Latches and Edge-Triggered Flip-Flops
General Description
These 8-bit registers featuretotem-pole TRI-STATE outputs
designed specificallyfor driving highly-capacitiveor relative- low-impedance loads. The high-impedance stateandin-
creased high-logic level drive provide these registers with
the capabilityof being connected directlytoand drivingthe
bus linesina bus-organized system without needfor inter-
faceor pull-up components. Theyare particularly attractive
for implementing buffer registers, I/O ports, bidirectional
bus drivers,and working registers. (Continued)
