description
The MC3453 and MC3553 feature four line drivers
with a common-enable input. When the ENABLE
input is high, a constant output current is switched
between each pair of output terminals in response
to the logic level at that channel input. When the
ENABLE is low, all channel outputs are
nonconductive (transistors biased to cutoff). This
minimizes loading in party-line systems where a
large number of drivers share the same line.
The driver outputs have a common-mode voltage
range of –3 V to 10 V, allowing common-mode
voltages on the line without affecting driver
performance.
All outputs should be maintained within the
recommended common-mode output voltage
range to ensure that the channels do not interact
with each other. To minimize power dissipation, all
unused outputs should be grounded.
All inputs are diode clamped and are designed to satisfy TTL-system requirements. The inputs are tested at
2 V for high-logic-level input conditions and 0.8 V for low-logic-level input conditions. These tests ensure 400
mV of noise margin when interfaced with Series 54/74 TTL.
The MC3453 is characterized for operation from 0
°
C to 70
°
C. The MC3553 is characterized for operation over
the full military temperature range of –55
°
C to 125
°
C.
