Texas Instruments SN74AC3G98/SN74AC3G98-Q1 Gates

Texas Instruments SN74AC3G98/SN74AC3G98-Q1 Gates incorporate three independent '98 function configurable logic gates with Schmitt-trigger inputs. Each gate can be adjusted to a variety of 1- and 2-input logic functions by connecting unused inputs to the supply or ground.

The TI SN74AC3G98-Q1 is AEC-Q100 qualified for automotive applications.

Features

  • AEC-Q100 qualified for automotive applications (SN74AC3G98-Q1):
    • Device temperature grade 1 of -40°C to +125°C
    • Device HBM ESD classification level 2
    • Device CDM ESD classification level C4B
  • Available in a wettable flank QFN package
  • Wide operating range of 1.5V to 6V
  • Inputs accept voltages up to 6V
  • Continuous ±24mA output drive at 5V
  • Supports up to ±75mA output drive at 5V in short bursts
  • Drives 50Ω transmission lines
  • Maximum tpd of 6ns at 5V, 50pF load
  • Each channel is independently configurable as:
    • 2-to-1 data selector or multiplexer with inverted output
    • Two-input NAND or NOR gate
    • Two-input AND, NAND, OR, or NOR gate with one inverted input
    • Buffer or inverter

Applications

  • Combine power good signals
