Description

  • Function: The 74LS26 contains four 2-input NAND gates with open-collector outputs. This allows the output to be pulled to a voltage higher than the supply voltage, making it suitable for interfacing with high-voltage systems.
  • Open-Collector Outputs: These outputs require external pull-up resistors and are capable of sinking current when the output is low (logic 0). When the output is high (logic 1), the transistor is off, and the output is left floating (high-impedance), allowing it to be pulled up to a higher voltage.
  • Package: Available in a DIP-14 (Dual Inline Package) configuration, making it suitable for breadboard prototyping or through-hole PCB designs.

Features

  • Quad 2-Input NAND Gates: Contains four independent 2-input NAND gates in a single IC.
  • High-Voltage Interface: Designed to interface with high-voltage systems due to open-collector outputs.
  • Open-Collector Outputs: Allow control of higher voltage or current with external pull-up resistors.
  • TTL Compatibility: Fully compatible with standard TTL logic levels at the inputs.
  • Increased Drive Capability: Can sink significant current, making it useful for driving external loads such as relays, LEDs, or other devices requiring higher voltage/current.
  • Low Power Consumption: Uses LS (Low Power Schottky) technology for reduced power consumption.
  • Wide Operating Voltage: Can interface with voltages higher than the standard 5V logic, as the open-collector output can pull up to higher voltages.

Specifications

  • Supply Voltage (Vcc): 4.75V to 5.25V
  • Input High Voltage (VIH): Minimum 2V
  • Input Low Voltage (VIL): Maximum 0.8V
  • Output Sink Current: Capable of sinking up to 40 mA
  • Open-Collector Output Voltage: Can pull up to higher voltages (determined by external pull-up resistor and load)
  • Propagation Delay: Typically 20 ns
  • Operating Temperature Range: 0°C to 70°C (commercial grade)
  • Package Type: DIP-14 (Dual Inline Package)
