The SN74BCT2953 octal bus transceiver contains two 8-bit back-to-back registers that store data flowing in both directions between two bidirectional buses. Data on the A or B bus is stored in the registers on the low-to-high transition of the clock (CLKAB or CLKBA) input provided that the clock-enable (CLKENAB or CLKENBA) input is low. Taking the output-enable (OEAB or OEBA) input low allows access of the data on the output port (B port or A port). The SN74BCT2953 is characterized for operation from 0C to 70C.
