Description

The 74HC240 is part of the high-speed CMOS (HC) logic family and is designed to provide high-speed, low-power, and reliable operation. The IC contains eight independent buffers with three-state outputs. These buffers are designed to drive high-current loads and are suitable for interfacing between different logic levels or for driving data buses.

Features

  • Octal Buffer/Line Driver: Contains eight independent buffers/drivers.
  • Three-State Outputs: Outputs can be in high, low, or high-impedance state, allowing for bus interfacing.
  • High-Speed Operation: Fast propagation delays suitable for high-speed digital circuits.
  • Low Power Consumption: CMOS technology ensures minimal power consumption.
  • Wide Operating Voltage Range: Compatible with a broad range of supply voltages.
  • High Noise Immunity: Reliable operation in noisy environments.

Specifications

  • Package: DIP-20
  • Supply Voltage (Vcc): 2V to 6V
  • Input Voltage (Vin): 0V to Vcc
  • Output Voltage (Vout): 0V to Vcc
  • Propagation Delay (tpd): Typically 10 ns (depends on supply voltage and load capacitance)
  • Input Capacitance (Cin): Typical value is 3 pF
  • Output Drive Current:
    • High-Level Output Current (IOH): -20 mA
    • Low-Level Output Current (IOL): 20 mA
  • Logic Levels:
    • Input Low Voltage (VIL): ≤ 0.3 x Vcc
    • Input High Voltage (VIH): ≥ 0.7 x Vcc
    • Output Low Voltage (VOL): ≤ 0.1 x Vcc (at IOL = 20 mA)
    • Output High Voltage (VOH): ≥ 0.9 x Vcc (at IOH = -20 mA)
  • Current Consumption (ICC): Typically 1 µA (static), varies with speed and load
