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.
