Description and Introduction

Single-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs The SN74AVCH1T45DCKR is a single-bit dual-supply bus transceiver manufactured by Texas Instruments.  

### **Specifications:**  
- **Technology:** CMOS  
- **Supply Voltage Range (VCCA):** 0.8V to 3.6V  
- **Supply Voltage Range (VCCB):** 0.8V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SC70 (DCK), 6-pin  
- **Logic Type:** Voltage Level Translator  
- **Data Rate:** Up to 500 Mbps  
- **Input/Output Type:** Tri-State  
- **ESD Protection:** Exceeds 2000V HBM  

### **Descriptions:**  
- A single-bit, non-inverting bus transceiver with configurable voltage translation.  
- Allows bidirectional voltage translation between different voltage nodes (e.g., 1.2V, 1.8V, 2.5V, 3.3V).  
- Features an output enable (OE) input to disable the outputs for bus isolation.  

### **Features:**  
- **Bidirectional Voltage Translation:** Supports mixed-voltage communication.  
- **Partial Power-Down Protection:** I/Os are disabled when either VCC is at GND.  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Wide Operating Voltage Range:** Compatible with various logic levels.  
- **Robust Design:** High noise immunity and ESD protection.  

This device is commonly used in applications such as smartphones, tablets, and other portable electronics requiring voltage level shifting.

Description and Introduction

Single-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs The SN74AVCH1T45DCKR is a single-bit dual-supply bus transceiver manufactured by Texas Instruments (TI).  

**Key Specifications:**  
- **Logic Type:** Voltage Level Translator  
- **Number of Bits:** 1  
- **Voltage - Supply (VccA):** 0.8V to 3.6V  
- **Voltage - Supply (VccB):** 0.8V to 3.6V  
- **Operating Temperature:** -40°C to 85°C  
- **Package/Case:** SC-70-6  
- **Mounting Type:** Surface Mount  

**Features:**  
- Bidirectional voltage translation between different supply voltages (0.8V to 3.6V)  
- Supports partial power-down mode (Ioff)  
- Low static and dynamic power consumption  
- Latch-up performance exceeds 100mA per JESD 78  
- ESD protection exceeds JESD 22 (2000V HBM, 1000V CDM)  

**Description:**  
The SN74AVCH1T45DCKR is designed for asynchronous communication between data buses operating at different voltage levels. It provides bidirectional voltage translation with automatic direction sensing, eliminating the need for a direction control signal. The device is optimized for low-power applications and features high-speed operation with minimal propagation delay.
