QUAD DIFFERENTIAL PECL DRIVERS

The TB5D1M device is a pin and functional

replacement for the Agere systems BDG1A and

• Functional Replacements for the Agere

BPNGA quad differential drivers. The TB5D1M has a

BDG1A, BPNGA and BDGLA

built-in lightning protection circuit to absorb large

• Pin-Equivalent to the General-Trade 26LS31

transitions on the transmission lines without

destroying the device. When the circuit is powered

down it loads the transmission line, because of the

• 2.0 ns Maximum Propagation Delays

protection circuit.

• 0.15 ns Output Skew Typical Between Pairs

The TB5D2H device is a pin and functional

• Capable of Driving 50- Ω Loads

and does not load the transmission line.

• TB5D2H No Line Loading When V

= 0

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

level of less than 0.1 V.

• Third State Output Capability

• -40C to 85C Operating Temp Range

The packaging options available for these quad

differential line drivers include a 16-pin SOIC

• ESD Protection HBM > 3 kV and CDM > 2 kV

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

• Available in Gull-Wing SOIC (JEDEC MS-013,

DW) and SOIC (D) Packages

Both drivers are characterized for operation from

-40C to 85C

The logic inputs of this device include internal pull-up

• Digital Data or Clock Transmission Over

resistors of approximately 40 k Ω that are connected

Balanced Transmission Lines

to V

to ensure a logical high level input if the inputs

are open circuited.

These quad differential drivers are TTL input to

pseudo-ECL differential output used for digital data

transmission over balanced transmission lines.

TB5D1M, TB5D2H www.ti.com SLLS579C – SEPTEMBER 2003 – REVISED JANUARY 2008 THIRD STATE—A TB5D1M (or TB5D2H) driver produces pseudo-ECL levels, and has a third-state mode, which is different than a conventional TTL device. When a TB5D1M (or TB5D2H) driver is placed in the third state, the base of the output transistors is pulled low, bringing the outputs below the active-low level of standard PECL devices. [For example: The TB5D1M low output level is typically 2.

This rating correlates with the device's maximum junction temperature, sometimes listed in the absolute maximum ratings tables.
