                                                74LCX821MSA Overview
The package is in the form of 24-SSOP (0.209, 5.30mm Width). Package Tubeembeds it. T flip flop is configured with an output of Tri-State, Non-Inverted. In the configuration of the trigger, Positive Edgeis used. It is mounted in the way of Surface Mount. The supply voltage is set to 2V~3.6V. It is operating at a temperature of -40°C~85°C TA. The type of this D latch is D-Type. This type of FPGA is a part of the 74LCX series. You should not exceed 150MHzin the output frequency of the device. A total of 1elements are present in it. As a result, it consumes 10μA quiescent current. There are 24 terminations,Power is provided by a 2.5V supply. Its input capacitance is 7pF farads. This D flip flop belongs to the family of LVC/LCX/Z. There is a 3.6Vmaximum supply voltage (Vsup). The supply voltage (Vsup) should be kept above 2V for normal operation. This flip flop has a total of 2ports.
