DS26LV32AT

3V Enhanced CMOS Quad Differential Line Receiver

General Description

The DS26LV32A is a high speed quad differential CMOS re-

ceiver that meets the requirements of both TIA/EIA-422-B

and ITU-T V.11. The CMOS DS26LV32AT features typical

low static I

enables, EN and EN*, allow the device to be active 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

ceiver outputs (RO) are compatible with TTL and LVCMOS

levels.
