description
The CD74FCT821A is a 10-bit flip-flop that features 3-state outputs designed specifically for driving highly
capacitive or relatively low-impedance loads. It is particularly suitable for implementing wider buffer registers,
I/O ports, bidirectional bus drivers with parity, and working registers.
This device uses a small-geometry BiCMOS technology. The output stage is a combination of bipolar and
CMOS transistors that limits the output high level to two diode drops below V
CC
. This resultant lowering of output
swing (0 V to 3.7 V) reduces power-bus ringing [a source of electromagnetic interference (EMI)] and minimizes
V
CC
bounce and ground bounce and their effects during simultaneous output switching. The output
configuration also enhances switching speed and is capable of sinking 48 mA.
The flip-flops enter data into their registers on the low-to-high transition of the clock (CLK). The Q outputs are
noninverted data. The output-enable (OE
) input controls the 3-state outputs and is independent of register
operation. When OE
is high, the outputs are in the high-impedance state.
The CD74FCT821A is characterized for operation from 0°C to 70°C.
