PRODUCTION DATA.
UCC27517A-Q1 features a dual-input design which offers flexibility of implementing both inverting (IN– pin) and non-inverting (IN+ pin) configurations with the same device. Either the IN+ or IN– pin are used to control the state of the driver output. The unused input pin is used for the enable and disable functional. For protection purpose, internal pullup and pulldown resistors on the input pins ensure that outputs are held low when input pins are in floating condition. Hence the unused input pin is not left floating and must be properly biased to ensure that driver output is in enabled for normal operation.
The input-pin threshold of the UCC27517A-Q1 device is based on TTL and CMOS compatible low-voltage logic which is fixed and independent of the VDD supply voltage. Wide hysteresis between the high and low thresholds offers excellent noise immunity.
