TRI-STATE Octal D-Type Transparent
Latches and Edge-Triggered Flip-Flops
General Description
These 8-bit registers feature totem-pole TRI-STATE outputs
designed specifically for driving highly-capacitive or relative-
ly low-impedance loads The high-impedance state and in-
creased 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 inter-
face or pull-up components They are particularly attractive
for implementing buffer registers I O ports bidirectional
bus drivers and working registers
