Description and Introduction

3.3V CMOS OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS, 5 VOLT TOLERANT I/O AND BUS-HOLD The IDT74LVCH245AQ is a high-performance, low-voltage CMOS octal bus transceiver from Integrated Device Technology (IDT). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Integrated Device Technology (IDT)  

### **Part Number:**  
IDT74LVCH245AQ  

### **Description:**  
The IDT74LVCH245AQ is an octal bus transceiver designed for asynchronous communication between data buses. It features non-inverting 3-state outputs and operates at low voltage with high-speed performance.  

### **Key Features:**  
- **Logic Family:** LVCH (Low-Voltage CMOS with TTL-compatible inputs)  
- **Voltage Supply Range:** 1.65V to 3.6V  
- **High-Speed Operation:** 3.5 ns max propagation delay at 3.3V  
- **3-State Outputs:** Allows bus isolation  
- **Bus Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors  
- **Power-Down Protection:** Inputs/outputs tolerate up to 5.5V  
- **Drive Capability:** ±24 mA output drive at 3.0V  
- **ESD Protection:** >2000V per JESD22-A114  
- **Package Options:** TSSOP (Thin Shrink Small Outline Package)  

### **Applications:**  
- Data bus communication  
- Memory interfacing  
- Level shifting in mixed-voltage systems  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

3.3V CMOS OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS, 5 VOLT TOLERANT I/O AND BUS-HOLD

Alternative Part Number

  • SN74LVCH245ADW --: Same LVCH-family octal bus transceiver with 3.3V operation and 5V-tolerant inputs, widely available and pin-compatible in SOIC-20.
  • MC74LCX245ADW --: LCX-family octal bus transceiver offering comparable low-voltage CMOS performance and 5V-tolerant I/O, suitable functional replacement.
  • 74LVC245APW --: LVC octal bus transceiver with similar 3.3V logic levels and bus-hold behavior, commonly used as a drop-in alternative in TSSOP-20.
