Description

These 8-bit flip-flops with 3-state outputs of SN54ABT534 are designed specifically for driving highly capacitive or relatively low-impedance loads. SN54ABT534 is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The eight flip-flops of SN54ABT534 are edge-triggered D-type flip-flops. On the positive transition of the clock (CLK), the Q outputs are set to the complement of the logic levels set up at the data (D) inputs.
