The voltage levels on outputs SRG1OUT, SRG2OUT, SRG3OUT, and TRGOUT are controlled by the levels on the two dc supply inputs V_SS and V_CC. The propagation delays for these outputs are controlled by the SEL0 and SEL1 inputs. The inputs PD\, SRG1IN, SRG2IN, SRG3IN, and TRGIN are TTL compatible.

A high level on the PD\ input allows the SN28846 to operate normally with the level-shifted outputs following the inputs. When PD\ is low, the device is in a low-power-consumption mode and all outputs are at V_CC.

The SN28846 is available in the DW surface-mount package and is characterized for operation from -20°C to 45°C.

This device contains circuits to protect its inputs and outputs against damage due to high static voltages or electrostatic fields. These circuits have been qualified to protect this device against electrostatic discharges (ESD) of up to 2 kV according to MIL-STD-883C, Method 3015; however, precautions should be taken to avoid application of any voltage higher than maximum-rated voltages to these high-impedance circuits. During storage or handling, the device leads should be shorted together or the device should be placed in conductive foam. In a circuit, unused inputs should always be connected to an appropriated logic voltage level, preferably either V_CC or ground. Specific guidelines for handling devices of this type are contained in the publication Guidelines for Handling Electrostatic-Discharge-Sensitive (ESDS) Devices and Assemblies available from Texas Instruments.
