NTE74HC14
Integrated Circuit
TTL − High Speed CMOS, Hex Schmitt Trigger Inverter
Description:
The NTE74HC14 is a hex Schmitt Trigger inverter in a 14−Lead plastic DIP type package and is useful
to “square−up” slow input rise and fall times. Due to hysteresis voltage of the Schmitt Trigger, the
NTE74HC14 finds applications in noisy environments.
The NTE74HC14 is identical in pinout to the ’LS14, LS04 and the HC04 and the device inputs are
compatible with Standard CMOS outputs; with pullup resistors, they are compatible with LSTTL
outputs.
Features:
D Output Drive Capability: 10 LSTTL Loads
D Outputs Directly Interface to CMOS, NMOS, and TTL
D Operating Voltage range: 2V to 6V
D Low Input Current: 1.0μA
D High Noise Immunity Characteristics of CMOS Devices

Note 1. Stresses exceeding the Absolute Maximum Ratings may damage the device. The device may
not function or be operable above the Recommended Operating Conditions and stressing the
parts to these levels is not recommended. In addition, extended exposure to stresses above
the Recommended Operating Conditions may effect device reliability. The Absolute Maximum
Ratings are stress ratings only.
Note 2. Unless otherwise specified, all voltages are referenced to GND.
Note 3. Power Dissipation temperature derating: 12mW/°C from +65°C to +85°C.
