FEATURES:

• A-Port outputs have equivalent 22-Ω series resistors, so

no external resistors are required

• Support mixed-mode signal operation (5V input and output
voltages with 3.3V V

• Support unregulated battery operation down to 2.7V

•Typical V

DESCRIPTION:

Maxwell Technologies’ 54LVTH162245 devices are 16-bit
(dual-octal) non-inverting 3-state transceivers designed for
low-voltage (3.3V) V
provide a TTL interface to a 5V system environment. These
devices can be used as two 8-bit transceivers or one 16-bit
transceiver. The devices allow data transmission from the A
bus to the B bus or form the B bus to the A bus, depending on
the logic level at the direction-control (DIR) input. The output
enable (OE
the buses are effectively isolated. The A-port outputs, which
are designed to source or sink up to 12 mA, include equivalent
22-

Ω series resistors to reduce overshoot and undershoot.

Maxwell Technologies' patented R
ogy incorporates radiation shielding in the microcircuit pack­age. It eliminates the need for box shielding while providing
the required radiation shielding for a lifetime in orbit or space
mission. In a GEO orbit, R

1. Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are
stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “rec­ommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may
affect device reliability.

2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
