Description

The SN54ABT16470 are 16-bit registered transceivers that contain two sets of D-type flip-flops for temporary storage of data flowing in either direction. The SN54ABT16470  can be used as two 8-bit transceivers or one 16-bit transceiver. Separate clock (CLKAB or CLKBA) and output-enable  (OEAB or OEBA ) inputs are provided for each register to permit independent control in either direction of data flow.To avoid false clocking of the flip-flops, clock enable (CLKEN ) should not be switched from high to low while CLK is high.
