TB5R3
www.ti.com SLLS643A – SEPTEMBER 2005 – REVISED OCTOBER 2007 QUAD DIFFERENTIAL PECL RECEIVERS
FEATURES 1 Functional Replacement for the Agere BRF1A
Pin Equivalent to General Trade 26LS32
High Input Impedance Approximately 8 kΩ 3 kV and CDM > 2 kV
Operating Temperature Range: -40В°C to 85В°C
Available in Gull-Wing SOIC (JEDEC MS-013,
DW) and SOIC (D) Package APPLICATIONS Digital Data or Clock Transmission Over
Balanced Lines DESCRIPTION
These quad differential receivers accept digital data
over balanced transmission lines. They translate
differential input logic levels to TTL output logic
levels.
The TB5R3 is a pin-and function-compatible
replacement for the Agere systems BRF1A; it
includes 3-kV HBM and 2-kV CDM ESD protection.
The power-down loading characteristics of the
receiver input circuit are approximately 8 kΩ relative
to the power supplies; hence they do not load the
transmission line when the circuit is powered down.
The packaging for this differential line receiver is a
16-pin gull wing SOIC (DW) or a 16 pin SOIC (D).
The enable inputs of this device include internal …
