DESCRIPTION

These quad differential drivers are TTL input to

pseudo-ECL differential output used for digital data

transmission over balanced transmission lines.

The TB5D1M device is a pin and functional

replacement for the Agere systems BDG1A and

BPNGA quad differential drivers. The TB5D1M has a built-in lightning protection circuit to absorb large

transitions on the transmission lines without

destroying the device. When the circuit is powered

down it loads the transmission line, because of the

protection circuit.

The TB5D2H device is a pin and functional

replacement for the Agere systems BDG1A and BDGLA quad differential drivers. Upon power down

the TB5D2H output circuit appears as an open circuit

and does not load the transmission line.

Both drivers feature a 3-state output with a third-state

level of less than 0.1 V.

The packaging options available for these quad

differential line drivers include a 16-pin SOIC

gull-wing (DW) and a 16-pin SOIC (D) package.

Both drivers are characterized for operation from

-40C to 85C

The logic inputs of this device include internal pull-up

resistors of approximately 40 kΩ that are connected

to VCC to ensure a logical high level input if the inputs

are open circuited.
