74HC14
Hex Schmitt−Trigger
Inverter
HighPerformance SiliconGate CMOS
The 74HC14 is identical in pinout to the LS14, LS04 and the HC04.
The device inputs are compatible with Standard CMOS outputs; with
pullup resistors, they are compatible with LSTTL outputs.
The HC14 is useful to “square up” slow input rise and fall times.
Due to hysteresis voltage of the Schmitt trigger, the HC14 finds
applications in noisy environments.
Features
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS and TTL
Operating Voltage Range: 2.0 to 6.0 V
Low Input Current: 1.0 mA
High Noise Immunity Characteristic of CMOS Devices
In Compliance With the JEDEC Standard No. 7A Requirements
ESD Performance: HBM > 2000 V; Machine Model > 200 V
Chip Complexity: 60 FETs or 15 Equivalent Gates
These are PbFree Devices

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this highimpedance cir-
cuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress
ratings only. Functional operation above the Recommended Operating Conditions is not im-
plied. Extended exposure to stresses above the Recommended Operating Conditions may af-
fect device reliability.
†Derating — SOIC Package: – 7 mW/_C from 65_ to 125_C
TSSOP Package: 6.1 mW/_C from 65_ to 125_C
For high frequency or heavy load considerations, see Chapter 2 of the ON Semiconductor HighSpeed CMOS Data Book (DL129/D).
