Product Summary

The SN74LS373DW is an octal D-type transparent latch and edge-triggered flip-flop. The SN74LS373DW feature 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 these registers with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for interface or pullup components. The SN74LS373DW is particularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

Parametrics

SN74LS373DW 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)DW package : 58℃/W; (6)N package : 69℃/W; (7)NS package : 60℃/W; (8)Storage temperature range, Tstg : –65℃ to 150℃.

Features

SN74LS373DW 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 (S373 and S374); (6)P-N-P Inputs Reduce DC Loading on Data Lines (S373 and S374).
