SN74BCT574NSRE4 Texas Instruments Integrated Circuit (Small Outline Packages) In Stock

What are the key features of SN74BCT574NSRE4?

• 8-bit octal flip-flop with 3-state bus outputs: buffers and registers 8 parallel data lines for address or data bus pipeline stages at up to 77 MHz clock frequency
• BCT logic family: BiCMOS technology provides TTL-compatible inputs with CMOS output drive, delivering 64 mA output sink current for driving backplane and memory bus loads with 50 pF capacitance
• Active-low output enable (OE): allows multiple SN74BCT574 devices to share a common bus with true high-impedance 3-state outputs, preventing bus contention in multi-master systems

What is SN74BCT574NSRE4 used for?

The SN74BCT574NSRE4 is used as an 8-bit data or address bus register in microprocessor and DSP system designs where it captures parallel data on the rising clock edge and holds it stable for downstream logic or memory bus interfaces operating at up to 77 MHz. Its 64 mA output sink current and 50 pF load specification make it suitable for driving heavily loaded VME, ISA, or custom backplane buses where standard CMOS logic lacks sufficient drive strength. The device also serves as an output port register in FPGA-based systems needing a buffered latch with 3-state capability to interface with TTL-level peripheral buses.
