ISL4223EIRZ-TK is a RS-232 transmitter/receiver that meets ElA/TIA-232 and V.28/V.24 specifications, even at VCC=3.0V. It provides ±15kV ESD protection (IEC61000-4-2 air gap and human body model) on transmitter outputs and receiver inputs (RS-232 pins). It features an automatic power down function that powers down the on-chip power supply and driver circuits. Automatic power down occurs when an attached peripheral device is shut off or the RS-232 cable is removed, and conserves system power automatically without changing to the hardware or operating system. Targeted applications are any space-constrained system requiring RS-232 ports : battery powered and portable equipment, hand-held products (GPS receivers, bar code scanners, etc.), PDAs and palmtops, data cables, cellular/mobile phones, digital cameras.
- RS-232 compatible with VCC=2.7V
- On-chip voltage converters require only four external 0.1µF capacitors
- Receiver hysteresis for improved noise immunity
- Assured minimum data rate: 250kbps
- Wide power supply range: single +2.7V to +5.5V
- 2 number of Tx, 2 number of Rx
- Rx enable function, manual power down, automatic power down function
- Transition region slew rate is 30V/µs max at CL=150pF to 2500pF
- 20 Ld QFN package
- Temperature range from -40 to +85°C
