description
These 10-bit flip-flops feature 3-state outputs designed specifically for driving highly-capacitive or relatively
low-impedance loads. They are particularly suitable for implementing wider buffer registers, I/O ports,
bidirectional bus drivers with parity, and working registers.
The ten flip-flops are edge-triggered D-type flip-flops. On the positive transition of the clock the Q outputs on
the ’AS821 will be true, and on the ’AS822 will be complementary to the data input.
A buffered output-control input can be used to place the ten outputs in either a normal logic state (high or low
levels) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines
significantly. The high-impedance state and increased drive provide the capability to drive the bus lines in a
bus-organized system without need for interface or pullup components. The output control (OC) does not affect
the internal operation of the flip-flops. Old data can be retained or new data can be entered while the outputs
are in the high-impedance state.
The SN54AS’ family is characterized for operation over the full military temperature range of – 55
°C to 125°C.
The SN74AS’ family is characterized for operation from 0
°C to 70°C.
