The SN75LBC968 is a nine-channel transceiver
with active termination that drives and receives
NC − No internal connection
the signals from the single-ended, parallel data
buses such as the Small Computer-Systems
Interface (SCSI) bus. The features of the line drivers, receivers, and active-termination circuits provide the
optimum signal-to-noise ratios for reliable data transmission. Integration of the termination and transceivers in
the LinBiCMOS process provides the necessary analog-circuit performance, has low quiescent power, and
reduces the capacitance presented to the bus over separate termination and I/O circuits.
28
The transceivers of the SN75LBC968 can be enabled to function as totem-pole or open-drain outputs. The
open-drain mode drives the wired-OR lines of SCSI (BSY, SEL, and RST) by inputting the data to the direction
control input DE/RE instead of the A input. When driving the data through the A input, the outputs become totem
poles and provide active signal negation for a higher voltage level on low-to-high signal transitions on heavily
loaded buses. In either mode, the turnon and turnoff output transition times are limited to minimize crosstalk
through capacitive coupling to adjacent lines and RF emissions from the cable. The receivers are also designed
for optimum analog performance by precisely controlling the input-voltage thresholds, providing wide
input-voltage hysteresis and including an input-noise filter. These features significantly increase the likelihood
of detecting only the desired data signal and rejecting noise.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

description (continued)
The communication between the SN75LBC968 and the controller can be accomplished at 3.3-V logic levels
provided that the VCC1 input connects to the same supply rail as the controller. This provides a bridge from the
lower-voltage circuit and the 5-V SCSI bus. The SN75LBC968 also removes the need for special I/O buffers
(and associated power dissipation) on the controller itself. The SN75LBC968 must be used with a SCSI
controller with support for Differential SCSI.
The integrated, current-mode, active termination supplies a constant 24 mA of current (TERMPWR) to the bus
when the bus voltage falls below 2.5 V. This makes the next low-to-high (negation) signal transition independent
of the low-level (asserted) bus voltage, unlike voltage-mode terminators. The termination current is provided
through the TE input and from TERMPWR and can be disabled by letting the TE input float or by connecting
it to ground. The termination circuitry is independent from the line drivers and receivers and VCC or VCC1.
Operational termination is present as long as TERMPWR is applied.
The switching speeds of the SN75LBC968 are sufficient to transfer data over the data bus at ten million transfers
per second (Fast-SCSI). The specification, tsk(lim), is for system skew budgeting and maintenance of bus set-up
and hold times. The device is available in the space-efficient shrink-small-outline package (SSOP) with 25-mil
lead pitch. The SN75LBC968 meets or exceeds the requirements of ANSI X3.131−1994 (SCSI-2) and the
proposed SPI (SCSI-3) standards, and is characterized for operation from 0°C to 70°C.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
