Description
These quad differential drivers are TTL input-to-pseudo-ECL-differential-output used for digital data transmission over balanced transmission lines. All devices in this family have four drivers with a single enable control in a common package. These drivers are compatible with many receivers, including the Agere Systems Inc. 41 Series receivers and transceivers. They are pin equivalent to the general-trade 26LS31, but offer increased speed, decreased power consumption, and significantly lower levels of electro-magnetic interference (EMI). They replace the Agere 41 Series drivers.

FEATUREs
