LTC1045CSW#PBF

Translators, Level Shifters Overview

The LTC1045CSW#PBF is a hex level translator manufactured using enhanced LTCMOS silicon gate process. It integrates six high-speed comparators with output latches and three-state capability. The device features programmable power and speed via an external resistor on the ISET pin, allowing bias current adjustment. Each comparator includes internal hysteresis for noise immunity. The part operates within a supply voltage range of 3V to 15V and supports an operating temperature range from -40°C to 85°C.

Translators, Level Shifters Feature Summary
