Description and Introduction

Octal 3-STATE Buffer/Line Driver/Line Receiver The 74LS240 is a part of the 74LS series of logic ICs, which are manufactured by various companies, including HIT (Hitachi). The 74LS240 is an octal buffer/line driver with 3-state outputs. It is designed to be used in bus-oriented systems and features inverting outputs. The device is organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs. When OE is high, the outputs are in a high-impedance state.

Key specifications of the 74LS240 include:

- **Supply Voltage (VCC):** 4.75V to 5.25V
- **Input Voltage (VI):** 0V to VCC
- **Output Voltage (VO):** 0V to VCC
- **Operating Temperature Range:** 0°C to 70°C
- **Propagation Delay Time (tPLH, tPHL):** Typically 12ns at 5V
- **Output Current (IOH/IOL):** ±15mA
- **Input Current (II):** ±0.4mA
- **Power Dissipation (PD):** 80mW (typical)

The 74LS240 is available in various package types, including DIP (Dual In-line Package) and SOIC (Small Outline Integrated Circuit). The device is designed to interface with TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) logic families.

Please note that while HIT (Hitachi) was a known manufacturer of the 74LS240, the part may also be available from other manufacturers, and specifications can vary slightly between different sources. Always refer to the specific datasheet provided by the manufacturer for the most accurate and detailed information.
