双4位D型边沿触发触发器 DUAL 4-BIT D-TYPE EDGE-TRIGGERED FLIP-FLOPS
description
These dual 4-bit D-type edge-triggered flip-flops feature 3-state outputs designed specifically as bus drivers. They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
• 3-State Buffer-Type Outputs Drive Bus Lines Directly
• Bus-Structured Pinout
• Choice of True or Inverting Logic
– SN54ALS874B, SN74ALS874B, SN74AS874 Have True Outputs
– SN74ALS876A, SN74AS876 Have Inverting Outputs
• Asynchronous Clear
• Package Options Include Plastic Small-Outline DW Packages, Plastic FN and Ceramic FK Chip Carriers, and Standard Plastic NT and Ceramic JT 300-mil DIPs
