Description and Introduction

OCTAL D-TYPE FLIP-FLOP WITH 3-STATE OUTPUT The TC74VHCT374AF is a high-speed CMOS octal D-type flip-flop manufactured by Toshiba. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Octal D-Type Flip-Flop with 3-State Outputs  
- **Technology:** CMOS  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Input Voltage (VIH):** 2.0V (min)  
- **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **High-Level Output Voltage (VOH):** 4.4V (min at IOH = -6mA)  
- **Low-Level Output Voltage (VOL):** 0.1V (max at IOL = 6mA)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Propagation Delay (tpd):** 6.5ns (max at VCC = 5V, CL = 50pF)  
- **Output Current (IO):** ±8mA  
- **Package Type:** TSSOP-20  

### **Descriptions:**  
- The TC74VHCT374AF is a high-speed, low-power octal flip-flop with 3-state outputs.  
- It features a common clock (CP) and output enable (OE) control for all eight flip-flops.  
- Designed for bus interface applications, it ensures minimal power consumption while maintaining high-speed operation.  

### **Features:**  
- **High-Speed Operation:** Optimized for 5V systems with fast propagation delay.  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation.  
- **3-State Outputs:** Allows direct connection to a bus-oriented system.  
- **TTL-Compatible Inputs:** Can interface with TTL logic levels.  
- **Wide Operating Voltage Range:** Supports 4.5V to 5.5V operation.  
- **Balanced Propagation Delays:** Ensures reliable timing performance.  
- **ESD Protection:** Provides robustness against electrostatic discharge.  

This information is based on Toshiba's official documentation for the TC74VHCT374AF.
