3.3V / 460 Kbps RS-232 Transceivers - Sipex
Description
®
SP3222H/3232H 3.
3V, 460 Kbps RS-232 Transceivers
■ Meets true EIA/TIA-232-F Standards from a +3.
0V to +5.
5V power supply ■ Interoperable with RS-232 down to +2.
7V power source ■ 1µA Low-Power Shutdown with Receivers Active (SP3222H) ■ Enhanced ESD Specifications: +2kV Human Body Model ■ 460Kbps Minimum Transmission Rate ■ Ideal for Handheld, Battery Operated Applications
DESCRIPTION The SP3222H and the 3232H are 2 driver/2 receiver RS-232 transceiver solutions intended for portable or hand-held applications such as notebook or palmtop computers.
Their data transmission rate of 460Kbps meeting the demands of high speed RS-232 applications.
Both ICS have a high-efficiency, charge-pump power supply that requires only 0.
1µF capacitors for 3.
3V operation.
The charge pump allows the SP3222H and the 3232H series to deliver true RS-232 performance from a single power supply ranging from +3.
3V to +5.
0V.
The SP3222H device has a low-power shutdown mode where the devices' driver outputs and charge pumps are disabled.
During shutdown, the supply current is less than 1µA.
