Description and Introduction

OCTAL D-TYPE FLIP-FLOPS WITH CLOCK ENABLE The SN74HCT377DWRG4 is a D-type flip-flop integrated circuit manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Series:** 74HCT  
- **Logic Type:** D-Type Flip-Flop  
- **Number of Bits:** 8  
- **Input Type:** Single-Ended  
- **Output Type:** Tri-State, Non-Inverted  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Input Voltage (VIH):** 2V (min)  
- **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **High-Level Output Current (IOH):** -6mA  
- **Low-Level Output Current (IOL):** 6mA  
- **Propagation Delay Time (tpd):** 25ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SOIC-20  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74HCT377DWRG4 is an octal D-type flip-flop with a common clock (CP) and output enable (OE) control.  
- It features edge-triggered flip-flops with data inputs (D0-D7) that are transferred to outputs (Q0-Q7) on the rising edge of the clock pulse.  
- The output enable (OE) controls the tri-state outputs, allowing them to be placed in a high-impedance state when OE is high.  

### **Features:**  
- **8-Bit Parallel Register:** Stores 8 bits of data.  
- **Edge-Triggered Clocking:** Data is latched on the rising edge of the clock.  
- **Tri-State Outputs:** Allows bus-oriented operation.  
- **Wide Operating Voltage:** 4.5V to 5.5V.  
- **HCT Input Compatibility:** TTL-level compatible inputs.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  

This information is strictly factual and derived from the manufacturer's datasheet.

Application Scenarios & Design Considerations

OCTAL D-TYPE FLIP-FLOPS WITH CLOCK ENABLE

Alternative Part Number

  • MC74HCT377ADWR2G --: Same HCT octal D flip-flop function with 3-state outputs in a SOIC-20 wide package, direct functional and pin-compatible replacement.
  • 74HCT377D,653 --: HCT logic octal D-type flip-flop with 3-state outputs, same function and SOIC-20 package, suitable drop-in alternative.
  • CD74HCT377M96 --: Equivalent HCT octal D flip-flop from the same logic family with 3-state outputs, though in a narrower SOIC package requiring layout check.
  • CD74HCT377M --: Same HCT logic family octal D flip-flop with clear, functionally equivalent and widely available in SOIC package.
  • 74HCT377D --: Standard 74HCT377 octal D-type flip-flop with clear in SOIC, same logic function and compatible electrical characteristics.
