SY100S325JY

Translators, Level Shifters Overview

The SY100S325JY is a low-power hex ECL-to-TTL translator manufactured by Microchip Technology. It converts 100K ECL logic levels to TTL logic levels and features differential inputs with built-in offset, voltage and temperature compensation for improved noise immunity, and an internal reference voltage generator providing VBB for single-ended use. The device includes internal 75kΩ input pull-down resistors and outputs that go LOW when inputs are open or have the same potential. It operates within an extended supply voltage range of VEE = –4.2V to –5.5V and VTTL = +4.5V to +5.5V. The maximum propagation delay is 3.7ns at 50pF load, and it is available in a 28-pin PLCC package.
