8-BIT TTL/BTL REGISTERED TRANSCEIVER

The SN74FB2033H 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 SN74FB2033H is specifically designed to be compatible with IEEE 1194.1-1991 (BTL) standard. 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 pins serve as active-high transparent latch enables.
