Through the use of the control pins (1G and 2G), the outputs can be placed in a low state regardless of the A input. The propagation delays are adjusted at the factory using the P0 and P1 pins. These pins are not intended for customer use and should be strapped to GND. The CDC341 is characterized for operation from 0°C to 70°C.

Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. The maximum package power dissipation is calculated using a junction temperature of 150°C and a board trace length of 750 mils.
