The PI74FCT377T is an 8-bit wide octal designed with eight edge- triggered D-type flip-flops with individual D inputs and O outputs. When Clock Enable (CE) is LOW, the common buffered Clock (CP) loads all flip-flops simultaneously. The register is fully edge- triggered. D input state, one setup time before the LOW-to-HIGH clock transition, is transferred to the corresponding flip-flop’s O output. The CE input must be stable only one setup time prior to the LOW-to-HIGH transition for predictable operation. Product Features: • The PI74FCT377T is pin compatible with bipolar FAST™ Series at a higher speed and lower power consumption • TTL input and output levels • Octal D flip-flops with Clock Enable • Extremely low static power • Hysteresis on all inputs • Industrial operating temperature range: –40°C to +85°C • Packages available: – 20-pin 173 mil wide plastic TSSOP (L) – 20-pin 300 mil wide plastic DIP (P) – 20-pin 150 mil wide plastic QSOP (Q) – 20-pin 150 mil wide plastic TQSOP (R) – 20-pin 300 mil wide plastic SOIC (S) Logic Block Diagram Inputs Outputs Mode CP CE DN ON Load "1" ↑ lh H Load "0" ↑ ll L Hold ↑ hX NC (Do Nothing) HHX NC Truth Table (1) 1.
