### **Descriptions:**
The SN74AS374 is an octal D-type flip-flop with edge-triggered operation and 3-state outputs. It is designed for bus-oriented applications where multiple devices share a common bus. The flip-flops capture data on the low-to-high transition of the clock (CLK) input. The outputs are controlled by an output enable (OE) input, which, when high, places the outputs in a high-impedance state.
### **Features:**
- **Edge-Triggered D-Type Flip-Flops:** Data is latched on the rising edge of the clock.
- **3-State Outputs:** Allows direct connection to a bus line.
- **High-Speed Operation:** Optimized for performance with typical propagation delays of 9 ns.
- **Bus-Structured Pinout:** Facilitates parallel data transfer.
- **Wide Operating Voltage Range:** 4.5V to 5.5V.
- **TTL-Compatible Inputs and Outputs:** Ensures compatibility with standard TTL logic levels.
- **High Drive Outputs:** Capable of driving heavily loaded bus lines.
