Data Sheet May 31, 2006
±15kV ESD Protected, +5.0V 1Microamp,
250kbps, RS-232 Transmitters/Receivers
The Intersil 5962-062070xQxA devices are 5.0V powered
RS-232 transmitters/receivers which meet ElA/TIA-232 and
V.28/V.24 specifications. Additionally, they provide ±15kV
ESD protection (IEC61000-4-2 Air Gap and MIL-STD 883
Human Body Model) on transmitter outputs and receiver
inputs (RS-232 pins). Targeted applications include
ruggedized portable products and remotely deployed
devices exposed to extreme temperature and humidity
where the low operational and even lower standby, power
consumption is critical. Efficient on-chip charge pumps,
coupled with manual and automatic power-down functions
(except for the 5962-0620707Q2A), reduce the standby
supply current to a 1µA trickle. Small footprint packaging and
the use of small, low value capacitors ensure board space
savings as well. Data rates greater than 250kbps are
guaranteed at worst case load conditions. This family is fully
compatible with 5.0V-only systems.
Specifications for QML devices are controlled by the
Defense Supply Center in Columbus (DSCC). The SMD
numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-06207. A “hot-link” is provided
on our website for downloading.
