New, Flexible Low-Power, Low-Leakage Quad RS-422 Transmitters from Intersil Deliver Maximum ESD Protection in Industry’s Smallest Packages
ISL32179E, ISL32272E/74E Feature Extended Voltage and Temperature Ranges for Motor and Process Control, Telecommunications, Factory Automation Applications
MILPITAS, CA, June 1, 2009 – Intersil Corporation (NASDAQ Global
Select: ISIL), a world leader in the design and manufacture of high-performance
analog and mixed-signal semiconductors, has developed a new series of
small-footprint quad 16.5kV ESD-protected RS-422 transmitters. These innovative
new devices feature wide supply-voltage operating ranges for motor control
applications, process control networks, telecommunications products and factory
automation systems.
The new
ISL32179E,
ISL32272E and
ISL32274E withstand ESD during assembly and while in use, featuring +/- 16.5
kV ESD protection that meets HBM and IEC61000-4-2 standards on transmitter
outputs. All of the new transmitters also feature power-saving low-output
leakage currents, at just ± 20μA. Designed to operate from either 3.3V or 5V and
at temperatures between -40 to 125 degrees C, the new transmitters can replace
existing RS-422 transmitters that are restricted to 5V supply voltages or that
operate in limited temperature ranges.
The
ISL32179E,
ISL32272E and
ISL32274E are superior choices for designs using the RS-422 communication
interface, providing maximum protection from the harshest ESD events during
assembly and use. Data rates reach 32 Megabits/second, and quiescent current is
a low 0.8 mA, maximum. Slew rate-limited versions are also offered, so low data
rate applications can minimize EMI and transmission line reflections. Shutdown
supply current is as low as 60 μA on the QFN package versions. Driver (Tx)
outputs are tri-statable, and incorporate a hot-plug feature to keep them
disabled during power-up and power-down.
Industry-standard versions are available in TSSOP or widely used NSOIC
packages, while the
ISL32179E is offered in tiny 4mm x 4mm QFN packages that are 50 percent
smaller than the TSSOPs, providing significant board-space savings. The
ISL32179E also features data-rate and enable options, offering maximum
design versatility. Multiple enable pins allow the user to choose active high or
low group enables (EN or EN#), paired-enables (EN12 and EN34) or individual
channel enables, available on the
ISL32179E, and speed select pins allow the user to select data rates from
460kbps to 32Mbps, also available only on the
ISL32179E. The ultra-small QFN package incorporates a VL pin to adjust the
logic-pin input thresholds, eliminating the need for extended voltage level
translator ICs in most designs.
Pricing and Availability
The
ISL32272E and
ISL32274E are available now in 16-lead TSSOP and 16-lead SOIC packages, with
prices starting at $1.60 each in 1,000-piece units. The
ISL32179E comes in a 24-lead QFN, with prices starting at $1.73 each in
1,000-piece quantities.
