Product Summary
The SN54S373J is an octal D-type transparent latch and edge-triggered flip-flop. It features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. The high-impedance 3-state and increased high-logic-level drive provide the SN54S373J with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for interface or pull-up components. The SN54S373J is particularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
Parametrics
SN54S373J absolute maximum ratings: (1)Supply voltage, VCC: 7V; (2)Input voltage, VI: 7V; (3)Off-state output voltage: 5.5V; (4)Package thermal impedance, θJA : DB package: 70℃/W; (5)DW package: 58℃/W; (6)N package: 69℃/W; (7)NS package: 60℃/W; (8)Storage temperature range, Tstg:–65℃ to 150℃.
Features
SN54S373J 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 (’373 and ’374); (6)P-N-P Inputs Reduce DC Loading on Data Lines (’373 and ’374).
