Description

The TPT9L484 is a 3.3V 4-CH Low-Voltage

Differential (LVDS) line receivers, which can support

400 Mbps data rates. Receiver inputs are protected

against ±8kV ESD strikes without latch-up.

The TPT9L484 can accept low voltage differential

input signals as 350 mV typical, and translates them

to 3.3V CMOS output levels. The receivers support a

Tri-state function that may be used to multi-channel

outputs. The receivers also support open, shorted,

and terminated (100 Ω) input Fail-safe, with holding

output as HIGH level. The device is characterized for

operation from –40°C to 85°C. The device is available

in 16-lead TSSOP package.
