74VHCT14ASJ

六角施密特逆变器 Hex Schmitt Inverter

General Description

The VHCT14A is an advanced high speed CMOS Hex Schmitt Inverter fabricated with silicon gate CMOS technology. The VHCT14A contains six independent inverters which are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. Protection circuits ensure that 0V to 7V can be applied to the input pins without regard to the supply voltage and to the output pins with VCC   0V. These circuits prevent device destruction due to mismatched supply and input/output voltages. This device can be used to interface 3V to

5V systems and two supply systems such as battery backup.
