General Description
These 8-bit registers feature totem-pole TRI-STATE outputs designed specifically for driving highly-capacitive or relatively low-impedance loads. The high-impedance state and increased high-logic level drive provide these registers with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for interface or pull-up components. They are particularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

Features
■ Choice of 8 latches or 8 D-type flip-flops in a single package
■ TRI-STATE bus-driving outputs
■ Full parallel-access for loading
■ Buffered control inputs
■ P-N-P inputs reduce D-C loading on data lines
