Product Summary

The NTE74HCT14 (14−lead DIP) and NTE74HCT14T (SOIC−14) are hex inverting Schmitt trigger devices that utilizes advanced silicon−gate CMOS technology to achieve the low-power dissipation and high-noise immunity of standard CMOS and the capability to drive 10 LS−TTL loads. Inputs are protected from damage due to static discharge by internal diode clamps to VCC and GND.

  • Propagation delay: 13ns (typ)
  • Wide power supply range: 4.5V to 5.5V
  • Low quiescent current: 10μA (max)
  • Low-input current: 1μA (max)
  • Fanout of 10 LS−TTL loads
  • Typical hysteresis voltage: 0.6V at VCC = 4.5V
  • TTL, LS pinout and input threshold compatible
