Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74ABT623 is a 3.3-V ABT 8-bit bus transceiver and register from Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 4.5 V to 5.5 V (compatible with 3.3-V systems)
- **Operating Temperature Range:** -40°C to +85°C
- **Input/Output Type:** 5-V tolerant inputs and outputs
- **Logic Family:** ABT (Advanced BiCMOS Technology)
- **Package Options:** SOIC, SSOP, TSSOP

### **Descriptions:**
- The SN74ABT623 combines an 8-bit transceiver with D-type flip-flops, allowing data to be stored or transmitted bidirectionally.
- It features separate control inputs for data flow direction (DIR) and output enable (OE).
- Designed for high-speed, low-power operation in mixed 3.3-V and 5-V systems.

### **Features:**
- **Bidirectional Data Flow:** Controlled by DIR input.
- **Output Enable (OE):** Disables outputs when high.
- **3-State Outputs:** Supports bus-oriented applications.
- **High-Speed Operation:** Typical propagation delay of 4.5 ns.
- **5-V Tolerant Inputs:** Allows interfacing with 5-V logic.
- **Low Power Consumption:** Reduced power dissipation compared to standard TTL.
- **Bus Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.

This device is commonly used in data communication, buffering, and bus interface applications.
