DS3650
Quad Differential Line Receivers
General Description
The DS3650 is TTL compatible quad high speed circuits in-
tended primarily for line receiver applications. Switching
speeds have been enhanced over conventional line receiv-
ers by the use of Schottky technology, and TRI-STATE
廬
strobing is incorporated offering a high impedance output
state for bussed organizations.
The DS3650 has active pull-up outputs and offers a
TRI-STATE strobe.
