Product Summary
The MX614DW is a low voltage, low power CMOS integrated circuit designed for the reception or transmission of asynchronous 1200bps data. This device is compatible with Bell 202 type systems. The MX614 supports 5bps and 150bps ‘back channel’ operation. The MX614DW provides an optional Tx and Rx data retiming function which can eliminate, based on user preference, the need for a UART in the associated μC when operating at 1200bps. An optional line equalizer has been incorporated into the receive path and is controlled by an external logic level. Applications of the MX614DW include: Low Voltage Operation (3.3V to 5.0V); Low Power Operation: 1mA typ. @ 3.3V Operating Mode, 1μA typ. Zero-Power Mode; Standard 3.58MHz Xtal/Clock; Telephone Telemetry Applications.
Parametrics
MX614DW absolute maximum ratings: (1)Supply (VDD - VSS): -0.3 to 7.0 V; (2)Voltage on any pin to VSS: -0.3 to VDD + 0.3 V; (3)VDD: -30 to 30 mA; (4)VSS: -30 to 30 mA; (5)Any other pins: -20 to 20 mA; (6)Total Allowable Power Dissipation at TAMB = 25℃: 800 mW; (7)Derating above 25℃: 13 mW/℃ above 25℃; (8)Storage Temperature: -55 to 125 ℃; (9)Operating Temperature: -40 to 85 ℃.
Features
