MC74HC14A
Hex Schmitt-Trigger
Inverter
High–Performance Silicon–Gate CMOS
The MC74HC14A 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 HC14A is useful to “square up” slow input rise and fall times.
Due to hysteresis voltage of the Schmitt trigger, the HC14A finds
applications in noisy environments.
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS and TTL
Operating Voltage Range: 2 to 6V
Low Input Current: 1µA
High Noise Immunity Characteristic of CMOS Devices
In Compliance With the JEDEC Standard No. 7A Requirements
Chip Complexity: 60 FETs or 15 Equivalent Gates

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 high–impedance cir-
cuit. For proper operation, Vin and
v vVout should be constrained to the
range GND (Vin or Vout) 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.
Functional operation should be restricted to the Recommended Operating Conditions.
†Derating — Plastic DIP: – 10 mW/_ C from 65_ to 125_ C
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 High–Speed CMOS Data Book (DL129/D).
