description

TheSN74FB2033Kisan8-bittransceiverfeaturingasplitinput(AI)andoutput(AO)busontheTTL-levelA port.

The common I/O, open-collector B port operates at backplane transceiver logic (BTL) signal levels. The

SN74FB2033K is specifically designed to be compatible with IEEE Std 1194.1-1991.

The logic element for data flow in each direction is configured by two mode inputs (IMODE1 and IMODE0 for

B-to-A, OMODE1 and OMODE0 for A-to-B) as a buffer, a D-type flip-flop, or a D-type latch. When configured

in the buffer mode, the inverted input data appears at the output port. In the flip-flop mode, data is stored on

the rising edge of the appropriate clock input (CLKAB/LEAB or CLKBA/LEBA). In the latch mode, the clock

inputs serve as active-high transparent latch enables.

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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
