High–Performance Silicon–Gate CMOS
The MC54/74HC14A 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 circuit. For proper operation, Vin and
V
out
should be constrained to the
range GND v (Vin or V
out
) 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.
