Product Summary
The 8-bit register SN54LS374J features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. The eight flip-flops of the SN54LS374J is an edge-triggered D-type flip-flop. Schmitt-trigger buffered inputs at the enable/clock lines of the SN54LS374J simplify system design as ac and dc noise rejection is improved by typically 400 mV due to the input hysteresis.
Parametrics
SN54LS374J absolute maximum ratings: (1)Supply voltage, VCC: 7 V; (2)Input voltage, VI: 7 V; (3)Off-state output voltage: 5.5 V; (4)Package thermal impedance, θJA (see Note 2): DB package: 70℃/W; (5)Storage temperature range, Tstg: -65℃ to 150℃.
Features
SN54LS374J features: (1)Choice of Eight Latches or Eight D-Type Flip-Flops in a Single Package; (2)3-State Bus-Driving Outputs; (3)Full Parallel Access for Loading; (4)Buffered Control Inputs; (5)Clock-Enable Input Has Hysteresis to Improve Noise Rejection; (6)P-N-P Inputs Reduce DC Loading on Data Lines.
