The MAX5054–MAX5057 have internal undervoltage
lockout for V
old, OUT_ is low, independent of the state of the inputs.
The undervoltage lockout is typically 3.5V with 200mV
typical hysteresis to avoid chattering. When V
above the UVLO threshold, the outputs go high or low
depending upon the logic-input levels. Bypass V
using low-ESR ceramic capacitors for proper operation
(see the Applications Information section).

The MAX5054B–MAX5057 have TTL-compatible logic
inputs, while the MAX5054A is a CMOS logic-input dri-
ver. The logic-input signals can be independent of the
V
by a 5V supply while the logic inputs are provided from
CMOS logic. Also, the logic inputs are protected against
the voltage spikes up to 18V, regardless of the V
age. The TTL and CMOS logic inputs have 300mV and
0.1 x V
ble pulsing during transition. The low 2.5pF input capaci-
tance reduces loading and increases switching speed.
