description
The SN74FB2033K is an 8-bit transceiver featuring a split input (AI) and output (AO) bus on the TTL-level A 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.
