The MAX5054–MAX5057 dual, high-speed MOSFET
drivers source and sink up to 4A peak current. These
devices feature a fast 20ns propagation delay and 20ns
rise and fall times while driving a 5000pF capacitive
load. Propagation delay time is minimized and matched
between the inverting and noninverting inputs and
between channels. High sourcing/sinking peak cur-
rents, low propagation delay, and thermally enhanced
packages make the MAX5054–MAX5057 ideal for high-
frequency and high-power circuits.
The MAX5054–MAX5057 operate from a 4V to 15V single
power supply and consume 40µA (typ) of supply current
when not switching. These devices have internal logic
circuitry that prevents shoot-through during output state
changes to minimize the operating current at high
switching frequency. The logic inputs are protected
against voltage spikes up to +18V, regardless of the V
voltage. The MAX5054A is the only version that has
CMOS input logic levels while the MAX5054B/MAX5055/
MAX5056/MAX5057 have TTL input logic levels.
The MAX5055–MAX5057 provide the combination of dual
inverting, dual noninverting, and inverting/noninverting
input drivers. The MAX5054 feature both inverting and
noninverting inputs per driver for greater flexibility. They
are available in 8-pin TDFN (3mm x 3mm), standard SO,
and thermally enhanced SO packages. These devices
operate over the automotive temperature range of -40°C
to +125°C.
