LC7367规格书详情
Overview
The LC7367J, 7367JM are DTMF/OUTPUT-PULSE dialer CMOS ICs with redial function for use in pushbutton telephones.
Features
• Low voltage CMOS process for direct operation from telephone line.
• Possible to use single contact or standard 2-of-7, 2-of-8 key pad.
• Possible to use color-burst crystal resonator for on-chip oscillator (fOSC=3.58MHz).
• Possible to use either mode select pin (P/T) or function key (4×4 matrix key) to select DTMF mode/OUTPUTPULSE mode.
• Mode change with MC key is made in one direction onlyfrom pulse mode to tone mode.
• Delivers 12 DTMF signals when in DTMF mode.
• On-chip 31-digit redial memory.
• Possible to provide mix redial (31 digits-PAUSE-MC) of DTMF/OUTPUT-PULSE mode.
• Either auto pause select (4s.×n) or manual release available for mode select standby time during redial operation.
• Output pulse make rate of OUTPUT-PULSE mode : Pinselectable (33.2 or 40).
• Output pulse rate of OUTPUT-PULSE mode : Pinselelctable (10pps or 20pps).
• On-chip circuit to prevent malfunction due to noise pulse caused by key entry.
• Key touch tone (pacifier tone) output capability. OUTPUT-PULSE mode : 1243Hz/50ms
• Supply voltage / operating temperature
DTMF mode :
VDD=2.0 to 6.0V / Ta=–30 to +70°C
OUTPUT-PULSE mode :
VDD=1.5 to 6.0V / Ta=–30 to +70°C
• Operating current
DTMF mode :
IDD=1.0mA max / VDD=3.5V
OUTPUT-PULSE mode :
IDD=500µA max / VDD=3.5V
• Data retention current IDR≤0.5µA / VDD=1.0V
• Package
LC7367J : Dual-in-line shrink 22-pin package
LC7367JM : Miniflat 30-pin package
