特長

  • Enhanced N-channel FET with no inherent diode to VCC
  • 5Ω bidirectional switches connect inputs to outputs
  • Zero propagation delay, zero ground bounce
  • Undershoot clamp diodes on all switch and control inputs
  • Available in 20-pin QSOP, SOIC, and TSSOP packages

説明

The QS3244 provides a set of eight high-speed CMOS TTL-compatible bus switches in a pinout compatible with 74FCT244, 74F244, 74ALS/AS/LS244 8-bit drivers. The low ON-resistance (5Ω) of the QS3244 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. The QS3244 operates at -40 °C to +85 °C.
