SN54BCT646J

The SN54BCT646J consist of bus transceiver circuits, D-type flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from the internal registers. The feature of SN54BCT646J are as follows: (1)State-of-the-Art BiCMOS Design Significantly Reduces ICCZ; (2)Bus Transceivers/Registers; (3)Independent Registers and Enables for A and B Buses; (4)Multiplexed Real-Time and Stored Data; (5)ESD Protection Exceeds JESD 22: 2000-V Human-Body Model (A114-A), 200-V Machine Model (A115-A).

The absolute maximum ratings of the SN54BCT646J are: (1)Supply voltage range, VCC: 0.5 V to 7 V; (2)Input voltage range: Control inputs: 0.5 V to 7 V, I/O ports: 0.5 V to 5.5 V; (3)Voltage range applied to any output in the disabled or power-off state, VO: 0.5 V to 7 V; (4)Voltage range applied to any output in the high state, VO: 0.5 V to VCC; (5)Current into any output in the low state: 96 mA; (6)Package thermal impedance, JA DW package: 46°C/W, NT package: 67°C/W; (7)Storage temperature range, Tstg: 65°C to 150°C.
