SN74HC14N 是一款六路反相施密特触发器（Hex Inverters with Schmitt-Trigger Inputs）: 六路反相施密特触发器. 芯片型号中的 HC 是 High Speed CMOS 的缩写，表示高速 CMOS 器件。 数据手册中的 Hex 是六的意思，不是十六或十六进制。 反相（Inverter）是指输入低电平输出高电平；输入高电平输出低电平。 因为其本身是一个集成了运放反相施密特触发器电路的芯片，不理解的话可以再次学习 运放教程2-正反馈电路。 74HC14 的功能引脚图： SN74HC14N 引脚图. A 表示 …
74HC14PW (Hex inverting Schmitt trigger) - Nexperia
The 74HC14; 74HCT14 is a hex inverter with Schmitt-trigger inputs. This device features reduced input threshold levels to allow interfacing to TTL logic levels. Inputs also include clamp diodes, this enables the use of current limiting resistors to interface inputs to voltages in excess of V CC.

The M74HC14 is a high speed CMOS hex Schmitt inverter fabricated with silicon gate C2MOS technology. Pin configuration and functions are the same as those of the M74HC04 but all inputs have a 20 % VCC hysteresis level. This, together with the Schmitt trigger function, allows the device to be used on line receivers with slow rise/fall input signals.
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.
The MC74HC14A/MC74HCT14A is useful to “square up” slow input rise and fall times. Due to hysteresis voltage of the Schmitt trigger, the device finds applications in noisy environments. The MC74HC14A has CMOS−level input thresholds while the …
The MM74HC14 utilizes advanced silicon−gate CMOS technology to achieve the low power dissipation and high noise immunity of standard CMOS, as well as the capability to drive 10 LS−TTL loads. The 74HC logic family is functionally and pinout compatible with the standard 74LS logic family.
