This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
DESCRIPTION (CONT.)
The UCC2752x family provide the combination of three standard logic options - dual-inverting, dual-non inverting,
one inverting and one non-inverting driver. UCC27526 features a dual input design which offers flexibility of both
inverting (IN- pin) and non-inverting (IN+ pin) configuration for each channel. Either IN+ or IN- pin can be used to
control the state of the driver output. The unused input pin can be used for enable and disable functions. For
safety purpose, internal pull-up and Pull-down resistors on the input pins of all the devices in UCC2752x family in
order to ensure that outputs are held LOW when input pins are in floating condition. UCC27323, UCC27324 and
UCC27325 feature an Enable pins (ENA and ENB) to have better control of the operation of the driver
applications. The pins are internally pulled up to VDD for active high logic and can be left open for standard
operation.
UCC2752x family of devices are available in SOIC-8 (D), MSOP-8 with exposed pad (DGN) and 3-mm x 3-mm
WSON-8 with exposed pad (DSD) packages. UCC27524 is also offered in PDIP-8 (P) package. UCC27526 is
only offered in 3-mm x 3-mm WSON (DSD) package.
