OCTAL BUS TRANSCEIVER The SN74LS245N is a part manufactured by Texas Instruments (not specifically by "MALAYSIA," which may refer to the manufacturing location). Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:
### **Specifications:**
- **Type:** Octal Bus Transceiver
- **Logic Family:** 74LS (Low-Power Schottky)
- **Number of Bits:** 8 (Octal)
- **Voltage Supply (VCC):** 4.75V to 5.25V (5V typical)
- **Operating Temperature Range:** 0°C to 70°C (Commercial grade)
- **Package:** 20-pin DIP (Dual In-line Package)
- **Direction Control:** Bidirectional with DIR (Direction) and OE (Output Enable) pins
- **Propagation Delay:** Typically 15ns
- **Output Current:** ±15mA (High-Level Output), 24mA (Low-Level Output)
- **Input Current:** ±0.36mA (High-Level Input), -1.6mA (Low-Level Input)
### **Descriptions:**
- The SN74LS245N is an 8-bit bidirectional bus transceiver designed for asynchronous two-way communication between data buses.
- It features separate input and output controls (OE and DIR) to manage data flow direction.
- Commonly used in digital systems for buffering and data transfer between buses.
### **Features:**
- **Bidirectional Data Flow:** Controlled by DIR pin (HIGH = A to B, LOW = B to A).
- **Output Enable (OE):** Disables outputs when HIGH (active LOW).
- **3-State Outputs:** Allows connection to a shared bus.
- **Low Power Consumption:** Typical of the 74LS series.
- **High Noise Immunity:** Schottky-clamped for improved performance.
This information is based on Texas Instruments' datasheet for the SN74LS245N. The part may be manufactured in Malaysia, but the manufacturer is Texas Instruments.
