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.
