Features Conforms to TIA/EIA-232-E and CCITT V.28 specifications Operates with single +3.3V power supply Low power requirement-ICC 20 mA maximum SHUTDOWN mode-ICX 10 µA maximum One Receiver (R5) active during SHUTDOWN Operates up to 128 kbps-Lap-Link® Compatible Flow through pinout 4V/µs minimum Slew Rate guaranteed Inter-operates with +5V UARTs Available in 28-lead SSOP EIAJ Type II package Description The DS14C335 is three driver, five receiver device which conforms to TIA/EIA-232-E and CCITT V.28 standard specifications. This device employs an internal DC-DC converter to generate the necessary output levels from a +3.3V power supply. A SHUTDOWN (SD) mode reduces the supply current to 10 µA maximum. In the SD mode, one receiver is active, allowing ring indicator (RI) to be monitored. PC Board space consumption is minimized by the availability of Shrink Small Outline Packaging (SSOP). This device's low power requirement and small footprint makes it an ideal choice for Laptop and Notebook applications.

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
DS14C335MSA	P2CMOS	0	50860	0	1	4503500	2	578995367
DS14C335MSAX	P2CMOS	0	50860	0	1	4503500	2	578995367

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
