Description and Introduction

OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS The SN64BCT245N is a part manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Category:** Logic - Buffers, Drivers, Receivers, Transceivers  
- **Type:** Octal Bus Transceiver  
- **Technology:** BCT (BiCMOS)  
- **Number of Bits:** 8  
- **Voltage Supply:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** PDIP-20 (Plastic DIP)  
- **Logic Family:** BCT  
- **Logic Type:** CMOS  
- **Output Type:** 3-State  
- **Propagation Delay Time:** 6.5 ns (max)  
- **High-Level Output Current:** -15 mA  
- **Low-Level Output Current:** 24 mA  

### **Descriptions:**  
The SN64BCT245N is an octal bus transceiver designed for asynchronous communication between data buses. It features non-inverting 3-state outputs and is compatible with TTL input and output levels. The direction of data flow is controlled by the DIR (Direction Control) input, while the Output Enable (OE) input disables the outputs when high.  

### **Features:**  
- **BiCMOS Technology:** Combines high-speed bipolar performance with low-power CMOS.  
- **3-State Outputs:** Allows multiple outputs to be connected to a common bus.  
- **Wide Operating Voltage:** Supports 4.5V to 5.5V operation.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with TTL logic levels.  
- **High Drive Capability:** Suitable for driving heavily loaded buses.  
- **ESD Protection:** Provides protection against electrostatic discharge.  
- **Industrial Temperature Range:** Operates reliably from -40°C to +85°C.  

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

Application Scenarios & Design Considerations

OCTAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS

Alternative Part Number

  • 74BCT245APC --: Octal bus transceiver in the BCT family with similar TTL-compatible inputs and 5V operation, pin-compatible DIP-20 package.
  • CY74FCT245ATPC --: FCT octal bus transceiver offering comparable speed and drive, available in DIP-20 and functionally interchangeable in most designs.
  • MC74ACT245N --: ACT octal bus transceiver with TTL-compatible inputs and similar 5V CMOS performance, widely available in DIP-20.
  • 74BCT245PC --: Same BCT octal bus transceiver function in a DIP-20 package, pin-compatible with the SN64BCT245N.
  • CY74FCT245TPC --: FCT octal bus transceiver with equivalent 245 function and DIP-20 pinout, suitable as a functional drop-in replacement.
  • MC74F245N --: Octal bus transceiver in DIP-20 with similar TTL-compatible drive characteristics, usable where full BCT temperature range is not required.
