MAXIM MAX3314EUA+

The MAX3314 is a ±5V powered EIA/TIA - 232 - compatible interface. It has one transmitter and one receiver in a flow - through architecture. The transmitter has a lowdropout output stage providing minimum RS - 232 - compatible ±3.7V output levels while driving 3kΩ and 1000pf at 460kbps. Both +5V and - 5V are supplied externally. The MAX3314 has a SHDN function that reduces supply current to 1µA. The transmitter is disabled and put into 3 - state mode while the receiver remains active. The MAX3314 is available in 8 - pin SOT23, µMAX and SO packages. The transmitter is an inverting level translator that converts CMOS - logic levels to EIA/TIA - 232 - compatible levels. It guarantees data rates up to 460kbps with worst - case loads of 3kΩ in parallel with 1000pF. When SHDN is driven low, the transmitter is disabled and put into 3 - state mode. The transmitter input does not have a pull - up resistor. Connect to ground if unused. The MAX3314’s receiver converts RS - 232 signals to CMOS - logic output levels. The receiver is rated to signals up to ±25V. The MAX3314’s receiver will remain active during shutdown mode. In shutdown mode, the transmitter output is put into high impedance. This reduces the supply current to 1µA. The time required to exit shutdown is less than 2.5µs. The MAX3314 maintains minimum RS - 232 - compatible ±3.7V transmitter output voltage even at high data rates.
