MOTOROLA

SEMICONDUCTOR TECHNICAL DATA

Hex Schmitt-Trigger Inverter

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 ªsquare upº 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 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.

*Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the Recommended Operating Conditions.

²Derating Ð Plastic DIP: ± 10 mW/ _C from 65_ to 125_C
