ST3243E Overview
Key Specifications
Package: TSSOP
Mount Type: Surface Mount
Pins: 28
Operating Voltage: 3.3 V
Description
The ST3243E device consists of 3 drivers, 5 receivers and a dual charge-pump circuit. The device meets the requirements of EIA/TIA and V.28/V.24 communication standards providing high data rate capability and enhanced electrostatic discharge (ESD) protection.
Key Features
- The device is guaranteed to run at data rates of 250kbps while maintaining RS-232 output levels
- The Auto-powerdown feature functions when FORCEON is low and FORCEOFF is high
- During this mode of operation, if the device does not sense a valid RS-232 signal, the driver outputs are SSOP TSSOP disabled
- If FORCEOFF is set low, both drivers and receivers (expert R2B) are shut off, and supply current is reduced to 1µA
- Disconnecting the serial port or turning off the peripheral drives causes the auto-powerdown condition to occur
