ISL4260E

QFN Packaged, ±15kV ESD Protected, +3V to +5.5V, 150nA, 250kbps,

RS-232 Transmitters/Receivers with Separate Logic Supply

The ISL4260E contains 3.0V to 5.5V powered RS-232

transmitters/receivers that meet ElA/TIA-232 and

Features

• Available in near chip scale QFN (5mmx5mm)

package

V.28/V.24 specifications, even at V = 3.0V.

Targeted applications are PDAs, Palmtops, and cell

phones where the low operational power consumption

and even lower standby power consumption is critical.

Efficient on-chip charge pumps coupled with a manual

powerdown function reduces the standby supply

current to a 150nA trickle. The 5mm x 5mm Quad Flat

No-Lead (QFN) packaging and the use of small, low

value capacitors ensure board space savings. Data

rates greater than 250kbps are ensured at worst case

load conditions.

• V pin for compatibility with mixed voltage systems

• ESD protection for RS-232 I/O pins to ±15kV

(IEC61000)

• Single SHDN pin disables transmitters and

receivers

• Meets EIA/TIA-232 and V.28/V.24 specifications

at 3V

• On-chip charge pumps require only four external

0.1µF capacitors

The ISL4260E features a V pin that adjusts the logic

pin output levels (see Pin Descriptions) and input

• Receiver hysteresis for improved noise immunity

• Very low supply current: 300µA

thresholds to values compatible with the V

powering the external logic (for example, a UART).

• Guaranteed minimum data rate: 250kbps

• Wide power supply range: Single +3V to +5.5V

• Low supply current in powerdown state: 150nA

• Pb-free (RoHS compliant)

The single pin powerdown function (SHDN = 0)

disables all the receiver and transmitter outputs while

shutting down the charge pump to minimize supply

current drain.

Table 1 summarizes the features of the ISL4260E.

Application Note AN9863 summarizes the features of

each device comprising the 3V RS-232 family.

Applications

• Any system requiring RS-232 communication ports
