±15kV ESD Protected, +3.3V, 1Microamp,
250kbps, RS-232 Transmitters/Receivers
The Intersil 5962-062070xQxA devices are 3.3V powered
RS-232 transmitters/receivers which meet ElA/TIA-232 and
V.28/V.24 specifications, even at V
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 5962-0620703Q2A),
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 3.3V-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.
