DS26LV32AT
3V Enhanced CMOS Quad Differential Line Receiver
General Description
The DS26LV32A is a high speed quad differential CMOS
receiver that meets the requirements of both TIA/EIA-422-B
and ITU-T V.11. The CMOS DS26LV32AT features typical
low static I
powered and power conscious applications. The TRI-
STATE
High or active Low. The enables are common to all four
receivers.
The receiver output (RO) is guaranteed to be High when the
inputs are left open. The receiver can detect signals as low
as
receiver outputs (RO) are compatible with TTL and LVCMOS
levels.
