down mode
  • Excellent performance
  • Tristate data output for MCU interface
  • 1633Hz can be inhibited by INH pin
  • Operating temperature range from -20°C to 75°C
