7.4 Device Functional Modes

Table 7-1 is the function table for the SN54SC2T74-SEP.

Table 7-1 Function Table
INPUTS(1) OUTPUTS
PRE CLR CLK D Q Q
L H X X H L
H L X X L H
L L X X H(1) H(1)
H H ↑ H H L
H H ↑ L L H
H H L X Q0 Q0
(1) H = high voltage level, L = low voltage level, X = do not care, Z = high impedance
(1) This configuration is nonstable; that is, it does not persist when PRE​​ or CLR​​ returns to its inactive (high) level.
