Vishay Intertechnology, Inc. has expanded its family of
MIL-PRF-38535-screened analog switches and multiplexers
with the release of the hi-rel DG408, an 8-channel, single-ended
analog multiplexer.
In June 2010, the Vishay Siliconix facility in Santa Clara,
Calif. was re-qualified by DSCC to manufacture analog switches
and multiplexers with screening to MIL-PRF-38535. The MIL-PRF-38535
specification is a standard that establishes the performance,
quality, and reliability requirements for IC components
used in systems being built for military and critical avionic
applications.
The hi-rel DG408 joins the previously released DG409 as
products manufactured under this new certification. Designed
to connect one of eight inputs to a common output determined
by a 3-bit binary address, the new DG408 is optimized for
high-speed data acquisition, audio signal routing, and battery
powered and remote instrumentation.
The device features a 44 V maximum supply rating, low on-resistance
of 100 ?, and low charge injection of 20 pC. The DG408's
enable pin allows multiple devices to be used together to
increase the number of input signals in an application.
Three military package options are available: the 16-pin
CerDIP (DSCC# 5962-9204201MEA), the 20-pin LCC (DSCC# 5962-9204201M2A
and 5962-9204201M2C), and the 16-pin Flat-Pack (DSCC# 5962-9204201MXA
and 5962-9204201MXC).
Vishay's additional hi-rel capabilities include Group A,
Group B, Group C, and Group E testing. In addition, Vishay
Siliconix continues to offer source-controlled drawing capabilities
to allow space and avionic-level screening.
The Vishay facility in Santa Clara also is in the process
of becoming qualified for military MOSFETs. All Vishay Siliconix
hi-rel MOSFETs and IC products are manufactured in the Santa
Clara fab, and conform to the most stringent reliability
requirements in the industry. Vishay has long-term relationships
with virtually all of the distributors serving hi-rel markets.
Samples and production quantities of the hi-rel DG408 multiplexers
in the 16-pin CerDIP (DG408AK) are available now, with lead
times of 20 weeks for larger orders. Sample and production
quantities of devices in the 20-pin LCC (DG408AZ) and 16-pin
Flat-Pack (DG408AL) will be available in Q2 2011.
