General Description:
The TC1426/TC1427/TC1428 are a family of 1.2A dual
high-speed drivers. CMOS fabrication is used for low-
power consumption and high efficiency.
These devices are fabricated using an epitaxial layer to
effectively short out the intrinsic parasitic transistor
responsible for CMOS latch-up. They incorporate a
number of other design and process refinements to
increase their long-term reliability.
The TC1426 is compatible with the bipolar DS0026, but
only draws 1/5 of the quiescent current. The TC1426/
TC1427/TC1428 are also compatible with the TC426/
TC427/TC428, but with 1.2A peak output current rather
than the 1.5A of the TC426/TC427/TC428 devices.
Other compatible drivers are the TC4426/TC4427/
TC4428 and the TC4426A/TC4427A/TC4428A. The
TC4426/TC4427/TC4428 have the added feature that
the inputs can withstand negative voltage up to 5V with
diode protection circuits. The TC4426A/TC4427A/
TC4428A have matched input to output leading edge
and falling edge delays, t
D1
and t
D2
, for processing
short duration pulses in the 25 nanoseconds range. All
of the above drivers are pin compatible.
The high-input impedance TC1426/TC1427/TC1428
drivers are CMOS/TTL input-compatible, do not require
the speed-up needed by the bipolar devices, and can
be directly driven by most PWM ICs.
This family of devices is available in inverting and non-
inverting versions. Specifications have been optimized
to achieve low-cost and high-performance devices,
well-suited for the high-volume manufacturer.
