MC74HC14A is a hex Schmitt-trigger inverter with high-performance silicon-gate CMOS. 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. Features include: 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 μA; High Noise Immunity Characteristic of CMOS Devices; In Compliance With the JEDEC Standard No. 7.0 A Requirements; Chip Complexity: 60 FETs or 15 Equivalent Gates; Pb−Free Packages are Available.
The MC74HC14A is a hex Schmitt‑trigger inverter compatible with LS14, LS04 and HC04 pinouts. It offers high noise immunity and is useful for squaring up slow input signals in noisy environments. The device operates from 2.0 V to 6.0 V and can drive up to ten LSTTL loads per output.
