ICL3221ECAZ
Transceiver RS232, 250 Kbps, 3V-5.5V supply, SSOP-16
產品總覽
The ICL3221ECAZ is a powered RS-232 Transmitter/Receiver with marking. It meets ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3V. It provides ±15kV ESD protection on transmitter outputs and receiver inputs. Efficient on-chip charge pumps, coupled with manual and automatic power-down functions, reduce the standby supply current to a 1µA trickle. Data rates greater than 250kbps are guaranteed at worst case load conditions. This family is fully compatible with 3.3V only systems, mixed 3.3 and 5V systems and 5V only systems. It features an automatic power-down function which powers down the on-chip power-supply and driver circuits. This occurs when an attached peripheral device is shut OFF or the RS-232 cable is removed, conserving system power automatically without changes to the hardware or operating system. This device power up again when a valid RS-232 voltage is applied to any receiver input.
- ESD Protection for RS-232 I/O pins to ±15kV
- Latch-up free
- On-chip voltage converters require only four external 0.1µF capacitors
- Manual and automatic power-down
- Receiver hysteresis for improved noise immunity
- 250kbps Guaranteed minimum data rate
- 1µA Low supply current in power-down state
